5.5.6 LTE-Mode Examples
The following examples show two typical applications of the time schedule in
conjunction with local control of the room operating mode.
Rooms with neither a room unit nor a presence detector
The room operating mode in Rooms 1...3 of a building is determined by the
Room operating mode time schedule. Window contacts are fitted in all rooms.

• The rooms are used and controlled by the Room operating mode time schedule as
follows:
– Night setback from 17.00 to 08.00,
– Protection from 20.00 to 06.00
– Lunch break from 12.00 to 13.00 (Precomfort)

Rooms with a room unit (

The room operating mode in Rooms 1 and 2 of a building is determined centrally by the
Room operating mode time schedule.
Comfort mode is then initiated locally via the room unit (Room 1) or presence detector
(Room 2).
The following conditions are specified:
• Overall, the building is in use from 06.00 to 20.00
(Protection mode from 20.00 to 06.00 hours).
• Rooms 1 and 2 must be available from 08.00 to 18.00 hours (Precomfort)
