Additional Information
External relay at signal output V(X) (0-10V / PWM)
With the help of an external relay (art. no. 77502), a 0-10V/PWM output
V(X) (V1, V2) can be used to obtain a switching capacity of 230 VAC (I)
or a potential-free change-over contact (II). The external relay is then
activated via the signal output (0V = "off" (0 VAC or open or closed), 10V
= "on" (230VAC or closed or open).
1. Connect external 0-10V relay to signal output, e.g. V1.
2. Assign additional function to signal V1. See " Relay functions " on
page 43
3. Disable the speed control for the corresponding 0-10V / PWM output
(Off). See " Variant " on page 42
Electrical Terminals
For high-efficiency pumps with 0-10V / PWM signal input, the power can be provided (V1 /V2 parallel operation) over a free
relay.
The connection of the ground wire is made at the lower gray terminal block. The neutral conductor N is connected to terminal
block N. The PE protective conductor must be connected to the PE metal terminal block!

Electrical Connection
Before working on the unit, switch off the power supply and secure it against being switched on again! Check that there is no
power flowing! Electrical connections may only be made by a specialist and in compliance with the applicable regulations. The
unit may not be put into operation if there is visible damage to the housing, e.g. cracks.
The unit may not be accessible from behind.
Low-voltage cables such as temperature sensor cables must be routed separately from mains voltage cables. Feed tem-
perature sensor cables only into the left-hand side of the unit, and mains voltage cables only into the right-hand side.
The customer must provide an all-pole disconnecting device, e.g. an emergency heating switch.
The cables being connected to the unit must not be stripped by more than 55 mm, and the cable jacket must reach into the hous-
ing just to the other side of the strain relief.
Installing the Temperature Sensors
The controller operates with Pt1000 temperature sensors which are accurate to 1 °C, ensuring optimal control of system functions.
If desired, the sensor cables can be extended to a maximum of 30 m using a cable with a cross-section of at least 0.75 mm².
Ensure there is no contact resistance! Position the sensor precisely in the area to be measured! Only use immersion, pipe-
mounted or flat-mounted sensors suitable for the specific area of application with the appropriate permissible temperature
range.
Low-voltage cables such as temperature sensor cables must be routed separately from mains voltage cables. Feed tem-
perature sensor cables only into the left-hand side of the unit, and mains voltage cables only into the right-hand side.

Combining multiple SOREL products
SOREL devices with CAN Bus such as HCC controller, Datalogger or °CALEON Room Controller can be networked to communicate with
each other and intelligently control larger systems.
CAN bus
1. The CAN devices are connected in series with the CAN bus cable.
2. The first and last CAN device in this connection in series must be fitted with terminating
resistance.
The wiring of the two CAN sockets is arbitrary.
23
°CALEON Room Controllers
°CALEON is an optional accessory and is normally not included in the scope of supply.
Accessories
Each °CALEON comes with an accessory bag that contains everything (except the CAN cable) needed to connect to an HCC. The following
components are used for the electrical connection:
1. Molex adapter for the CAN connection
2. Single wire connector to easily connect the Molex adapter to the CAN cable
3. Terminating resistor for the 2nd CAN bus connection on the HCC (if it is not used).
Can cable: <3m; at >=3m a shielded, twisted-pair cable is to be used. Isolate shielding and connect it to the protective conductor
on one end. Max. cable length of the complete system 200 m.
Wiring
Cable strip off max. 55 mm, insulate all wire ends 8-9 mm and
insert shielding over the cable. Insulate the entire shielding with
tape.
Wire ferrules made of brass can be difficult to clamp due to their asymmetric crimping shape. In this case, remove the wire fer-
rule. The plug-in terminals are also suitable for flexible cables.
Any contact between protective conductor and circuit board can cause serious damage.
Wiring of a °CALEON with controller
When connecting the CAN-Bus cable, make sure that the correct pairs of wires are twisted. The assignment is identical to the
terminal pairs on the °CALEON room controller.
-> GND + 24VDC
-> CAN Low + CAN High
Wiring of several °CALEONs with controller
The 24V power supply of the LHCC is designed for a load of up to 6W. This can supply 3 °CALEON room controllers. For loads
> 6W, an external power supply must be used.
24
Configuration
First, the °CALEON must be set up directly on the room controller. The automatic start-up wizard (Overview > Operating Mode > Menu >
Expert > Factory Settings) and the °CALEON user manual will help you.
If not already done, set up the HCC now with the help of the commissioning wizard.
The setup of the room controller is done in the following menu:
5. Settings -> 5.1. Heating circuit 1 - > 5....24. Room controller
5....1. Thermostat
Here, you select the room created in °CALEON. The rooms represented by symbols in °CALEON are given written names in the HCC. The
assignment can be found in the following table.
Bathroom Children 3 Room 2
Bathroom 2 Corridor Room 3
Bathroom 3 Corridor 2 Room 4
25
Bathroom 4 Dining Room 5
Bedroom Kitchen Room 6
Bedroom 2 Living Room 7
Bedroom 3 Office Room 8
Children Office 2 Room 9
Children 2 Room 1 Room 10
5....12. Room controller
This value can be adjusted as to the amount of influence the room temperature will have on the reference flow temperature, as a percentage.
For each degree deviation between room temperature and reference temperature, the percentage of the calculated set flow temperature set
here is added to the set flow temperature or subtracted from it up to the min. or max. values set under the protective functions.
Example: Reference room temp.: e.g. 25 °C; room temp.: e.g. 20 °C ±5 °C. Calculated reference temp.: e.g. 40 °C: room controller: 10 %= 4
°C 5 X 4 °C= 20 °C. Accordingly, 20 °C are added to the reference flow temperature, giving 60 °C. If the value is higher than the one set in
"Max. flow temp", the resulting temperature will be the one set in "Max. flow temp".
The setting parameters "5....13. Room ref. day“ and "5....14. Room ref. night" have no influence, when using a °Caleon and can
be ignored.
Under "5…2. Thermostat" further °CALEONs can be set optionally as room controllers. The same system as for the first room controller
applies.
5. Settings -> 5.1. Heating circuit 1 -> 5.15. Heating circuit off
If you want the heating circuit to switch off in addition to summer-winter shutdown, even if the room temperature is reached, set "summer +
room" here.
RC21 Room thermostat with remote control
The RC21 room thermostat is an optional accessory and is normally not included in the scope of supply.
The remote control with integrated thermostat RC21 provides you with easy to use temperature controlled adjustment of the temperature
from within your living space.
Setting options
The RC21 control dial parallel shifts the heating circuit characteristic stored in the controller. The flow temperature (depending the outdoor
temperature) is increased or decreased respectively by this. When the dial is turned all the way down, the heat circuit is switched off. Frost
protection stays active to prevent damage.
Temperature Sensors
The RC21 room thermostat has a built-in temperature sensor, the values of which are registered, used and displayed in the controller. If the
settings in the controller allow it, the sensor is used to alter the flow temperature.
Operating Modes
The slider can be moved to the following operating modes.
In automatic mode, the temperature is controlled according to the set thermostat periods.
In continuous day mode, the set times are ignored and the temperature is controlled according to the day settings.
In continuous night mode, the temperature is usually reduced. This setting is suitable, for example, for periods of prolonged absence
(e.g. holidays).
Installation
Carefully remove the dial from the housing with a screwdriver. Loosen
the screw beneath. Remove the light-coloured part of the housing from
the base.
The RC21 is connected to the controller via 3 wires.
The following picture shows exemplary wiring.

