Central and local control of room operating mode
based on occupancy
The central time schedule transmits the anticipated occupancy of a room or group of
rooms. It controls the room operating mode of a room controller while the building is in
use. Outside the building-in-use period, the time schedule is disabled.
The time schedule can be used, e.g. by a building tenant to specify occupancy times of
his or her rooms.
The occupancy schedule has three possible states:
• Occupancy expected.
• Room controller switches to Comfort.
• Occupancy is probable; the room must be ready for use shortly
( Comfort temperature).
• Room controller switches to Precomfort.
• No occupancy expected.
• Room controller switches to Economy.
A presence detector detects the presence of people in a room.
It controls the room operating mode of a room controller while the building is in use.
Outside the building-in-use period, it is disabled.
