DESIGO examples
The following are examples of two typical applications of time schedules in conjunction
with local control of the room operating mode.
Rooms with neither a room unit nor a presence detector
The operating mode of Rooms 1 … 3 in a building is determined by the two time
schedules
Building use
and
Room occupancy
. Window contacts are fitted in all rooms.
The following conditions are specified:
•
Overall, the building is in use from 06.00 to 22.00 (
Building use
time schedule).
Outside this period the opening of a window will trip an alarm (2).
•
Rooms 1…3 are used by the same tenant and controlled by the same O
ccupancy
time schedule. Night mode is to operate from 17.00 to 08.00
(Unoccupied)
and the
lunch break is from 12.00 to 13.00
(Standby).
•
In Room 3 the window is opened briefly, once in the morning and once at night (1).