5....12. Room Controller
This value is used to appoint the amount of influence the room temperature has on the reference flow temperature, as a percentage. For
each degree deviation between room temperature and reference temperature, the percentage of the calculated set flow temperature set
here is added to the set flow temperature or subtracted from it up to the min. or max. values set under the protective functions.
Example: Reference room temp.: 25 °C; room temp.: 20 °C = 5 °C deviation. Calculated reference flow temp.: 40 °C: room controller: 10
%= 4 °C 5 X 4 °C= 20 °C. Accordingly, 20 °C are added to the reference flow temperature, giving 60 °C. If the value is higher than the one
set in "Max. flow temp", the resulting temperature will be the one set in "Max. flow temp".
Under "5....2. Thermostat" further °CALEONs can be set optionally as room controllers. The same system as for the first room controller
applies.
5. Settings -> 5.1. Heating circuit 1 -> 5.15. Heating circuit off
If you want the heating circuit to switch off in addition to summer-winter shutdown, even if the room temperature is reached, set "summer +
room" here.
The RC21 is suited for low voltage only!

1. Measurement values
Serve to display the current measured temperatures.
If ‚error‘ appears on the display instead of the measurement value,
there may be a defective or incorrect temperature sensor.
If the cables are too long or the sensors are not well-placed, small devi-
ations in the measurement values may occur. In this case, the display
values can be compensated by adjustments in the controller See "
Sensor Calibration " on page 42. The selected program, connected
sensors and the specific model design determine which measurement
values are displayed.
29
2. Statistics
Serve for function control and long-term monitoring of the system.
For time-dependent functions such as circulation and anti-legionella and
the evaluation of system data, it is essential that the time is accurately set
on the controller. Please note that the clock continues to run for about 24
hours if the mains voltage is interrupted, and afterward must be reset.
Improper operation or an incorrect time may result in data being cleared,
recorded incorrectly or overwritten. The manufacturer accepts no liability
for the recorded data!

Operating mode
Heating: automatic/normal operation taking into account operating times (day, comfort increase, night reduction).
Reference: fixed flow temperature independent of the outside temperature. The desired flow temperature must be set in Menu 5.1.5. .
Reference program: e.g. for screed heating. For the next 14 days, can be found under Menu 4. different fixed flow temperatures can be
entered. After 14 days, the reference temperature of the 14th day is used continuously until the operating mode is changed. Different tem-
perature values can be set in menu 5.4. for every individual day separately.
Set room controllers have no influence on the setpoint program!
Heating and cooling: automatic/normal operation taking into account operating times (day, comfort increase, night decrease) with
change of season.
The operating mode can be changed from heating to cooling in different ways:
1. Switching via °CALEON Clima room controller
a. Configuration "See " °CALEON Room Controllers " on page 24"
b. Main menu °CALEON Clima room controller
2. Using a sensor input for the change of season (e.g. by signal of an invertible heat pump or via an external switch). The sensor
input is monitored for short circuit (closed= cooling, open = heating).
a. menu 5. Settings - > Heating Circuit (X) - > Room Contr. heating circ. (X) -> Thermostat -> Sensor Input (e.g., S1)
b. Menu 5. Settings -> Heating Circuit (X) -> Thermostat -> Sensor Type -> Season

