The optimum slope depends on the climate conditions in your location, if the
house has radiators or under floor heating and how well insulated the house
is.
The heating curve is set when the heating installation is installed, but may
need adjusting later. Thereafter the heating curve should not need further
adjustment.
Caution
In the event of making fine adjustments for the indoor temperature, the heat
curve must be offset up or down instead, this is done in menu 1.1

Curve coefficient
The slope of the heating curve indic-
ates how many degrees the supply
temperature is to be increased/re-
duced when the outdoor temperature
drops/increases. A steeper slope
means a higher supply temperature
at a certain outdoor temperature.
Curve offset
An offset of the heating curve means
that the supply temperature changes
as much for all the outdoor temperat-
ures, e.g. that a curve offset of +2
steps increases the supply temperat-
ure by 5 °C at all outdoor temperat-
ures.
