The behaviour can be adjusted separately for each heating circuit.
→ Room temp. mod.:
The installed temperature sensor measures the current room temperature. The system control calculates a new target room temper-
ature that is used to adjust the flow temperature.
–
Difference = Set target room temperature - current room temperature
–
New target room temperature = Set target room temperature + difference
Prerequisite: In the Zone assignment: function, the system control and/or the remote control is assigned to the zone in which the
system control or remote control is installed.
The Room temp. mod.: function is ineffective if No assignmt is activated in the Zone assignment: function.

→ Increase in
The heating circuit is used to increase the return flow. The increase in
return return prevents an excessive temperature difference between the heat-
ing flow and return, and protects against corrosion in the floor-standing
boiler when the dew point is not reached for an extended period.
Select a temperature at which the heating water should flow back into the floor-standing
boiler.
Enter the upper limit for the outdoor temperature. If the outdoor temperature rises above the
set value, the system control deactivates heating mode.
Select the temperature for the fixed value circuit which applies within the time period.
Select the temperature for the fixed value circuit which applies outside of the time period.
The heat curve (→ section "Product description") is the dependence of the flow temperature
on the outdoor temperature for the desired temperature (target room temperature).
Enter the lower limit for the target flow temperature. The system control compares the set
value with the calculated target flow temperature, and regulates to the larger of these values.
Enter the upper limit for the target flow temperature. The system control compares the set
value with the calculated target flow temperature, and regulates to the smaller of these val-
ues.
→ Eco
The heating function is switched off and the frost protection function is
activated.
At outdoor temperatures that are below 4 °C for longer than four hours,
the system control switches the heat generator on and regulates to the
Set-back temperature: °C. At an outdoor temperature above 4 °C, the
system control switches the heat generator off. The monitoring of the
outdoor temperature remains active.
Heating circuit behaviour outside of the time periods. Prerequisite:
– Time-contr. is activated in the Heating → Mode: function.
–
Active or Inactive is activated in the Room temp. mod.: function.
If Expanded is activated in the Room temp. mod.:, the system control
regulates to the target room temperature 5 °C independently of the out-
door temperature.
→ Normal
The heating function is switched on. The system control regulates to the
Set-back temperature: °C.
→ Inactive
→ Active
Adjusting the flow temperature based on the current room temperature.
→ Expanded
Adjusting the flow temperature based on the current room temperature.
The system control also activates/deactivates the zone.
–
The zone is deactivated: Current room temperature + 2/16 K > set
room temperature
–
Zone is activated: Current room temperature < set room temperature
- 3/16 K
Prerequisite: A heat pump is connected.
The system control compares the set minimum cooling target flow temperature with the cur-
rent dew point + set dew point offset. The system control selects the higher temperature for
the target flow temperature in order to prevent condensate.
Prerequisite: The Cooling possible: function has been activated.
