1. Application



ClimaticControl-HC is developed for variable flow temperature control in heating and cooling systems particular

in low-temperature installations like floor heating and cooling systems. The flow temperature is controlled de-

pending of the outside temperature following a curve.



Using the ClimaticControl-HC the operation of a water floor system can be adapted to the actual demands of the

system. In particular, the control can be used in apartments where users have their own individual living habits.

A room temperature thermostat can also be connected. The control has a 7-day programmer including 9 factory

set programs and 4 user defined programs.



The control is normally used in conjunction with a hydraulic control unit which includes circulation pumps, a two-

or three-way mixing valve and a valve actuator.



The ClimaticControl-HC has been designed for use in dry environments, e.g. in residential rooms, office spaces

and industrial facilities.



Verify that the installation complies with existing regulations before operation to ensure proper use of the instal-

lation.

3. Safety Instructions

Before starting work disconnect power supply!

All installation and wiring work on the ClimaticControl-HC must be carried out only when de-energized.

The appliance should be connected and commissioned by qualified personnel only. Make sure to ad-

here to valid safety regulations, in particular to VDE 0100 (German standard governing power installa-

tions of nominal voltages ≤ 1000 VAC).

The ClimaticControl-HC is neither splash, nor drip-proof. Therefore, they must be mounted at a dry place.

Do not interchange the connections of the sensors and the 230V connections under any circumstances! Inter-

changing these connections may result in life endangering electrical hazards or the destruction of the appliance and

the connected sensors and other appliances.

5. Installation and Electrical connections

5.1 ClimaticControl-HC Installation

The ClimaticControl-HC can be installed directly on a solid base (e.g. a wall). For this purpose the front panel of the

ClimaticControl-HC must be removed (fig. 4a) and the back section should be fastened using appropriate screws

and pins (these are not included in the scope of supply) (fig 4b) Fix the climatic control HC on a plane surface (wall…)

If the ClimaticControl-HC has been factory fitted with cables for connecting to a pump, valve drive, temperature

limiter, sensors etc., take care not to damage or crack the cables during the installation. Furthermore these cables

should not subjected to any tensile stress during installation. The cables will be fixed by means of the device for

strain relief at the ClimaticControl-HC.

If the ClimaticControl-HC is delivered together with a hydraulic control unit (for example FRG or FlowBox) and if it is

not attached to that unit by any installation plate or support, it should be installed next to that unit.

Pay attention to the correct connection of the cables if the ClimaticControl-HC is not installed directly on a hydraulic

control unit but at some other place for the reason of better access.

Refer to the directions about this in section 5.2 Electric connections.

5.4 Room Temperature – Direct Plug In

As an option you can plug in a room thermostat to the ClimaticControl-HC. Direct plug in of a room thermostat op-

timizes the operational time of the circulation pump and even the supply flow temperature depending on the condi-

tions in the main room.

5.4.1

Mixed circuit (Water Floor), standard room thermostat, wired type

If a wired type of a standard room thermostat is plugged in and the preset room temperature is reached in

the room, the under floor circulation pump switches off after pump delay time. (PUMP:  System parame-

ters: pump delay time)

5.4.2

Direct circuit (Panel Heater), standard room thermostat, wired type

If a second circulation pump is installed and managed by the ClimaticControl-HC (Inst:  System param-

eters: installation type, “2P.x”), you can install a second wired room thermostat to manage the working of

the high temperature pump.

This pump will work in the following way: If the preset room temerature is reached in the room the High

water temperature circulation pump switches off after pump delay time. (PUMP:  System parameters:

WFHT-RF BASIC WFHT-RF LCD MILUX-RF-xxx MILUX-RF-Hygrostat

Only RF thermostats from the WFHT-RF series or the MILUX-RF series can

be used with an active antenna 433,92.

The MILUX-RF Hygrostat can be used only with the 433,92Mhz frequency

RF thermostat initialization to the Controller:

 SYSTEM PARAMETERS MENU, section

RADIO-CONFIGURATION with RF room thermostat

fig.8

If a radio frequency room thermostat is plugged in, the flow temperature calculated on the basis of outdoor

temperature and the curve (= flow temperature preset value) is optimized depending on the main room tempera-

ture.

