Setting the clock
•
Automatic changeover from summer- to wintertime, and vice versa
•
Fast and easy-to-understand time settings
•
Leap years are taken into consideration
To ensure correct operation of the switching programs, the time of day, weekday, date
and year must be correctly set.
Knowledge of date and year also allows the controller to provide automatic summer- /
wintertime changeover, to consider leap years and to ensure the correct triggering of
the holiday program.
The time of day can be set from a remote location via the bus system, provided clock
operation is appropriately set. Also refer to clock operation on operating line 865.
