the apartment for a short period of time, thus saving energy.

The display indicates the change. It is valid only until the next switching time.

Activate party mode: Press the button for 3 seconds.

Party mode is available only in operating modes and . In party mode,

the controller controls to a freely selectable temperature for a freely

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.

etc.

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.

A flashing symbol indicates active remote control mode.

After you change one or several DIP switch positions, you must press the DIP switch reset button to reset the DIP switch (see

also Fig. ). Otherwise, the previous setting remains active!

Factory setting: All DIP switches to OFF

If the displayed room temperature does not match the measured room temperature, the

temperature sensor can be recalibrated.

Set DIP switch to ON and press the DIP switch reset button:

CAL symbol is displayed. The currently measured temperature flashes.

Press or to recalibrate by max. ± 5 °C.

Set DIP switch to OFF and press the DIP switch reset button to save the settings.

The minimum setpoint limitation of 16 °C prevents undesired heat transfer to

neighboring spaces in buildings featuring several heating zones.

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

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) Set temperature setpoint to maximum (see operating instructions).

d) After 1…5 minutes, the relay to open the actuator must switch on. Symbol is

displayed. The actuator OPENS. If not:

∂Check actuating device and wiring.

∂It is possible that the room temperature is higher than the set temperature setpoint.

e) Set temperature setpoint to minimum (see operating instructions).

f) After 1…5 minutes, the relay to open the actuator must switch off and the relay to close

the actuator must switch on. Symbol is displayed. The actuator CLOSES. If not:

∂Check actuating device and wiring.

∂It is possible that the room temperature is lower than the set temperature setpoint.

g) Set the temperature setpoint for operating mode “Continuous comfort mode“ to the

desired value.

h) 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

,and simultaneously 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.

The controller starts with an initialization phase of 180 seconds after each reset. In

this phase, the actuator is driven to the basic position CLOSED.

Important: Driving the actuator to the fully CLOSED position takes max. 150

seconds. After a reset, reinsert the controller in the base within

30 seconds.
