The controller generates the 24-hour operating mode from the current 24-hour pro-
gram. It automatically selects the switch-on time of the first heating / cooling period and
the switch-off time of the last heating / cooling period to generate and display a com-
plete heating / cooling period. The comfort temperature used by the controller is the
currently stored standard setpoint of the continuous operating mode
generated 24-hour operating mode is maintained until another operating mode is se-
lected.

The switching program can be used as a 7-day or 24-hour switching program,
depending on programming. It is also possible to select one of the continuous operating
modes with which the switching program is not used.
With the 7-day switching program, it is possible to program all days individually, the
working days (1-5), the weekend (6-7), or the entire week (1-7).
When a heating / cooling period is programmed, 3 different switching patterns are
available.
It is possible to select 1, 2 or 3 heating / cooling periods.
For each heating / cooling period, the start time, end time and comfort setpoint are to
be entered. In between heating / cooling periods, it is always the same economy tem-
perature setpoint that is used. This economy temperature setpoint can be adjusted on
the temperature menu.
