Note
If the WPE heat pump extension is connected, you can
specify separate values for heating circuit 4 and heating
circuit 5.
 COMFORT TEMPERATURE
Select COMFORT TEMPERATURE to set the set room temperature
for comfort mode. When the heat pump is in comfort mode (see
PROGRAMS/ HEATING PROGRAM or operating mode COMFORT
MODE), the heat pump heats the heating water to the value set
here.
 ECO TEMPERATURE
Select ECO TEMPERATURE to set the set room temperature for ECO
mode. When the heat pump is in ECO mode (see PROGRAMS/
HEATING PROGRAM or operating mode ECO MODE), the heat pump
heats the heating water to the value set here.
 MINIMUM TEMPERATURE
The set MINIMUM TEMPERATURE is safeguarded by the controller
of the relevant heating circuit.
The minimum temperature ensures, with underfloor heating for
example, that the screed/substrate is never too cold.
 MAXIMUM TEMPERATURE
The set MAXIMUM TEMPERATURE limits the permissible flow tem-
perature in heating circuit 2.
The limit has priority over a higher set flow temperature calculated
by the heat pump manager.
 MIXER DYNAMICS
Using this value, the control characteristics or the effect of mixer
runtime on the controller can be adjusted.

300 50
 ROOM INFLUENCE
Only in conjunction with a remote control.
In this menu item you set the degree of influence that the outside
temperature or current room temperature has on the control unit.
With weather-compensated control, the room is heated in relation
to the outside temperature and the set heating curve.
With room temperature-dependent control, the room is heated
consistently to the temperature set on the remote control.

Heating circuit pump control with remote control
 Set the ROOM INFLUENCE to a value greater than 0.
If the actual room temperature is higher than the set room tem-
perature plus 1K, the heating circuit pump is switched off.
If the actual room temperature is lower than the set room tem-
perature, the heating circuit pump is switched on.
 HEATING CURVE RISE
Menu item HEATING CURVE RISE enables you to set one heating
curve each for heating circuits1, 2 and 3. If a heat pump extension
is connected, this also applies to heating circuits 4 and 5.

ARD SETTING under the parameter FIXED VALUE OPERATION
menu, heating curve 1 is not displayed. The display will show
SET FIXED TEMPERATURE with the relevant temperature.
