5.3 Determine the room operating mode
in DESIGO (S-mode)
In S-mode, the effective room operating mode of the room controller depends on the
central Use and Occupancy time schedules and/or on local influences such as window
contacts, presence detectors or a room unit.
The diagram below shows the priority of these influences and how they are processed
by the room controller:
Central Local
Window contact
Building use
S
Occupancy

Presence detector
Room unit
Temporary Comfort mode
• The effects of Priority 1 and Priority 2 are similar in nature to continuous states
• The Priority 3 influences are treated as events .
The key factor is the moment at which the state changes (trigger edge).
If the mode is later changed by another source of priority 3, the last change
applies .
