In the menu heating curve the so-called heating curve for your house
can be viewed. The task of the heating curve is to give an even indoor
temperature, regardless of the outdoor temperature, and thereby energy
efficient operation. It is from this heating curve that the indoor module’s
control computer determines the temperature of the water to the heating
system, flow line temperature, and therefore the indoor temperature. You
can select heating curve and read off how the flow line temperature
changes at different outdoor temperatures here.
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 temperat-
ure drops/increases. A steeper slope
means a higher supply temperature
at a certain 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 heating curve is set when the heating installation is installed, but may
need adjusting later. Thereafter the heating curve should not need further
adjustment.
