Value Meaning
0 Without priority:
Simultaneous room heating and DHW heating
possible
1 With priority:
■
No room heating during DHW heating
■
Heating circuit pump for heating/cooling cir-
cuit 2 is switched off for the duration of
DHW heating.
Note
Setting only useful in conjunction with an ex-
ternal buffer cylinder
934.5 Temperature differential, flow temperature, heating/cooling circuit 2
The required heating water temperature for heating/
cooling circuit 2 with mixer corresponds to the set flow
temperature for this heating/cooling circuit, plus the
correction value (offset) set here.
This enables the mixer to regulate more effectively and
prevents it from being permanently open.
934.6 Room temperature influence, heating, heating/cooling circuit 2
Only for heating operation via heating/cooling circuit 2
in conjunction with a room temperature sensor
Value Meaning
4 Weather-compensated control without room
temperature influence
7 Weather-compensated control with room tem-
perature influence: See also parameter 934.7.
934.7 Room temperature influence, heating/cooling circuit 2
With room temperature influence, the set flow temper-
ature determined from the heating curve is adjusted
according to the room temperature.
The higher the room temperature influence is set, the
greater the adjustment of the set flow temperature will
be.
Necessary conditions for room temperature influence:
■
Room temperature sensor is connected.
■
Weather-compensated mode is set.
■
Parameter 934.6 set to 7.
935 Properties, heating/cooling circuit 3
935.3 Priority DHW heating, heating/cooling circuit 3
Room heating can be temporarily interrupted to make
the heat-up time for DHW heating shorter. For this pur-
pose, the heating circuit pump for heating/cooling cir-
cuit 3 is switched off.
