This function protects the pump or valve during extended OFF periods against possible
seizure caused by liming. Periodic pump run is activated every 24 hours at 12 p.m. for
three minutes (symbol ▲is displayed during active pump run).
DIP switch ON: Pump run On.
DIP switch OFF: Pump run On (factory setting).

Optimization advances the switch-on point P.1 to ensure that the selected setpoint is
reached at the desired time. The setting depends on the controlled system, i.e., on heat
transmission (piping system, radiators), building dynamics (building mass, insulation),
and heat output (boiler capacity, flow temperature).
DIP switches 7 ON and 8 ON: 1 h/°C For slow controlled systems.
DIP switches 7 ON and 8 OFF: ¼ h/°C For fast controlled systems.
DIP switches 7 OFF and 8 ON: ½ h/°C For medium controlled systems.

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!
Access to the expert level
Set the program selection slider to RUN. Press and simultaneously for 3 seconds, release the buttons, and
within 3 seconds press and hold down and simultaneously for 3 seconds, release , and press for another 3
seconds. This releases the engineering settings. is displayed.
The display first shows language selection with Code 00. Press the buttons or to navigate the settings.
Confirm settings by pressing .
Press the operating mode selector to exit the engineering settings.
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
(time zone) when the radio clock is active.
The time is always changed over at 3 a.m. on the Sunday preceding the set date if there
is no radio clock or if it is inactive.
Functional check
a) Check the display. If there is no display, check insertion and function of the batteries.
b) Operating mode “Continuous comfort mode“ , read displayed temperature.
c) REV.. in heating mode: Set the temperature setpoint higher than the displayed room
temperature (see operating instructions).
REV.. in cooling mode: Set the temperature setpoint lower than the displayed room
temperature (see operating instructions).

Engineering
•Place the room unit in the main living room by considering the following aspects (wall
mounting or free placement using stand).
•The distance to the receiver may not exceed 20 meters or 2 floors.
•Choose the place of installation so that the sensor can capture the air temperature in
the room as accurately as possible without being adversely affected by direct solar
radiation or other heat or cooling sources (about 1.5 meters above the floor for wall
mounting).
