Heating curve/cooling curve
Heating and cooling curves represent the relationship
between the outside temperature, set room tempera-
ture and heating circuit flow temperature.
In order to guarantee sufficient heat at any outside
temperature, the conditions of your building and your
heating system must be taken into consideration. For
this, you can adjust the slope and level of the heating
curve separately for each heating circuit.
You can also adjust the cooling curve for cooling
mode.

The lower the outside temperature, the higher the flow
temperature in the heating circuit.

Example: setting the heating curve slope and level
The heating curves shown apply with the following set-
tings:
■
Heating curve level = 0
■
Standard room temperature (set room temperature)
= 20 °C