Season switch
Only appears, if "heating and cooling" mode is selected. Heating circuits separately, or switching system-wide between heating and cooling.
S/W Day
Summer / Winter changeover in daytime mode
If this value is exceeded at the outdoor sensor the controller automatically switches the heating circuit off = Summer mode. If the outdoor tem-
perature drops below this value, the heating circuit is switched on again = Winter mode.
In addition to the operating times in normal daytime operation, this setting is also valid for times with activated comfort.
S/W Night
Summer/Winter changeover in night-time mode
If this value is exceeded at outdoor sensor S1 during the nighttime mode times, the controller automatically switches the heating circuit off =
Summer mode. If the outdoor temperature drops below this value, the heating circuit is switched on again = Winter mode.
Curve
Type and slope of the heating characteristic curve
The characteristic curve is used to control the heat dissipation of the heating circuit relative to the outdoor temperature. The demand for heat
differs due to factors such as the type of building, heating, insulation and outdoor temperature. For this reason, the controller can operate with
a normal straight curve (setting ‚simple‘) or split curve (setting ‚split‘).
If ‚simple‘ is selected, the curve is adjusted using the graphic diagram. While setting the slope, the controller also shows the slope value and
the calculated target flow temperature at -12 °C as a reference point.
If ‚split is selected, the curve is set in the following steps:
1. Outdoor temperature for slope change
2. Slope over outdoor temperature for change
3. Slope below outdoor temperature for change
While setting the slope, the controller also shows the slope value and the calculated target flow temperature at -12 °C as a reference point. In
case of repeated adjustment of the split curve, the settings appear in reverse order.
The diagram shows the influence of the selected characteristic curve steepness
(standard curve) on the calculated reference flow
temperature of the heating unit. The correct characteristic curve is determined by
defining the intersection point of the maximal calculated flow temperature (=design
temperature) at minimal outdoor temperature.
Example: The design temperature of the heater 60 °C flow at lowest outdoor tem-
perature according to calculation of heat requirement
-12 °C. The intersection point renders a slope of 1.2 as the setting.
Day Correction
Parallel characteristic translation
The day correction causes a parallel shift of the heating curve during daytime operating hours, because with certain outdoor temperatures the
building might not be optimally heated with the set heating curve. With a non-optimised heating curve, the following situations frequently
occur: hot weather = room too cold/cold weather = room too hot. In this case, the slope of the curve should be reduced stepwise by 0.2 points
and increases the day correction
by 2 ... 4 °C each.
Night Correction
Parallel characteristic translation
The night correction produces a parallel translation of the heating characteristic during the nighttime operating hours. If a negative value is set
for the night correction, the reference flow temperature is lowered accordingly during the nighttime operating hours. In this manner, primarily
34
at night, but also during the day when no-one is at home, the room temperature is lowered, thus saving energy. Example: A day correction
of +5 °C and a night correction of -2 °C produces a reference flow temperature in nighttime operation that is 7 °C lower.
Comfort Temperature Boost
Parallel characteristic translation
The comfort temperature boost is added to the set day correction. In this manner it is possible to carry out quick heating and/or raise the
temperature of living spaces at a certain time each day.
Min. Flow
The minimum flow temperature is the lower limit of the heating curve, and by this, the reference flow temperature of the heating circuit. In
addition to that, the minimal flow temperature is the reference flow temperature for the frost protection function.
Max. Flow
This value is the upper limit of the reference flow temperature of the heating circuit If however, the temperature of the heating circuit
exceeds the set value, the heat circuit shuts down until the temperature falls below this value. After 55 seconds, rinse for 5 seconds.
The customer must provide an additional limiting thermostat which is connected to the pumps in series (eg underfloor heating)
for safety.
Reference/Actual -
Switch on hysteresis for additional heating
This setting determines the allowed undershoot of the heating circuit temperature below the calculated reference fl ow temperature. If the
heating circuit flow temperature and the storage temperature drop below the reference flow temperature by this value, the additional heat-
ing will start the additional heat source after a 1 minute delay.
Heat request is started when the flow temperature is continuously below reference temperature for 1 minute.
Reference/Actual +
This value determines the acceptable underflow of the heating circuit temperature beyond the calculated reference flow temperature at the
buffer sensor or flow sensor. If the temperature at the buffer sensor exceeds the reference flow temperature by the value set here, the heat-
ing request is deactivated.
The setting value reference/actual + appears only in the menu if a sensor has been set under buffer sensor.
Variant
Only appears, if the heating circuit is an unmixed heating circuit (no mixer 1).
The condition for switching off the heating circuit pump is set. In the mode flow (FL), the pump is shut down, if the reference temperature is
exceeded. In the summer/winter mode (SW), it is shut down in the winter mode at Tmax, in the summer mode the heating circuit pump is
shut down in general.
The sensor should be placed in the return line in the VL mode.
Heating circuit off
If you use a room controller, the heating circuit can also be switched off on the base of the room controller in addition to the switch-off
according to outside temperature.
Summer: Heating circuit turns off when the summer/winter time changeover (outside temperature) is exceeded.
Summer + Room: Heating circuit is turned off as soon as the summer/winter time changeover (outside temperature) or the room setpoint
temperatures are exceeded.
Room hysteresis
Only appears, if "Switch off heating circuit" has been set to "Summer+Room". If the reference room temperature + the hysteresis set here
are exceeded, the heating circuit is switched off.
35
In cooling mode, reactivation when the room temperature is exceeded.
Buffer sensor
Input of heating circuit buffer sensor.
In this menu, the sensor is set, which is used as a reference sensor for the heating circuit request. Switching on and off conditions for a heat-
ing circuit request See " Reference/Actual - " on page 35 / See " Reference/Actual + " on page 35.
The request only works if an energy source (burner, compressor, solid chamber) is activated as an additional function and if this

