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:
Central Local
Window contact
Room operating mode
S
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.
