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:

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.