Burner: See " Heating Circuit request " on page 54,
Compressor: See " HC request " on page 55,
Heater: See " HC request " on page 50).
Insulation factor
Depending on the selected factor, the outdoor temperature has an influence on the VL temperature calculation after the set delay.
0= Off, 1= 15 minutes, 2= 60 minutes, 3= 120 minutes, 4= 300 minutes
Better insulated buildings can increase comfort and save energy by increasing the building factor.
Overload protection
If the function is set to "On", it does not matter which state the heating circuit has. If the temperature at the buffer sensor is above Max. buffer,
the heating circuit pump switches on and the setpoint flow rate is fixed to See " Max. Flow " on page 35 -2°C or the adjusted set point. If the
set Max. If the temperature of the buffer falls below 5 Kelvin, the heating circuit switches back to the previous mode.
Min. Flow cooling
Only appears when the operating mode of the heating circuit is set to heating and cooling or cooling.
This value is the upper limit of the reference flow temperature of the cooling.
Max. flow cooling
Only appears when the operating mode of the heating circuit is set to heating and cooling or cooling.
This value is the upper limit of the reference flow temperature of the cooling.
Dew Point protection
Only appears, if the operating mode of the heating circuit is set to heating and cooling or cooling.
Is only active, if humidity is measured (e.g. via a °CALEON Clima room controller). It is calculated from which room temperature there is
unwanted condensation (precipitation) for the currently measured humidity. Dew point monitoring automatically shifts the target supply tem-
perature in cooling mode to prevent mould formation.
Dew point correction
Only appears, if the operating mode of the heating circuit is set to heating and cooling or cooling. This value moves the internal dew point
characteristic by up to 10 °C in parallel.
Example 1: You determine that there is condensation with the default value, so you increase this correction value.
Example 2: Condensation/precipitation can be ignored, but stronger cooling is required instead. You therefore decrease this correction
value.
In case of reduction of the calculated temperature with the help of dew point correction condensation / perspiration / precipitation
can occur, which, among other things, may cause the formation of mold.
Room Controller Heating Circuit (X)
Here, the settings are made for an optional room controller. The following variants can be used with different functions:
°CALEON Room Controller:
36
Influence of the room temperature, the room reference temperature as well as of room-specific time programs on the reference flow. Oper-
ating modes of the °CALEON and significance for the HCC:
Off = Heating Circuit Off,
Eco = Reference - Night reduction,
Normal = Reference + daily correction,
Comfort = Reference + daily correction + comfort increase
The selection of an operating mode (Normal, Comfort, Eco or Off) is only valid until a change to another mode is effected in the
time program of the °CALEON.
Example: The operating mode “Off” is activated on the °CALEON. The next change in the time program ends the manually set
operating mode and activates the mode set according to the time program. If a longer shutdown of the heating circuit is
desired, for example, the holiday mode can be used in the °CALEON.
If several °CALEONs are set as room controllers, the operating mode of the HCC is determined by the room with the greatest
energy demand.
RC21:
Influence of the room temperature on the reference, parallel shift of the characteristic curve by the control dial, influence on the reference
flow by the operating mode switch. Operating modes of the RC21 (Switch) and significance for the HCC:
Auto = Set reference,
Day = Reference + daily correction,
Night = Reference night reduction
For detailed instructions on how to connect °CALEON or an RC21, See " °CALEON Room Controllers " on page 24
Sensor input (S1-S6, VT1, VT2):
Use of a sensor input as room controller with different functions (see "Sensor Type").
Set room controllers have no influence on the setpoint program!
Thermostat (X)
The room controller or sensor input is selected here.
When using a °CALEON: select the room set in the °CALEON.
When using an RC21: select RC21-Local 1 and then select RC 1 Temp. 1 and RC1 Contr. sensor inputs used - See " RC21 Room ther-
mostat with remote control " on page 26.

