5.4 Determine the room operating mode with
third-party products (S-mode)
In S-mode the effective room operating mode of the room controller depends on the
central Room operating mode time schedule and/or on local influences such as window
contacts, presence detectors or room units.
The diagram below shows how these influences are processed by the room controller,
and their priority:

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.
Note!