The offset value is calculated in the following way:

Adjustment = preset value of supplied temperature + (room temperature - actual value) х compen-

sation offset

(Compensation offset:  System parameters: “tr1o” Flow temperature offset for “trF1”)

Example 1: preset calculated value of flow temp. = 35 °C; room temperature: preset value = 21 °C,

actual value = 19 °C; offset (tr1o) = 1,5

Estimation 1: 35 °C + (21 °C – 19 °C) × 1,5K =>> flow temperature increased by 3,0K to 38 °C

Example 2: preset value of flow temperature = 35 °C; room temperature: preset value = 21 °C,

actual value = 22 °C; offset (tr1o) = 1,5

Estimation 2: 35 °C + (21 °C – 22 °C) × 1,5K =>> flow temperature decreased by 1,5K to 33,5 °C

The pump will be switched off when room temperature will be 1°C upper the setting temperature

of the thermostat.

If a Milux-RF-Hygrostat is used, the program feature (See Chapter Error! Reference source not found.) is deported on the

thermostat user interface.

5.4.4

Wireless room Hygrostat (Water Floor thermostat “trF1”)

If a radio frequency room Hygrostat is plugged in, the flow temperature calculated on the basis of outdoor

temperature and the curve (= flow temperature preset value) is optimized depending on the main room

temperature. (See the previous part for more explanation)

The working mode (Heating or Cooling) of the installation could be managed by the end user directly on

the room hygrostat. (See the MILUX humidity leaflet for more explanation)

The residual humidity will be supervised by the MILUX-RF hygrostat in the house. If humidity is detected

the “Wcal“ temperature will be increased by step of 0.1°C/minute to avoid a too cold water on the hydraulic

circuit and risk of condensation in the house.

5.4.5

Wireless RF room thermostat (High temperature circuit thermostat “trF2”)

If a second circulation pump is installed and managed by the ClimaticControl-HC (Inst:  System param-

eters: installation type, “2P.x”), you can install a second radio frequency room thermostat to supervise the

working of the high temperature pump.

This pump will work in the following way: If the preset room temerature is reached the High water

temperature circulation pump switches off after pump delay time. (PUMP:  System parameters: pump

delay time)

Note: Only a standard room thermostat could be installed on the second circuit.

Ex: WFHT-RF (BASIC, LCD or MILUX).

5.4.6

Wireless RF outside sensor (Inst:  System parameters: Input, “OUSE”).

As an option you can plug in a wireless RF outside sensor room thermostat to the ClimaticControl-HC. This solu-

tion is very interesting in rehabilitation, to avoid wires trough the wall, in a building management with several CC-

HC, in this case only one outside sensor can be installed to manage all the building.

WIRELESS OUTSIDE

SENSOR

The wireless outside sensor can be used only with the 433,92Mhz frequency

RF outside sensor initialization to the Controller:

fig.9

RF supervising function.

If the ClimaticControl-HC is installed with RF thermostat(s) and there is no radio signal received during more than 2

hours, a display alarm will be activated,the backlight and the small RF antenna logo radio will blink.

To stop the alarm, maintain the (OK) button pressed for about 10 seconds.

Check the batteries of the RF thermostat(s) or outside RF sensor. Please replace them if exhaust-

ed.

Check the position in which the antenna was installed. It must be installed in vertical position.

Installation in or on a metal body can abate the power of radio transmission. Minimize the distance

to the RF thermostat.

If radio alarm is displayed:

Due to the wireless thermostat, the regulation will continue to work as an installation without thermostat (no com-

pensation).

Due to the Wireless outside sensor, the regulation will continue to work with the last value received from the out-

side sensor.

5.4.7

Inputs functions (In1 & In2)

If no wired thermostat is installed in the house, you will have the possibility to use the two available inputs of your

ClimaticControl-HC for different functions (Inst:  System parameters: Input, “In1 & In2”).

