Curve coefficient
The slopes of the heating /cooling
curves indicate how many degrees
the supply temperature is to be in-
creased/reduced when the outdoor
temperature drops/increases. A
steeper slope means a higher supply
temperature for heating or a lower
supply temperature for cooling at a
certain outdoor temperature.

Steeper curve slope
Supply temperature
Outdoor temperature
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 curve is set when the heating installation is installed, but may need adjusting
later. Normally, the curve will not need further adjustment.
Caution
When making fine adjustments of the indoor temperature, the curve
must be offset up or down instead, this is done in menu 1.1 temper-
ature .
Curve offset
An offset of the curve means that the
supply temperature changes as much
for all the outdoor temperatures, e.g.
that a curve offset of +2 steps in-
creases the supply temperature by
5 C at all outdoor temperatures.
