Operating modes
The controller offers the two time switch programs and .
Enter a start time and end time for each heating phase. Also comfort temperature
setpoint can be freely entered for each heating phases. Between the heating
phases the controller always switches to the same, freely selectable energy saving
temperature setpoint.
The controller also offers the three 3 continuous modes comfort mode,
energy saving mode and frost protection mode.
You can freely adjust the setpoints for the weekly and 24-hour operating modes.
Setting range for all setpoints without setpoint limitation 3…35 °C.
Setting range for all setpoints with setpoint limitation 16…35 °C.

Three different switching patterns are available to simplify entry of switching times.
These can be assigned as blocks to the corresponding weekdays 1…5 and weekend
days 6…7. As a result, you need to adapt the switching times and room temperatures
only once for each block.

You can enter the beginning, temperature and end of your holidays. At the beginning of
the holidays, the controller switches to the desired holiday temperature and returns to
the previously set operating mode at the end of the holidays.
In holiday mode, symbol is displayed along with the end of holiday mode.
Proceed as follows to enter your settings:
Set slider to position 15 (start of absence): Press or to set the start date
for your holidays.
Set slider to position 16 (temperature during absence): Press or to set
the desired temperature while on holidays.
Set slider to position 17 (end of absence): Press or to set the end date
for your holidays.
RUN
Return the slider to position RUN. Symbol is displayed to the left of the
symbol.
Press , , , or move the slider to end holiday mode prematurely.
Remote control
Use a suitable remote control unit to activate the "Remote control" temperature
setpoint in the controller. Changeover takes place by making a potential-free contact
connected to terminals T1 and T2.
A flashing symbol indicates active remote control mode.
After the contact opens, the previously set operating mode is reactivated.

You can freely select the temperature for active remote control. Activating remote
control immediately enables control to the remote control temperature regardless of the
currently active operating mode. When you deactivate remote control, the controller
returns to the set operating mode.

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 4 ON and 5 ON: 1 h/°C For slow controlled systems.
DIP switches 4 ON and 5 OFF: ¼ h/°C For fast controlled systems.

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

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.