Input1

Inst:  System parameters: Input, “HC”

You could use the input 1 to connect the an external signal which give the Heating or Coling working mode

of the installation (This signal could be done directly by a reversible input).

Inst:  System parameters: Input, “Aqu”

1/ You could use the input 1 to connect the an imersion thermostat witch schould be placed in a storage

tank. In Heating mode this immersion thermostat will be use to switch off the circulation pump (Pump1) to

avoid cold water circulation in the circuit if the storage tank is discharged. (This solution is generally use

when solid wood burner is installed)

2/ You could also use this input to have a priority on domestic hot water.

In this case the pump of the heating circuit will be stopped to keep the priority on the domestic hot water. This

configuration is not compatible with the Efficiency Point PE=Yes as the output is used to control the heating stage

2 (See parameter #15 in Chap 7.1 System parameters setting)

Note:

The heating output will stay activated even if the aquastat have stopped the circulation pump.

To avoid problem in cooling mode, if the storage tank is filled with cold water (by heat pump...) the

aquastat function will be automatically desactivated.

Radio

alarm:

Inst:  System parameters: Input, “C_b”

In case of mutizone regulation “WFHC Master RF with or without Heat&Cool function” is installed you

could use the input 1 to connect the pump relay output to swtich off the circulation pump1 in case of no

water circulation demand is asked in the house.

Note:

The heating output will follow the circulation demand from the pump1.

Input2

Inst:  System parameters: Input, “HC”

You could use the input 2 to connect the an external signal which give the Heating or Coling working mode

of the installation (This signal could be done directly by a reversible input).

“HC” is only available if Input1 is set on “no or Aqua”

Inst:  System parameters: Input, “Aqu”

You could use the input 2 to connect the an immersion thermostat witch schould be placed in a storage

tank. In Heating mode this immersion thermostat will be use to switch off the circulation pump to avoid cold

water circulation in the circuit if the storage tank is discharged.

The immersion thermostat connected on the Input2 will manage the working of the main circula-

tion pump (Mixed circuit) if the ClimaticControl-HC drive only one pump.

In the installation with two circulations pumps, the immersion thermostat connected on the Input2

will manage the working of the 2nd circulation pump (direct circuit).

Note:

The heating output will stay activated even if the aquastat have stopped the circulation pump.

To avoid problem in cooling mode, if the storage tank is filled with cold water (by heat pump...) the

aquastat function will be automatically desactivated.

Inst:  System parameters: Input, “C_b”

In case of mutizone regulation “WFHC Master RF with Heat&Cool function” is installed you could use the

input 2 to connect the pump relay output to swtich off the circulation pump in case of no circulation demand

is asked in the house.

The WFHC connecting box connected on the Input2 will manage the working of the main circula-

tion pump (Mixed circuit) if the ClimaticControl-HC drive only one pump.

In the installation with two circulations pumps, the WFHC connecting box connected on the Input2

will manage the working of the 2nd circulation pump (direct circuit).

6. Types of operating modes / Program menu

6.1 Heating and cooling switch

There are several ways to switch the system between heating and cooling.

 Use parameter #0 Type (See Chap 7.1)

 Use the user interface of the Climatic Control HC if parameter #0 Type=Rev (See Chap 7.1)

 Use the user interface of the paired MILUX-RF HYGROSTAT if parameter #0 Type=Rev

 Use Input 1 parameter #11 In1=HC or Input 2 parameter #12 In2 =HC (See Chap 5.4.7 and Chap 7.1)

6.2 Types of operating modes

Selection of the operating mode is done using the arrow keys (◄) and (►). The cursor must be positioned on the

symbol of the relevant operating mode.

COMFORT mode of operation

Unlimited operation in COMFORT mode .

The system runs in constant comfort mode. The ClimaticControl-HC adjusts the flow temperature depend-

ing on the outdoor temperature and the selected curve. No temperature setback.

The display Pos. 5 shows the current flow temperature and the outside temperature at 13 (damped val-

ue). By pressing the button (OK) the preset value of flow temperature appears for about 3 seconds at 5.

At the same time the manually selectable deviation is displayed at 13 (factory setup: 00.0 = no deviation).

