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
