5.3 Determine the room operating mode with
DESIGO (S-mode)
In S-mode, the Effective room operating mode of the room controller depends on the
central schedules for Use and Occupancy and/or on local influences such as window
contacts, presence detectors, or room units.
The illustration below shows how these influences are processed by the room controller
along with their priority:
Central Local
Window contact
Building use
S
Occupancy
S
Presence detector
Room unit
Temporary Comfort mode
• The effects of Priority 1 and Priority 2 are similar in nature to states , which apply
continuously
• 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 .
