Heating curve
4.8.1 Heating curve (heating characteristic curve)
The heating curve describes the flow temperature of a heating system as a function
of the outside temperature.
The heating curve is preset by the installer *.
Carry out temporary changes to the room temperature settings via the “Daytime
room temperature” or “Reduction temperature.”
The heating characteristic curve settings should only be changed if the room tem-
perature is not reached over a longer period of time during the heating period.
Recommended settings:
Underfloor heating:
0.3 to 0.8
Radiator heating:
1.0 to 2.0
Convector heating:
1.4 to 2.0

Example:
You have set the system to radiator heating and a heating curve slope of 1.0. At an
outside temperature of -10ºC, this results in a flow temperature of approx. 52ºC if a
temperature of 20ºC is required.

* Info :
The heating curve for the direct circuit is set to OFF by default. The direct heating circuit
is activated automatically by setting a value.
