Preheating
Preheating is the process of switching on the heating early, i.e. before the start of the
day period. This ensures that the room temperature has already reached the setpoint
temperature at the start of the day period. The required pre-heating time is
determined by the Function. The preheating time increases with increasing difference
between the setpoint room temperature during day mode and the actual room
temperature. A longer preheating time is also required if it is colder outside. A
minimum and a maximum preheating time can be set.
