Examples of Heating Curves
You can see in the diagram below how the heating
curve changes with different Inclination settings. The
gradient of the curve shows the temperatures that the
radiators require at different outdoor temperatures.
Curve Inclination
The inclination value which is set is the primary flow
temperature when the outside temperature is –15 °C.

Adjustment
The curve can be parallel displaced (adjusted) by
the desired number of degrees to adapt to different
systems/houses.
An example
Inclination 60 °C
Adjustment 0 °C
In this example, the maximum outgoing primary flow
temperature is set at 55 °C.
The minimum permitted primary flow temperature is
27 °C (e.g. summer-time basement heating or the floor
circuits in a bathroom).
Inclination 50 °C
