The heating system has 3 different setpoints that can be adjusted:
The reduced room temperature setpoint described here.
The nominal room temperature setpoint (to be adjusted with the setpoint knob).
The frost protection setpoint of the room temperature (setting on line 28).
Setting range
TRF...TRN
TRF Room temperature for frost protection (setting on line 28)

If the required temperature level cannot be set, the adjustment made with the setpoint
knob may be too low. It is not possible to set a value above the adjustment made with
the setpoint knob.