Season: Closed= cooling, Open = heating
RC 1 Temp. 1
Only appears, if an RC21 has been set in "Thermostat (X)".
Select here the sensor input that you use for the temperature sensor (Terminal 1) of the RC21.
RC 1 contr.
Only appears, if an RC21 has been set in "Thermostat (X)".
Select here the sensor input that you use for the remote control (Terminal 2) of the RC21.
37
Room Controller
This value is used to appoint the amount of influence the room temperature has on the reference flow temperature, as a percentage. For each
degree deviation between room temperature and set point temperature, the percentage set here is added from the calculated set flow tem-
perature to the set flow temperature or subtracted from it until the min. or max flow values.
Example: Reference room temp.: e.g. 25 °C; room temp.: e.g. 20 °C ±5 °C. Calculated reference temp.: e.g. 40 °C: room controller: 10 %= 4
°C 5 X 4 °C= 20 °C. Accordingly, 20 °C are added to the reference flow temperature, giving 60 °C. If the value is higher than the one set in
max. flow temp, the resulting temperature is the one set in max. flow temp.
Room Reference Day
The desired room temperature for day mode.
In combination with the %-value set under "room controller", the difference between reference and actual room temperature influences the
reference flow temperature. If the room controller is set to 0 %, this function is deactivated.
For °CALEON room controller without influence.
Room Reference Night
The desired room temperature for night mode.
In combination with the %-value set under "room controller", the difference between reference and actual room temperature influences the
reference flow temperature. If the room controller is set to 0 %, this function is deactivated.
For °CALEON room controller without influence.
In the mode Set point program, the room controller has no influence.
Smart grid 1/ PV contact
A sensor input can be set here, which can be used as Smart grid terminal 1 for interference by the energy supplier or as a PV contact for a
photovoltaic system. This sensor is observed to "short circuit" (PV-Contact closed). If the PV-Contact is closed, the mode of this function is
changed to "comfort" and operated at the comfort temperature set for the comfort function. This also applies in the case that the mode "com-
fort" of the function currently has no time release.
Information about the operation and the connection of PV-contact, refer to the technical description of your PV system.
Smart grid 2
Smart Grid Terminal 2 for influence by the energy supplier. The inputs are checked for open and short-circuit. The combination of inputs 1
and 2 determines how the heating circuit is influenced: 1= short-circuit, 0 = open Terminal 1: Terminal 2
0:0 = Set heating circuit modes to "Off".
1:0 = Set heating circuit modes to" Eco
0:1 = Set heating circuit mode according to time and room controller settings
1:1= Set heating circuit mode to "Comfort" mode
Settings Domestic Hot Water (DHW)
By no means does the controller replace the safety appliances on site!
Operating mode
The DHW heating can be set here. “Auto” activates the DHW heating according to the time program, with “off” the DHW heating is turned off.
Hot water minimum
Minimum DHW temperature. If the set temperature at the DHW sensor is undeshot outside of the set times, the DHW charge and heat
request will be turned on.
DHW reference
Minimum DHW temperature time program. If the set temperature at the DHW sensor is undershot and the DHW charge is approved for the
time, the DHW charge and the heat request will be turned on.
38
The request only works if an energy source (burner, compressor, solid chamber) is activated as an additional function and if
this source is set for the DHW request.
DHW comfort
DHW temperature for comfort time. The set temperature considered as minimum temperature during the set comfort time. If the tem-
perature on DHW-sensor is below the value set here is during the DHW comfort periods, the DHW heating is started, until DHW comfort +
hysteresis is achieved.
DHW hysteresis
DHW hysteresis. The DHW charge and heat request are shut down if the temperature at the DHW sensor reaches the value set under “See
" Hot water minimum " on page 38“ / “See " DHW reference " on page 38“ plus the heating set here.
Buffer DHW load
DHW load from the buffer. The DHW load from the buffer storage is turned on if the temperature on the buffer sensor is at least 8 °C
warmer than at the DHW sensor. The DHW load from the buffer storage is shut down if the temperautre at the buffer sensor is only 4 °C
warmer than at the DHW sensor or if the temperature at the DHW sensor has reached the value set under See " Hot water minimum " on
page 38 or See " DHW reference " on page 38.
DHW priority
Preferred DHW charge. If this function is activated, the reference flow temperature during a DHW heating will be set to the minimum flow
temperature See " Min. Flow " on page 35 so that the mixer moves to the “closed” position.
DHW sensor
The sensor used as a domestic hot water sensor.
Smart grid 1/ PV contact
A sensor input can be set here, which can be used as Smart grid terminal 1 for interference by the energy supplier or as a PV contact for a
photovoltaic system. This sensor is observed to "short circuit" (PV-Contact closed). If the PV-Contact is closed, the mode of this function is
changed to "comfort" and operated at the comfort temperature set for the comfort function. This also applies in the case that the mode "com-
fort" of the function currently has no time release.
Information about the operation and the connection of PV-contact, refer to the technical description of your PV system.
6. Protective Functions
The 'Protective functions‘ can be used by specialists to activate and set various pro-
tective functions.
By no means does the controller replace the safety appliances on site!
Seizing Protection
If the anti-seizing protection is activated (daily, weekly, off), the controller switches the outputs on/off at 12:00 noon for 5 seconds to prevent
seizing of the pump/valve after long periods of inactivity.
Frost Protection
If the external temperature on sensor S1 goes below 1 °C and the heating circuit is turned off, the heating circuit will automatically be turned
on if the frost protection is activated and the reference flow temperature is set at the minimum flow temperature set under See " Min. Flow "
on page 35. As soon as the outdoor temperature exceeds 1 ° C, the heat circuit is switched off again.
Switching the frost protection function off or setting the minimum flow temperature too low can lead to severe damage to the sys-
tem.
39
Discharge Protection
With activated buffer discharge protection, the heating circuit is switched off as soon as the buffer temperature undershoots the min. flow tem-
perature. flow temperature. Every 5 minutes, the system checks if the flow temperature has been reached.
Dew point correction
Activate or deactivate. Activated dew point correction corrects the heating circuit flow temperature in cooling mode and switches off the heat-
ing circuit when the temperature falls below the dew point in order to prevent condensation.
Pressure Monitoring
In this menu, the system pressure monitoring can be activated through a direct sensor. A message is displayed and the LED flashes red
when the pressure drops below minimum or exceeds the maximum.
RPS1 / RPS2
In this menu, you can adjust which pressure sensor model is being used. Please note: If e.g. VFS1
is connected, RPS1 will be hidden
RPS Min
Minimum pressure. If this pressure is not met, the controller emits an error notification and the red LED flashes.
RPS Max
Maximum pressure in the system. If this pressure is exceeded, the controller emits an error message and the red LED flashes.
Protective functions for Solar
The protection functions for Solar are not displayed in the “Protective functions” menu, but rather as a sub-menu in the settings
from the solar function, See " Solar " on page 52.
System protection
Priority protection function
The system protection should prevent an overheating of the components installed in the system through the forced shut down of the solar cir-
culation pump. If the value “AS Ton” on the collector has been exceeded for 1 Min. the pump will be turned off and not turn on again in order to
protect the collector, for example, from steam. The pump will only be switched on again, when the collector temperature falls below “SP Toff”.
With the system protection (on), there are increased standstill temperatures in the solar collector and therefore an increased pres-
sure in the system. The operating manuals from the system components must be observed.
Collector protection
Priority protection function
The collector protection prevents the collector from overheating. A forced switching of the pump makes sure that the collector is cooled
through the storage. If the value “KS Ton” is exceeded on the collector, the pump will be turned on in order to cool the collector. The pump is
shut down if the value “KS Toff” on the collector is not met or the value “KS Tmax Sp.” on the storage is exceeded.
System protection has priority over collector protection! Even if the switch requirements for the collector protection are present,
the solar circulation pump is turned off once “AS T on” is reached. Normally the values from the system protection (depending on
the maximum temperature of the storage or other components) are higher than the collector protection.
Recooling
In the system hydraulics with solar, excess energy is guided from the storage back to the collector with an activated return cooling function.
This only occurs if the temperature in the storage is greater than the value “Return cooling Tref” and the collector is at least 20 °C colder than
the storage and until the storage temperature has fallen below the value “Return cooling Tref”. For muti-storage systems, the return cooling
applies to all storage.
Energy is lost through the collector through this function! The recooling should only be activated in cases of exception, with low
heat acceptance, for example, during vacation.
40
Frost Protection
A 2-level frost protection function can be activated. In level 1, the controller turns on the pump every hour for 1 minute if the collector tem-
perature is below the set value “Frost Level 1”. If the collector temperature continues to decrease to the set value “Frost Level 2”, the con-
troller will turn on the pump without disruption. If the collector temperature exceeds the value “Frost level 2” by 2 °C, the pump will turn off
again.
Energy is lost through the collector through this function! It is normally not activated for solar systems with antifreeze. The oper-
ating manuals from the other system components must be observed.
Collector alarm
If this temperature at the collector sensor is exceeded when the solar pump is turned on, a warning or error notification is triggered. There is
a corresponding warning in the display.
7. Special Functions
Used to set basic items and expanded functions.
