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 the 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 heating curve
slope and parallel displacement is not required. It can only be switched on or off.
To assure 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 room sensor) (if such valves are present, they must be set to their fully
open position).

732 1032 1332 24-hour heating limit
The summer / winter heating limit is used to switch the heating on and off in the course
of the year, depending on temperature conditions. In Automatic mode, switching on / off
takes place automatically, so there is no need for the user to do this manually. By
changing the setting, the respective periods of time will be shortened or extended.
