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 schedule and/or on local influences such as window
contact, presence detector, or room unit.
The illustration below shows how these influences are processed by the room controller
along with their priority:
Central Local
Window contact
Room operating mode
S
Presence detector
Room unit
Temporary
Comfort mode
• The influence of priorities 1 and 2 is equivalent to permanent states .
• The influence of priority 3 is treated as event .
The key point in time is the moment at which the state changes (edge).
If another source of third priority later changes the state, the last known change is
valid .
