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.

Operation according to controller setting	Temperature setpoint “remote control“ active
	T1   T2

Suitable remote control units are:
Telephone modem, manual switch, window contact, presence detector, central unit, etc

Enter temperature for active remote control

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

Proceed as follows to enter your settings

	Set slider to temperature for active remote control: Press  or  to set the desired temperature.

Factory setting: All DIP switches to					OFF

• A Sensor calibration: DIP switch 1
  • If the displayed room temperature does not match the measured room temperature, the temperature sensor can be recalibrated.
  • Set the DIP switch to ON and press the DIP switch reset button:
  • CAL symbol is displayed. The currently measured temperature flashes.
  • Press orrecalibrate by max. ± 5 °C.
  • Set the DIP switch to OFF and press the DIP switch reset button to save the settings
• B Setpoint limitation: DIP switch 2
  • The minimum setpoint limitation of 16 °C prevents undesired heat transfer to neighboring spaces in buildings featuring several heating zones.
  • DIP switch ON: Setpoint limitation 16…35 °C.
  • DIP switch OFF: Setpoint limitation 3…35 °C (factory setting).
  • Press the DIP switch reset button to save the settings.
• C Temperature display in °C or °F: DIP switch 3
  • DIP switch ON: Temperature display in °F.
  • DIP switch OFF: Temperature display in °C (factory setting).
  • Press the DIP switch reset button to save the settings.
• D Control behavior: DIP switches 4 and 5
  • The REV13… 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 differential (factory setting).
  • Press the DIP switch reset button to save the settings.
• E Radio clock: DIP switch 6
  • 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.
  • Note on synchronization
    • 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
  • Note on reception
    • 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
  • No reception
    • 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.
• F DIP switch reset
  • 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 andsimultaneously 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 buttonsornavigate the settings. Confirm settings by pressing.
• Press the operating mode selector to exit the engineering settings.

• Note 3:
  • 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

• Check the display. If there is no display, check the insertion and function of the batteries.
• The operating mode “Continuous comfort mode“ read the displayed temperature.
• Set the temperature setpoint higher than the displayed room temperature (see operating instructions).
• The relay and, as a result, the actuating device must switch at the latest after one minute. The 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.
• Set the temperature setpoint for operating mode “Continuous comfort mode“\to the desired value.
• Select the desired operating mode.

Reset

User-defined settings:

, and simultaneously for 3 seconds:

This resets all temperature and time settings of the program selection slider to default values (see also “Factory settings” in the operating instructions). The expert settings remain unchanged.
The clock starts at 12 p.m., the date on 01-01-08 (01 – January – 2008).
During the reset, all display fields are lit and can be checked accordingly.

All user-defined settings plus expert settings:

• Press the DIP switch reset button , andsimultaneously for 5 seconds:
• After the reset, all factor settings are reloaded. This applies to the program selection slider as well as to the expert settings.

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.
• The 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

Mounting and installation

• Begin installation by first attaching and wiring the base. You can mount the base on the 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.