Using the buttons (+) or (-) you can adjust the preset value of the flow temperature. If changed, the sym-

bol

appears on the display.

In heating mode of operation if no room thermostat is installed ( MuB:  5.3), the circulation pump is

running continuously. The pump switches off if the mixing 3 way valve is closed for the setting time

(PUMP:  System parameters: pump delay time). That is the case when the room heating is sufficient

and the room thermostat closes all heating circuits by means of actuators. The same happens when the

value of flow temperature calculated by the ClimaticControl-HC becomes lower than the actual tempera-

ture value because of rising outdoor temperatures. If the actual value of the flow temperature falls below

the preset value, the pump will restart.

In this case to ensure a correct measure of the water temperature the pump will be start each 30min

for a short time to measure the real temperature of water inside the hydraulic circuit.

To ensure energy saving operating mode of the pump it could be switched by a “pump logic” of a elec-

tric connecting box. The connecting box is normally used together with room thermostats and electro-

thermic actuators. The “pump logic” is a potential free switching relay, the contact of which is closed

whenever higher temperature is demanded in any of the rooms. If all rooms are warm enough, the contact

opens and the pump turns off. ( MuB:  5.5)

If the heat generator / boiler (WE) is in temperature setback and the temperature supplied by the WE

is below the preset temperature calculated by the ClimaticControl-HC, heating mode is not available.

However if the circulation pump is actually running and the 2/3-way valve may also be opened by the 3-

point actuator because of room heating demand, the preset value of flow temperature may be exceeded

for a short period of time when the WE switches to heating mode. In this case, if a temperature limiter is

available, the pump might switch off and then pump operation will be possible only after the temperature

drops below the preset maximum temperature of the TB.

Trouble-shooting: The TB should be installed at a greater distance from the control unit. If necessary you

can set the TB to a higher temperature until the pump starts. After a few minutes of pump operation the

maximum allowable temperature set on the TB should be restored. Alternatively you can remove the TB

from the pipe for a while and leave the pump running for a few minutes. Then refit the TB again to the

pipe.

AUTOMATIC mode of operation

Automatic mode of operation using the built-in or user programs.

The ClimaticControl-HC is controlled according to the selected built-in or user program ( 6.2.).

The flow temperature is controlled depending on the outdoor temperature and the curve with room com-

pensation if RF thermostat is installed. ( 5.3.3 – 5.3.5).

 The room compensation function will be different depending of the RF thermostat installed:

* With WFHTRF-BASIC or LCD (Non programmable thermostat)

The room temperature compensation will be taken in account only during Comfort period of the pro-

gram. During the Reduced period the Water temperature will follow the curve minus the temperature

setback offset.

With

MILUX RF (Programmable

thermostat)

The room temperature compensation will be taken in account during Comfort and Reduced period

of the program. In this case the program of the MILUX RF should be the same of the water program ad-

justed on the CC-HC to have the best optimising energy consumption (the water temperature will be re-

duced due to the CC-HC program (in ) and by the setting temperature reduced also in the room due to

the MILUX RF program.

With MILUX-RF HYGROSTAT (Programmable Heat and Cool thermostat with Humidity supervising)

The program will be now done on the MILUX-RF HYGROSTAT (Program made on Zone1 see the user

guide of the MILUX-RF HYGROSTAT for more explanation).

The room temperature compensation will be taken in account during Comfort and Reduced period

of the MILUX-RF HYGROSTAT program.

The Comfort and Reduced manual offsets added or subtracted to the calculated water temperature will be

always adjusted on the both working mode of the CC-HC ( 0.00°C & -10.0°C by default).

 For the operation of the circulation pump please refer to the section of COMFORT mode of operation.

REDUCED TEMPERATURE mode of operation

Unlimited operation in REDUCED TEMPERATURE mode .

This is a constant mode of operation of the system. The ClimaticControl-HC adjusts the flow temperature

continuously on the basis of outdoor temperature and the selected curve and substracting the value of

temperature setback (factory setting -10.0 К in Heating mode & +3.0 К in Cooling mode).