The settings in this menu should only be changed by a specialist.
Program selection
Here the hydraulic variation fitting to the respective use case is selected and set.
The program selection normally occurs only once during the first entry into service by a specialist. An incorrect program selec-
tion may lead to unpredictable errors.
Pump settings V(X)
Settings from the 0-10V or the PWM pump can be made in this menu.
When this menu is selected, you may receive a request to save the speed settings.
Signal type
Only available, if the function is used on one of the V-outputs. The type of device to be controlled is set here.
0-10V: Control by 0-10V signal.
PWM: Control by means of a PWM signal.
Profile
In this menu, the preset profiles for actuators can be selected or under “manual” all settings can be done personally. The settings can still
be changed after a profile has been selected.
Output Signal
In this menu the type of actors are set: heating pumps have the greatest output with a small input signal, solar pumps in contrast have very
little output with a small input signal. Solar = normal, heating = inverted.
PWM / 0-10V off
This signal / this voltage is emitted if the actor is turned off (actor with cable break detection require a minimum voltage / a minimum signal).
PWM / 0-10V on
This voltage / this signal requires the pump in order to turn on and to run at a minimum speed.
41
PWM / 0-10V max.
With this value, the maximum signal / maximum voltage level can be specified for the highest speed of the energy saving valve, which is
used, for example, during the purging or manual operation.
Show signal
Represents the set signal in a graphic and text overview.
Speed control
If the speed control is activated, it LHCC offers the possibility through a special internal electronic system to change the speed of pumps
depending on the process. The PWM and 0-10V outputs can work speed-controlled.
Variant
The following speed variants are available here:
Off: There is no speed regulation. The connected pump is only turned on or off with full speed.
Mode M1: The controller changes to the set max. speed after the purging time. If the temperature difference ∆T between the reference
sensors is below the set switch on temperature difference ∆T R1, the speed will be reduced. If the temperature difference between the ref-
erence sensors is above the set switch on temperature difference ∆T R1, the speed will be increased. If the controller has decreased the
speed of the pump to the smallest level and the ∆T between the reference sensors is still only ∆Toff, the pump will be turned off.
Mode M2: The controller changes to the set min. speed after the Speed. If the temperature difference ∆T between the reference sensors is
above the set switch on temperature difference ∆T R1, the speed will be increased. If the temperature difference ∆T between the reference
sensors is below the set switch on temperature difference ∆T R1, the speed will be reduced. If the controller has decreased the speed of the
pump to the smallest level and the ∆T between the reference sensors is still only ∆Toff, the pump will be turned off.
Mode M3: The controller changes to the set min. speed after the Speed. If the temperature on the reference sensors is above the set value to
be set in the following, the speed will be increased. If the temperature on the reference sensors is below the set value to be set in the fol-
lowing, the speed will be reduced.
Purging time
For this time, the pump runs with its full speed (100%) in order to guarantee a secure start-up. Only after expiration of this purging time will the
pump have a controlled speed and will switch, depending on the set variant, to the max. or min. speed. Speed.
Sweep time
With the control time, the inertia of the speed control is determined in order to prevent strong temperature deviations as much as possible.
The timespan is entered here, which is needed for a complete cycle from minimum speed to maximum speed.
Max. Speed
The maximum speed of the pump is determined here in %. During the setting, the pump runs in the respective speed and the flow can be
determined.
The specified percentages are variables, which may deviate more or less strongly depending on the system, pump and pump
level. 100% is the maximum possible power of the controller.
Min. Speed
The minimum speed of the pump is determined here. During the setting, the pump runs in the respective speed and the flow can be determ-
ined.
The specified percentages are variables, which may deviate more or less strongly depending on the system, pump and pump
level. 100% is the maximum possible power of the controller.
Setpoint
This value is the control setpoint. If this value is below at the sensor, the speed is reduced. When it is exceeded, the speed is increased.
Sensor Calibration
Deviations in the temperature values displayed, for example. due to cables which are too long or sensors which are not positioned optimally
can be compensated for manually here. The settings can be made for each individual sensor in steps of 0.5 °C.
Settings are only necessary in special cases at the time of initial commissioning by the specialist. Incorrect measurement values
42
can lead to unpredictable errors.
Relay functions
Free relays, i.e. relays not used in a basic scheme, can be assigned to various additional functions. Every additional function can only be
assigned once. Preset functions can be deselected. See " Function overview " on page 47
When assigning relays with functions, the activated function for already used relays must first be deactivated before a new
function can be selected.
R1 to R3: mechanical relay 230V
R1 to R4: mechanical relay 230V
V1 and V2: PWM and 0-10 V outputs See " External relay at signal output V(X) (0-10V / PWM) " on page 13
Please pay special attention to the relay’s technical information (see "Specifications“).
The symbols shown here are displayed on the main overview screen when the special function is activated.
Heat quantity
Constant flow
If “Constant flow” is activated as the type of heat quantity metering, the approximate heat from the manually entered values for antifreeze,
its concentration and the flow from the system and the measured sensor values from the collector and storage are calculated. Additional
information about antifreeze, its concentration and the flow of the system is required. Additionally through the setting offset ∆T, a correction
factor can be set for the heat quantity collection. Since the collector temperature and the storage temperature can be used for the heat
quantity metering, depending on the system, there may be deviations from the displayed collected temperature to the actual previous tem-
perature or the displayed storage temperature to the actual return temperature. Through the setting Offset ∆T, this deviation can be cor-
rected.
Example: displayed collector temperature 40°C, read previous temperature 39°C, displayed storage temperature 30°C, read return tem-
perature 31° means a setting of -20% (displayed ∆T 10K, actual ∆T 8K => -20% correction value)
The heat quantity data in the “Constant flow” mode only consists of calculated values for the functional inspection of the system.
Flow temperature sensor (X)
In this menu, it is set which sensor is used to measure the flow temperature.
Return flow sensor
In this menu, you can set which sensor is used to measure the return flow temperature.
Glycol type
In this menu, the antifreeze used is set. If none is used, please set glycol proportion to 0.
Glycol percentage
The percentage of antifreeze in the medium.
Flow rate supply flow (X)
Nominal system flow.
The flow of the system in liters per minute, which is used as calculation basis for heat metering.
Offset ∆T
Correction factor for the temperature difference for heat metering
Since the collector temperature and the storage temperature can be used for the heat quantity metering, depending on the system, there
may be deviations from the displayed collected temperature to the actual previous temperature or the displayed storage temperature to the
actual return temperature. This deviation can be corrected with the adjustment value Offset ΔT
Example: displayed collector temperature 40°C, read previous temperature 39°C, displayed storage temperature 30°C, read return tem-
perature 31° means a setting of -20% (displayed ∆T 10K, actual ∆T 8K => -20% correction value)
VFS (X)
The type used of direct sensor is set in this menu.
43
VFS - Position
This menu is used to set whether the direct sensor was mounted in supply or return flow.
To prevent damage to the Vortex Flow sensor it is highly recommended to place it in the return flow. If contrary to this recom-
mendation it is used in the supply line, the maximum temperature has to be considered. (0 ° C to 100 ° C continuous operation
and short term -25 ° C to 120 ° C)
Reference sensor
The sensor to be used for heat metering is set here.
Commissioning
Starting commissioning help guides you in the correct order through the basic settings necessary for commissioning, and provides brief
descriptions of each parameter in the display. Pressing the ‚esc‘ key takes you back to the previous value so you can look at the selected set-
ting again or adjust it if desired. Pressing ‚esc‘ more than once takes you back to the selection mode, thus cancelling the commissioning help
(See " Commissioning help " on page 29).
May only be started by a specialist during commissioning! Observe the explanations for the individual parameters in these instruc-
tions, and check whether further settings are necessary for your application.
Factory Settings
All settings can be reset, returning the controller to its delivery state.
All of the controller‘s parametrization, statistics, etc. will be lost irrevocably. The controller must then be commissioned once
again.
Eco Display Mode
In Eco Display Mode the backlight of the display is switched off if no buttons are pushed for 2 minutes.
If a message exists, the backlight does not switch off until the message has been scanned by the user.
Network
If necessary, the network settings of the connected data logger must be set.
Access Control
This menu lets you give up to 4 users access to the data logger. The users that are registered then have access to the controller or respect-
ively the data logger.
To add a user in the list, select <add user>. Leave the now visible menu open und connect to the address of the connector or respectively the
data logger. Your user name is going to appear in this menu and can be selected and confirmed with ‘OK’.
Note
You can find the address of the connector or respectively the data logger on the address sticker on the outside of the casing. Pointers and
help on how to establish a connection you can find in the enclosed SOREL Connect instructions or the instructions of the data logger.
Select a user with ‚OK‘ to grant access.
To revoke access again, choose one of the users from your list and choose <remove user>.
Ethernet
The data logger‘s Ethernet connection settings can be set using this menu.

