The change from summertime to wintertime, and vice versa, is made automatically. The
date of the earliest changeover can be readjusted should the relevant regulations
change.
The dates set for the change from wintertime to summertime, and vice versa, ensure
that on the first Sunday after that date, the time of day will change from 02:00 (winter-
time) 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.
For clock time operation, the following settings can be made:
• Autonomous (does not send and does not receive)
• Clock time from the bus: Clock time slave (receives the synchronization signal from
the bus)
• Clock time to the bus: Clock time master (sends the synchronization signal to the
bus)
