Building Technologies Room operating modes 2013-06-17
The presence detector has two possible states:
State Description
Occupied • The room is occupied
• The room controller switches to Comfort
Unoccupied • The room is not occupied
•
The room controller switches to Economy or Precomfort
The table below shows Effective occupancy as a function of the Occupancy time
schedule and the presence detector.
Principle: "Occupied" takes precedence over “Unoccupied“. If either the time schedule
or the presence detector transmits Occupied then the room is Occupied.

• The effective room operating mode can be changed by the effective occupancy only
during the building-in-use period (defined by the Use time schedule)
• The change in the effective room operating mode is event-driven, the key factor
being the moment at which the effective occupancy changes.
• The room unit or Temporary Comfort mode (both Priority 3) can cause the effective
room operating mode to change again the last command always applies.

Key: “ Occupied" means: "Changes to Occupied"
The following S-mode communication object is applicable when using the time
