The prescribed heating curve for your house can be viewed in
the menu "heating curve". The task of the heating curve is to
give an even indoor temperature, regardless of the outdoor
temperature, and thereby energy effi cient operation. From this
heating curve, the control module determines the temperature
of the water to the heating system, supply temperature, and
therefore the indoor temperature. Select the heating curve and
read off how the supply temperature changes at different
outdoor temperatures here. If there is cooling function, the
same settings can be made for the cooling curve.
Curve coefficient
The heating/cooling curve shows the relation between the
target supply temperature and the corresponding outdoor
temperature. A steep curve indicates that supply temperature
becomes higher at low outdoor air temperature in heating and
it becomes lower at high outdoor air temperature in cooling.

Steeper curve slope
The optimum slope depends on the climate conditions in your
location, the type of heating device (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
In the event of making fine adjustments of the indoor
temperature, the curve must be offset up or down instead,
this is done in menu 1.1 "temperature".
Curve offset
The target temperature can be off set in parallel over the entire
outdoor temperature range by this function. This is offset by
5 °C by adjusting 2 steps.
The target temperature can be parallel offset in the entire
outdoor temperature range with this function. It is offset by
