The change from summertime to wintertime, and vice versa, is made automatically. The
date of the earliest changeover can be adjusted should the relevant regulations change.
The dates set for the change from wintertime to summertime, or from summertime to
wintertime, ensure that on the first Sunday after that date the time of day will change
from 02:00 (wintertime) to 03:00 (summertime), and from 03:00 (summertime) to 02:00
(wintertime).
If both dates are set to coincide, summer-/wintertime changeover will be inactive.

Communication

For the time of day, there are several sources available, depending on the master
clock. This can be entered on the controller. Time of day and date can be exchanged
via bus.
The following settings for clock time operation are possible:
• Autonomous (does not send and does not receive)
• Time of day via bus: Clock time slave (receives the synchronization signal via bus)
• Time of day on the bus: Clock time master (sends the synchronization signal to the
bus)
