Max. target flow temperature:°C

Enter the upper limit for the target flow temperature. The system
control compares the set value with the calculated target flow tem-
perature, and regulates to the smaller of these values.
Factory setting:

–

90 °C for a conventional heat generator

–

55 °C for a heat pump and/or mixed circuit

Set-back mode:

The behaviour can be adjusted separately for each heating circuit.
Factory setting:

Eco

The heating function is switched off and the frost protection func-
tion is activated.
At outdoor temperatures that are below 4 °C for longer than four
hours, the system control switches the heat generator on and reg-
ulates to the

Set-back temperature: °C

. At an outdoor temperat-

ure 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.

Mode:

Room temp. mod.:

The installed temperature sensor measures the current room tem-
perature. 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 tem-
perature

–

New target room temperature = Set target room tempe
difference

Prerequisite: In the

Active

Adjusting the flow temperature based on the current room temper-
ature.

Expanded

Adjusting the flow temperature based on the current room temper-
ature. The system control also activates/deactivates the zone.

–

The zone is deactivated: Current room tempe 2/16 K >
set room temperature

–

Zone is activated: Current room temperature < set room tem-
perature - 3/16 K

Cooling possible:

Prerequisite: A heat pump is connected.
Factory setting;

Dew point monitoring:

The system control compares the set minimum cooling target flow
temperature with the current 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.

Factory setting:

Yes

Min. cooling targ. flow temp.: °C
