The heating curve is used to generate the flow temperature setpoint, which is used to
maintain a certain flow temperature level depending on the prevailing weather
conditions. The heating curve can be adjusted with a number of settings, thus matching
heat output and room temperature to individual needs.
When the heating curve slope is raised, the rate of flow temperature increase is the
quicker the lower the outside temperature or, in other words, if the room temperature is
not correct at low outside temperatures but at higher outside temperatures, the heating
curve slope requires readjustment.

Parallel displacement of the heating curve is used to change the flow temperature
evenly across the entire outside temperature range or, in other words, if the room
temperature is always too high or too low, a readjustment must be made with the help
of parallel displacement.
Adaptation of the heating curve is used by the controller to automatically adapt the
heating curve to the prevailing conditions. In that case, a readjustment of the heating
curve slope and parallel displacement is not required. It can only be switched on or off.
To provide this function, following must be observed:
•
A room sensor must be connected
The " Room influence " setting must be selected between 1 and 99.
•
•
There should be no thermostatic radiator valves in the reference room (mounting
location of the room sensor) (If such valves are installed, they must be set to their
fully open position)
