Heating Curve Slope Adaptation

The heating curve slope adaptation has the following settings (HCA-04):

If any type of adaptation is set, no direct room temperature compensation of the mixed water temperature setpoint is possible.

The heating curve slope adaptation is enabled if all following conditions are true for 6 hours:

If the parameter HCA-04 set to 2 = "new start", the heating curve slope adaptation will be restarted. This new start has to be selected before the first download of the controller or when the building load has been changed after a renovation. After 24 hours of operation the heating curve slope adaptation will automatically be reset to the 1 = "adaptive".


IMPORTANT!

To ensure a satisfactory adaptive operation or direct room temperature compensation, the room temperature sensor should be placed in a representative room, in which no thermostatic radiator valves are mounted.