The display indicates the current flow temperature at 5 and the outside temperature at 13. By pressing the

button (OK) the preset value for the supply flow temperature reduced by the setback in temperature is

displayed at 5 for 3 seconds. Simultaneously the reducing difference appears in 13 (without deviation =

-10.0). It can be changed by the buttons (+) or (-).

 For the operation of the circulation pump please refer to the section of COMFORT mode of operation.

 See the previous part for more explanation concerning the room compensation function when RF

thermostat is installed.

ABSENCE/VACATION mode of operation

Time-limited operation of REDUCED TEMPERTURE mode .

Duration can be set between 1 and 24 hours and up to a maximum of 44 days. When this period is ex-

pired the ClimaticControl-HC switches back to operating mode .

By means of the arrow keys (◄) the cursor is first moved to . Then appears on the display at 13.

The duration of absence can be changed using buttons (+) or (-).

Example:

= 1 hour; = 1 day

Both symbols and start blinking. The remaining time is displayed at 13.

To discontinue this mode of operation before time you have to set the remaining time at 13 to using

the

(

)

key.

STOP mode

This mode is used to switch off the system.

The device switches off the system. The ClimaticControl-HC software version is indicated on the display

for about 3 seconds and then switches off (no indications).

By pressing any of the keys the ClimaticControl-HC can be switched on.

REMARK: When the ClimaticControl-HC is in STOP mode,

In Heating mode only an Anti-freeze function can restart heat relay and circulation pump to maintain the

water temperature above 10°C.

Heat & Cool Mode

Use this mode to change the working mode of your installation, Heating or cooling mode.

This mode will be only displayed if:

The CC-HC is configured to manage a reversible installation (Inst:  Parameters menu: Type, “Rev”)

No MILUX-RF HYGROSTAT is installed ( 5.3.4) and configured to manage the Heat and Cool mode.

No CC-HC inputs (In1 or In2) have chosen for a H_C signal input. ( 5.5)

Carfull:

IF Heat pump or other system is used and not linked with the ClimaticControl-HC, pay attention to change

the working mode on it before change on the ClimaticControl-HC. Because in this case the regulation will

not work in the correct way.

TIME AND DATE – setting

In this menu you can set the actual time and date as well as the day of the week.

Using the cursor select first and then press the (OK) key.

By keys (+) or (-) set the minutes; confirm by pressing (OK).

By keys (+) or (-) set the hour; confirm by pressing (OK)

By keys (+) or (-) set the day of the week; press (OK) to confirm.

PROGRAM menu

In this menu you choose the program of the Controller (duration of the periods for operation in reduced temperature and

heating mode), which is to be followed in operating mode . You can choose between factory set

programs from P1 to P9 ( 6.2.1.) and one of the user’s programs from U1 to U4.

First you select with the help of the cursor. The indication appears at 5. Press the (OK) key and the

indication

starts blinking. By the keys (+) or (-) now you can select the program you need and confirm it by pressing (OK).

User-defined Programs (U1 – U4)

If you choose one of the user programs from U1 to U4, you can program the REDUCED temperature and NORMAL

heating times directly. Proceed as follows:

The key (+) allow you to choose a COMFORT period at the blinking cursor time. The key (+)

allow you to choose a REDUCED period at the blinking cursor time.

At 13 the time indication blinks and day 1 is highlighted, while at 7 the time cursor blinks at 0 h on the sym- bol (heating

mode). Pressing the (-) key you can move the time cursor to the symbol (REDUCED tem- perature

mode). Then the time cursor jumps to the next hour. Thus COMFORT and REDUCED tempera- ture cycles are selected

using the (+) and (-) keys.

the programmed values for day 1 are stored. Programming other days is done using identical procedure

moving the cursor by pressing (►). When you switch over to programming the next day the program for the

previous day is saved. On completing the programming of the last day 7, the indication first switches to the

program menu , and in about 15 seconds back to .

If during programming no inputs are made within 20 seconds, indication switches first to the program menu

, and in another 15 seconds it returns to . The inputs were not stored.
