room operating mode
Central control of room operating mode via the Use and
Occupancy time schedules
These time schedules are not supported by third-party S-mode. If they are used
nevertheless, this can cause room controller errors.
Central and local control of room operating mode
based on occupancy
The presence detector has two possible states:
• The room is occupied
• The room controller switches to Comfort
• The room is not occupied
• The room controller switches to Economy or Precomfort
• The change of effective room operating mode is event-driven, the key factor being
the moment when the effective occupancy changes.
• The room unit or Temporary Comfort mode (both Priority 3) can cause the effective
room operating mode to change again
(people leave room)
(people enter room)
Occupied" means: "Changes to Occupied"
The presence detector is connected directly to a digital input on the room controller
(see page 126); alternatively an EIB/KNX presence detector connected to the EIB/KNX
bus may be used (see diagram below).
The two inputs are OR-linked: If one signals presence, presence applies.
