Rooms with a room unit (
/Auto button) or presence detector
The operating mode in Rooms 1 and 2 of a building is determined centrally by the Use
and Occupancy time schedules. The Occupancy time schedule defines the period
during which both rooms are required to be available (Standby).
Comfort mode is then initiated locally via the room unit (Room 1) or presence detector
(Room 2).
The following conditions are specified:
• Overall, the building is in use from 06.00 to 22.00 (Building use time schedule).
• Rooms 1 and 2 must be available from 08.00 to 18.00 (Occupancy time 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 re-activated with the Auto switch on the room unit (2).
Comfort remains active for the pre-defined Temporary Comfort mode period (see
page 143). However, at the end of the "building-in-use" period the Temporary
Comfort period is also overridden and the room operating mode reverts to Economy
mode (3).
• In Room 2, in the evening, there are still people in the room 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 mode. An alarm can also be tripped, if required.
