You can use this function to read which heat demand the
system control reports to the heat generator, the heat
pump or the additional module for the heat pump.
Standby
: The system control does not report any heat de-
mand.
Heat. mode
: The system control reports a heat demand for
the heating mode.
Cooling
: The system control reports a heat demand for the
cooling mode.
DHW
: The system control reports a heat demand for do-
mestic hot water generation.

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.

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 heating installation 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-compensated. Depending on the basic system dia-
gram, the heating circuit may be a mixing 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
required functions appear in the display.
