During startup, REV..DC synchronizes automatically to the time signal (DCF77) from
Frankfurt, Germany. Synchronization takes max. 10 minutes. Synchronization restarts
each time you press the button or move the program selection slider from the RUN
position during these 10 minutes. Siemens recommends to set the desired settings upon
startup, install the REV..DC in the desired location, and not carry out any actions on the
REV..DC for the next 10 minutes.
In normal operation, the REV..DC synchronizes to the radio clock every day at 3:10 a.m.
The time signal from Frankfurt is modulated to a radio signal. The reception of this radio
signal depends on the distance to Frankfurt, atmospheric conditions as well as the
location where the REV..DC is installed. Siemens cannot guarantee that the REV..DC
can receive the time signal from Frankfurt at any time and any place.
The radio clock symbol is deactivated and an error message is displayed if the clock was not
able to synchronize the time for 7 consecutive days. The controller then runs on the internal
quartz.
After you change one or several DIP switch positions, you must press the DIP switch
reset button to reset the DIP switch.
Otherwise, the previous setting remains active!

Code list
This entry has no effect if the radio clock either is inactive or not available.
The time signal received from Frankfurt is shifted by the value set in Code 30 (time zone)
if the radio clock is active.
The time is always changed over at 2 a.m. on the Sunday preceding the set date if there
is no radio clock or if it is inactive. The time change is shifted by the value set in Code 30