Function overview
When assigning relays with functions, the activated function for already used relays must first be deactivated before a new
function can be selected.
Mixer
This menu contains all settings relating to the mixer of the heating circuit.
Direction
Direction of the mixing valve can be set here.
Mixer turn time
The mixer is switched on i.e. is opening or closing for the time span set here, then the temperature is measured to control the flow tem-
perature
Mixer off factor
The calculated pause time of the mixer is multiplied with the value set here. If the pause factor is ‚1‘, the normal pause time is used, ‚0.5‘ will
use half the normal pause time. Setting the pause factor to ‚4‘ would quadruple the pause time.
Mixer increase
If the temperature rises very fast, this value is added to the measured flow temperature so that the mixer’s reaction is stronger. If the meas-
ured temperature does not rise any more, the measured value is used again. The measurement occurs once every minute.
Mixer run time
Mixer-specific setting of the running time required by the mixer for a full ride.
Signal type
Only available, if the function is used on one of the V-outputs. The type of device to be controlled is set here.
0-10V: Control by 0-10V signal.
PWM: Control by means of a PWM signal.
Cooling valve Heating circuit 1/ Heating circuit 2
If the heating circuit is in heating-off, cooling-off, heating-eco, heating-normal or heating-comfort mode, the relay is switched off or switched
to the heating circuit buffer.
If the heating circuit is in cooling-Eco, cooling-normal or cooling-Comfort mode, the relay is switched on or the valve switches to the cooling
circuit.
The additional function cooling valve heating circuit 1 / heating circuit 2 is only visible if heating circuit 1 / 2 has been activated
on an output.
Heating Circuit 2
See " Heating Circuit (X) " on page 33
Free Cooling
If the function is activated, the output switches a pump or fan and supplies the heating system with "free cooling". This pump supplies e.g.
heating circuits whose cooling valve is switched on and must therefore run as soon as cooling is required in at least one heating circuit.
Switch-on condition: a heating circuit is set to Cooling-Eco, Cooling-Normal or Cooling-Turbo.
Switch-off condition: no heating circuit cools.
47
RFI mixer
The RLA-mixer function (return flow increase mixer) can be used to control a motorized return flow increase for a solid fuel boiler or a return
flow buffer/buffer admixture. The RFI mixer requires either 2 relay switch outputs (230) or alternatively may be controlled via a 0-10V / PWM
output (PWM mixer).
Operating mode
The RFI mixer can be operated in "SF increase" (solid fuel boiler), "setpoint" or "heating circuit automatic" mode.
SF increase: motorized return flow increase for a solid fuel boiler.
Heating circuit automatic: the setpoint temperature, which is provided by the RFI mixer at the flow sensor, is specified by the heating circuit
1. In addition, a target flow offset can be set.
Setpoint: The setpoint temperature, which is provided by the RFI mixer at the flow sensor, will be set fixed under see "Tsoll".
Reference flow sensor
Sensor for monitoring the reference variable of the RFI function. The mixed temperature of the RFI mixer is measured at this sensor and com-
pared with the current setpoint value. If the flow rate falls below or exceeds this limit, the mixer is controlled or controlled accordingly.
Tref:
Temperature controlled by the mixer.
For operating mode solid fuel boiler
When using a motorised return temperature control for a solid fuel boiler, the minimum temperature of
it should not fall below the return (Tref) of the solid fuel boiler. Please refer to the boiler manufacturer's

