A6V11545892_en--_a
The following examples show 3 typical applications for a central time schedule
together with local control of the room operating mode.
The room operating mode in rooms 1...3 of a building is determined by the time
schedule. Window contacts are installed in all rooms.
The following conditions are specified:
The rooms are used and controlled by the time schedule as follows:
● Night setback from 17:00 to 08:00 (Economy)
● Lunch break from 12:00 to 13:00 (Pre-Comfort)
The substitution (P910) for Pre-Comfort via bus is set on the thermostats as
follows:
● Room 1: Comfort (1)
● Room 2: Economy (0)
Window contact
In Room 1, the window is opened briefly, once in the morning and once in the late
afternoon (1). The opening in the morning and afternoon directly influences the
actual room operating mode.
During lunch break (2), the time schedule changes to Pre-Comfort. The mode
remains in Comfort as set by parameter "Transformation Pre-Comfort" (P910 = 1).
