DESIGO examples
The following examples show two typical applications of schedules and local control of
the room operating mode.
Rooms without room unit or presence detector
The room operating mode of rooms 1…3 in a building is determined by the two
schedules
Use
and
Occupancy
. Window contacts are installed in all rooms.
The following conditions are specified:
•
The building is in use from 06.00 to 22.00 (
Use
schedule). Outside this period the
opening of a window trips an alarm (2).
•
Rooms 1 ... 3 are used by the same tenant and are controlled by the common
schedule
occupancy
: Night setback is between 17.00 to 8.00 (
not occupied
), lunch
between 12.00 and 13.00 (
standby
).
•
In Room 3, the window is opened briefly once in the morning and once at night (1).