Season switch
1. 2.
1. Mode "Heating" -> output of the season switch is not active
2. Mode "Cooling" -> output of the season switch active
The seasonal switch function switches for change of season (from heating to cooling or vice versa) in combination with the energy request.
For example, for inverting a heat pump suitable for reversible operation. If the request for domestic water is activated for the heat pump in
the controller, the operating mode of the heat pump automatically switches to the "heating" mode in case of domestic water request, i.e. the
output of the seasonal switch is switched off.
Off hysteresis
If the controller has changed the season from cooling to heating and flow <reference flow + Off hysteresis, the seasonal switch will be
switched off (output not switched).
Example 1:
Flow = 28 °C; target flow = 30 °C; off-hysteresis = - 3 °C
28 °C < 30 °C - 3 °C -> 28 °C < 27 °C -> wrong! -> Do not switch off the season change
51
Example 2:
Flow = 28 °C; target flow = 30 °C; off-hysteresis = + 3 °C
28 °C < 30 °C + 3 °C -> 28 °C < 33 °C -> correct! -> Switch off the season change
On hysteresis
If the controller has changed the season from heating to cooling and flow <reference flow + On hysteresis, the seasonal switch will be
switched on (output switched).

Solid fuel boiler
In solid-fuel boiler function, a pump is controlled with a assigned relay, which loads the heat energy from a solid-fuel boiler into a storage tank.
The solid-fuel boiler function controls the charge pump of a solid-fuel boiler based on the temperature difference between the solid-fuel boiler
sensor and the storage tank sensor.
If a control output (V1 or V2, ...) is used with this function, a speed control with a PWM / 0-10V HE pump is possible.
Solid fuel boiler Tmax
Maximum temperature in storage tank. If this is exceeded, the relay is switched off.
Solid fuel boiler Tmin

ditions are met.
Below the solids boiler Tmin temperature, the solids boiler function is deactivated.
ΔT Solid fuel boiler
Switch-on and switch-off difference between solid fuel boiler (SFB) and storage tank.
If the temperature difference between the sensors defined for this function exceeds the value set here (ΔT SF On), the function switches on
the assigned output (relay or signal output).
If the set temperature difference (ΔT SF Off) between the solids boiler and the storage tank is below, the function switches off the assigned
output (relay or signal output).

valve. If the temperature on the sensor falls 5 °C below this value, the pump or the valve will be turned off again.
52
ΔT Solar
Switch on/switch off temperature difference for sensor X:
If the temperature difference ΔT Solar between the reference sensors is exceeded and the other conditions are fulfilled, the controller will
turn on the pump/valve on the corresponding relay. If the temperature difference falls to ΔT Off, the pump/valve will be turned off again.
Tmax Storage
Switch off temperature at sensor X:
If this value is exceeded at the specified sensor, the controller turn off the affiliated pump or the valve. If this value on the sensor is under-
shot and the other conditions are fulfilled, the controller will turn on the pump or the valve.
Temperature values which are set too high can lead to scalding or damage to the system. Scalding protection must be provided
by the customer!
Starting aid
For some solar systems, in particular for vacuum tube collectors, the measurement recording on the collector sensors may be too slow or
imprecise, because the sensor is often not on the warmest spot. With an activated starting aid, the following procedure occurs: If the tem-
perature on the collector sensor increases within a minute by the value defined under “increase”, the solar circulation pump will be turned
on for the set “purging time” so that the medium to be measured is transported to the collector sensor. If there is still no normal switching
condition through this, there will be a 5 minute block time for the start wizard function.
This function should only be activated by a technician if problems occur with the measurement recording. Observe in particular
the instructions from the collector manufacturer.
The menus "Purging time" and "Increase" are only displayed when the starting aid function is set to "On".
Purging time
If the temperature on the collector sensor increases within a minute by the value defined under “increase”, the solar circulation pump will be
turned on for the set “purging time” so that the medium to be measured is transported to the collector sensor. If the set ΔT is not reached, a
5-minute circulation pause time for the starting aid function will apply.
Increase
If the temperature at the collector reaches within a minute the value defined, the solar pump is turned on for the duration of the purging
time.

Malfunctions/Maintenance
Replacing the Fuse
Repairs and maintenance may only be performed by a specialist. Before working on the unit, switch off the power supply and
secure it against being switched on again! Check that there is no power flowing!
Only use the included safeguard or a similar safeguard with the following
specifications: T2A / 250 V.
If the mains voltage is switched on and the controller still does not function or display anything,
then the internal device fuse may be defective. First find the external fault source (e.g. pump),
replace it and then check the device fuse.
To replace the device fuse, open the device as described under "See " Wall Installation " on page
11", remove the old fuse, check it and replace if necessary.
Then first recommission the controller and check the function of the switch outputs in manual mode
as described in Section 4.1.
Maintenance
In the course of the general annual maintenance of your heating system, the functions of the controller should also checked by
a specialist and the settings should be optimized if necessary.
Performing maintenance:
lCheck the date and time See " Time & Date " on page 31
lAssess/check plausibility of statistics See " Statistics " on page 30
lCheck the error memory See " Notifications " on page 30
lVerify/check plausibility of the current measurement values See " Measurement values " on page 29
lCheck the switch outputs/consumers in manual mode See " Manual " on page 32
lPossible optimization of the parameters setting (only on customers request)

Tips
The service values include not only current measurement values and operating states, but also all of the settings for the controller.
Write the service values down just once after commissioning has been successfully completed.
In the event of uncertainty as to the control response or malfunctions the service values are a proven and successful method for
remote diagnosis. Write the service values down at the time that the suspected malfunction occurs. Send the service value table by
fax or e-mail with a brief description of the error to the specialist or manufacturer.
To protect against loss of data, record any statistics and data of particular importance at regular intervals.
Support Guideline
If there are errors with your device, please proceed as follows:
1. Read user manual
2. Check FAQ
3. Watch help-video on YouTube
4. Talk to an installation technician/tradesman

Signal
In this menu, the preset profiles for the signal can be selected or under “manual” all settings can be done personally. The settings can still be
changed after a profile has been selected.
Output Signal
In this menu the type of actors are set: heating pumps have the greatest output with a small input signal, solar pumps in contrast have very
little output with a small input signal. Solar = normal, heating = inverted. For 0-10 V pump always choose the "Normal" setting
PWM / 0-10V off
This voltage / this signal is emitted if the actor is turned off (actor with cable break detection require a minimum voltage / a minimum signal).
PWM / 0-10V on
This voltage / signal is required the actuator to switch on and run at minimum speed.
62
PWM / 0-10V max.
With this value, the maximum voltage level / maximum signal can be specified for the highest speed of the actuator, which is used, for
example, during the purging or manual operation.
Speed when „On“
In this menu, the calculation basis of the displayed speed is changed. If, for example, 30% is specified here, the signal/voltage set under
“PWM On” / “0-10V On” will be displayed during creation so that a 30% speed is present. When creating the signal/voltage of PWM Max / 0-
10V Max, 100% speed is displayed. Temporary values are calculated correspondingly.
This function does not influence the rule, but rather only the display on the status screen.
