Comfort mode
Comfort mode is the controller's reference mode. The values in the night and standby operating
modes are based on this. The Comfort operation mode should be activated when the room is used.
The basic comfort value is parameterised as the setpoint.
If the controller mode is set to Heating & cooling, the basic comfort value applies for the heating
process. In cooling mode, the value of the dead zone between heating and cooling is added.

Night mode
The night operating mode should cause a significant temperature reduction/increase, e.g. at night or
on weekends. The value can be freely parameterised and refers to the basic comfort value. So if a 5K
reduction has been parameterised and a basic comfort value of 21°C has been set, the setpoint for
night operation mode is 16°C. In cooling mode, there is a respective increase in the value.
