tivate programming mode via the following operating line.

Clock time operation
If the system should use a common time of day, one of the devices must be
defined as the clock time master and the others as slaves.
Main menu > Commissioning > Bus communication
> Time of day/date > Clock time op:
Autono-
mous
The central apartment unit clock runs autonomous. No time is
received or sent. (Factory setting)
Slave Central apartment unit clock is clock time slave and synchro-
nized to the master clock time.
Master Central apartment unit clock is clock time master.
Make sure that only one device in the system is defined as the clock
time master.
In plants with consumption data acquisition, we recommend setting
OZW772 as clock time master and all central apartment units to clock
time slaves.
Remote setting clock slave
Function “Remote setting clock slave = Yes“ allows you to also set the time of
day and the date on a clock time slave.
The new values are transmitted to the clock time master via the KNX bus. The
clock time master distributes the new time to all bus users. Thus, for the plant
user, operation is the same as that on the clock time master.
Main menu > Commissioning > Bus communication
> Time of day/date > Rem set clock slave:
No Clock time and date cannot be adjusted on the clock time
slave.
Yes Clock time and date can be adjusted on the clock time slave.
(Factory setting).
