8.6 Heat generator 1, heat pump 1, additional
module
8.6.1 Reading the status
Menu → Installer level → System configuration [Heat gen-
erator 1 ----] → Status
Menu → Installer level → System configuration [Heat
pump 1 ----] → Status
Menu → Installer level → System configuration [Addi-
tional module ----] → Status
– You can use this function to read which requirement the
controller reports to the heat generator, the heat pump or
the additional module for the heat pump.
Standby: The controller does not report any energy require-
ment.
Heat. mode: The controller reports an energy demand for
heating mode.
Cooling: The controller reports an energy demand for cool-
ing mode.
DHW: The controller reports an energy demand for hot water
generation.
8.6.2 Reading the current flow temperature
Menu → Installer level → System configuration [ Heat
generator 1 ----] → Current flow temp.
Menu → Installer level → System configuration [ Heat
generator 1 ----] → Current flow temp.
Menu → Installer level → System configuration [ Addi-
tional module ----] → Current flow temp.
– You can use this function to read the current actual flow
temperature of the heat generator, the heat pump or the
heat pump's additional module.
8.7 HEATING 1
You can use the heating circuit for various functions (heating
circuit, pool circuit, fixed value circuit, etc.). The display only
shows the functions that you require when using the heating
circuit. You can use the overview to see which functions you
can set or read for your configuration.
Functions for the heating circuit (→ Page 35)
8.7.1 Setting Type of circuit
Menu → Installer level → System configuration → [HEAT-
ING1 ----] → Type of circuit
– You can use this function to define the functions that the
heating circuit is to have.
The first heating circuit in the system has the default setting
Heating. All other heating circuits have the default setting
Inactive, which you may have to activate.
Inactive: The heating circuit is not being used.
Heating: The heating circuit is being used to heat and is
weather-controlled. Depending on the system diagram, the
heating circuit may be a mixer circuit or a direct circuit.
Pool: The heating circuit is being used as a pool circuit.
You can connect the external pool controller to the DEM1
to DEMx input on the VR 70 or VR 71. If the terminals at the
input have short-circuited, there is no heat demand. If the
terminals at the input are open, there is a heat demand.
Fixed val.: The heating circuit is maintained at two fixed
target flow temperatures. The heating circuit can be switched
between two target flow temperatures.
Ret.fl.incr.: The heating circuit is used for the increase in
return flow. The increase in return flow is used to protect
against corrosion in the floor-standing boiler as a result of
falling below the dew point for an extended period.
DHW: The heating circuit is being used as a hot water circuit
for an additional cylinder.
Depending on the Type of circuit that is selected, only the
corresponding functions appear on the display as list entries.
8.7.2 Reading the status of the heating circuit
Menu → Installer level → System configuration → [HEAT-
ING1 ----] → Status
– You can use this function to read the operating mode for
HEATING1.
off: The heating circuit does not report any energy require-
ment.
Heat. mode: The heating circuit is in heating mode.
Cooling: The heating circuit is in cooling mode.
DHW: The heating circuit is in heating mode for the hot water
in the cylinder.
8.7.3 Reading the heating circuit's target flow
temperature
Menu → Installer level → System configuration → [HEAT-
ING1 ----] → Target flow temp.
– You can use this function to read the target flow temper-
ature for the heating circuit.
8.7.4 Reading the target flow temperature of the
pool circuit
Menu → Installer level → System configuration → [HEAT-
ING1 ----] → Target flow temp. pool
– You can use this function to read the target flow temper-
ature of the pool circuit.
8.7.5 Setting the day target flow temperature for
the pool circuit or fixed value circuit
Menu → Installer level → System configuration → [HEAT-
ING1 ----] → Target flow temp.: Day
– You can use this function to set the target flow temper-
ature for the pool circuit or fixed value circuit for the day
(within a time period).
8.7.6 Setting the set-back target flow temperature
for the pool circuit or fixed value circuit
Menu → Installer level → System configuration → [HEAT-
ING1 ----] → T.fl.temp.: Set-back
– You can use this function to set the target flow temperat-
ure for the pool circuit or fixed value circuit for the night
(outside of the time period).
