Heating curve
3.8.1 Heating curve (heating characteristic curve) information
The heating curve describes the flow temperature of a heating system as a
function of the outdoor temperature.
The heating curve is preset by the installer *.
Conduct temporary changes to the room temperature settings via the "Day-
time room temperature" or "Reduced temperature".
The heating characteristic curve settings should only be changed if the
room temperature is not reached over a longer period of time during the
heating period.
Recommended settings:
Floor heating:
0,3 to 0,8
Radiator heating:
0,8 to 2,0

Example:
You have set the system to radiator heating and a slope of the heating char-
ac ter istic curve of 0,6. At an outdoor temperature of -10°C this results in a
flow temperature of approx. 38ºC, if a temperature of 20°C 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.
