Rooms with a room unit ( /Auto button) or presence detector
The room operating mode in rooms 1 and 2 of a building is determined centrally by the
Use and Occupancy schedules . The RoomOccupancy schedule defines the period
during which both rooms must be available (standby).
Comfort room operating mode is then initiated locally via the room unit (room 1) or
presence detector (room 2).
The following conditions are specified:
•
The building is in use from 06.00 to 22.00 ( Use schedule).
•
Rooms 1 and 2 must be available from 08.00 to 18.00 (room occupancy schedule:
standby ).
•
The occupants of Room 1 continue working in the evening beyond the programmed
occupancy period. At the end of the programmed period of occupancy, the room
operating mode changes to
Economy even if the room unit is set to Auto (1). Comfort
mode can now be reactivated with the Auto switch on the room unit (2). Comfort
remains active for the set Temporary Comfort mode period (see page 103). At the
end of the building-in-use period, however, the Temporary Comfort mode period is
overridden and the room controller returns to
Economy mode (3).
•
Room 2 is occupied in the evening beyond the building-in-use period (4). However,
at the end of the building-in-use period, the room operating mode still changes to
Economy. An alarm can be triggered if required.
