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.

The REV17… is a two-position controller with PID control. The room temperature is
controlled through cyclic switching of an actuating unit.
DIP switches 4 ON and 5 ON: PID self-learning
Adaptive control for all applications.
DIP switches 4 ON and 5 OFF: PID 6
Fast controlled system for applications in locations with
large temperature deviations.
DIP switches 4 OFF and 5 ON: PID 12
Normal controlled system for applications in locations with
normal temperature deviations.
DIP switches 4 OFF and 5 OFF: 2-point
For complex controlled systems, simple two-position controller with
0.5 °C switching difference (factory setting).
Press the DIP switch reset button to save the settings.
Only applicable with controlled circulating pump or valve!
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).
Press the DIP switch reset button to save the settings.
Only applicable to REV..DC (with integrated DCF77 receiver to receive time signal from
Frankfurt, Germany)!
DIP switch ON: Clock run by controller-internal quartz.
DIP switch OFF: Time signal DCF77 from Frankfurt, Germany.
Press the DIP switch reset button to save the settings.
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
(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) Set the temperature setpoint higher than the displayed room temperature (see operating
instructions).
d) The relay and, as a result, the actuating device must switch at the latest after one minute.
Symbol ▲is displayed. If not displayed:
•Check actuating device and wiring.
•It is possible that in heating mode the room temperature is higher than the set
temperature setpoint.
e) Set the temperature setpoint for operating mode “Continuous comfort mode“ to the
desired value.
f) Select the desired operating mode.

Engineering
•Mount the room temperature controller in the main living room.
•Select the mounting place so that the sensor can acquire the air temperature in the
room as accurately as possible and without being influenced by solar radiation or
other heat or refrigeration sources.
•Mounting height is approx. 1.5 m above the floor.
•You can mount the unit on most commercially available recessed conduit boxes or
directly on the wall.
•Begin installation by first attaching and wiring the base. You can mount the base on
most commercially available recessed conduit boxes or directly on the wall. Then
insert the controller from top to bottom into the base.
For more information, see the installation instructions supplied with the unit.
•Comply with all local regulations on electrical installation.
•Wire separately the remote control contact T1 / T2 using a separate, shielded cable.
•Remove from the batteries the battery transit tab designed to prevent premature
activation of the unit: Select desired language by or . Confirm by .
•You can change the control characteristics using the DIP switch on the rear of the
unit.
•Set any thermostatic radiator valves to their fully open position, if present in the
reference room.
•Recalibrate the temperature sensor (see "Sensor calibration") if the displayed room
temperature does not match the room temperature measured.
This is a software class A controller designed for use at a normal degree of pollution.
