3.3 Nominal room temperature setpoint
•
Straightforward setting of the required nominal room temperature setpoint
The heating system uses 3 different setpoints that can be adjusted:
•
The nominal room temperature setpoint described here
•
The reduced room temperature setpoint (setting on operating line 27)
•
The frost protection setpoint of the room temperature (setting on operating line 28)
The nominal room temperature setpoint is pre-adjusted with the setpoint knob. It is lo-
cated on the controller front for direct access by the user.
