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!
