Setting the clock
Automatic changeover from summer- to wintertime, and vice versa.
Fast and easy-to-understand time settings.
To ensure proper operation of the heating program, the 24-hour time switch with the
time of day and weekday must be correctly set.
Between setting of date (line 3) and setting of weekday (line 2) there is no link. This
means that when the set date falls on a Wednesday, for example, Wednesday as a
weekday must also be set.
Automatic summer- / wintertime changeover adapts the time of day automatically. Also
refer to "summer- / wintertime" in Index.
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 mode" in Index.
