If the room occupancy times of the various geographical zones are identical, a time
switch can be defined as the master. The other controllers assume the master
occupancy times as time switch slaves.

See section 6 for a detailed description of time switch operation.
If two ventilation plant
s or one heating circuit and one ventilation plant supply the
same rooms, they also have the same geographical zone.
The two plants acquire the same room temperature and use the same room
occupancy schedule (i.e. the room operating mode is the same).
If the room operating mode is changed with the mode button on the room unit (e.g.
QAW740), the room control master assumes the change and sends it to the room
control slave.
In room control combinations heating circuit/ventilation plant, the ventilation plant
always assumes the room control master function.
