Plastic casing with a large display which also serves as a touch screen. A hinged bat-
tery compartment cover facilitates the straightforward exchange of the two 1.5 V alka-
line batteries type AA. The base can be removed and fitted to all commercially available
recessed conduit boxes or directly on the wall, to be wired before the control- ler is
fitted. The casing accommodates the electronics with a ',3switch and a relay with a
potential-free N.O. contact. The connection terminals are integrated in the base.

Pressing one ofthese buttons forless than one second produces a step ofone
minute (time settings) or of0.2 °C(temperature settings).
Pressing formore that one second means quick adjustment which can be cancelled
again by pressing the button repeatedly.

. Press to adjust the setpoint temperature of each operating
mode.
Press the temperature button and then to readjust the displayed tem-
perature in increments of 0.2 °C (max. ±4 °C) to the room temperature temporarily re-
quired. The warmer ,colder function can be applied to all three temperature setpoints,
but the values thus changed will be reset again when the next switching point is
reached.
Press the time button and then to set the correct time of day.
The two switching points forthe 24-hour operation with one heating period and the four
switching points forthe 24-hour operation with two heating periods can be entered
individually and independently.

Select the economy temperature and press the time button, then enter the num-
ber of days you are absent (max. 99 days). The display will show the num-
ber of days and the holiday symbol. Every midnight, the counter subtracts one day.
When the day counter reaches 00, the 24-hour operation with two heating phases will
automatically be resumed.
Press the day counter and set it to 00.
If the temperature displayed does not agree with the room temperature effectively
measured, the temperature sensor can be re-calibrated. For that purpose, set the DIP
switch for Sensor Alignment to ON and press the DIP switch button.
Press to bring the flashing room temperature in line with the room temperature
currently measured. The increments for the readjustment are 0.2°C {max. ±2 °C).
When balancing of the sensor is completed, the DIP switch must be reset to OFF.
Before cleaning the display or to prevent tampering, the display buttons can be locked.
Press the button behind the little hole for a short moment (max. 1 second): ap-
pears and all other displays disappear. The display buttons are now disabled while all
the other functions are fully maintained.
Press the button behind the little hole again (max. 1 second).
Keep the button behind the little hole depressed for at least 3 seconds. This resets the
individual settings and the time of day to their default values. During the reset time of 3
seconds, the display will be fully lit, allowing the proper functioning of the display to be
checked. After each reset, all personal settings such as time of day, weekday, switch-
ing points, temperature setpoints, sensor calibration, etc., must be re-entered.
About three months before the batteries are exhausted, the display shows the battery
symbol . The other displays disappear, the display buttons are deactivated while
all the other functions are fully maintained. When changing the batteries, the current
data will remain stored for at least one minute.
Using a suitable remote operating unit, the REV100 can be switched to economy mode
. Changeover takes place by closing a SRWHQWLDOIUHHFRQWDFW connected to terminals
T1 and T2. In that case, symbol appears on the display. When the contact opens,
the selected operating mode will be reactivated.

Every Dip switch setting must be confirmed by pressing the Dip switch button.
Minimum limitation of the setpoint to 16 °C in buildings with several heating zones pre-
vents heat from being transferred from one apartment to another. The function can be
selected with the ',3switch.
The REV100 is a two-position controller providing PID mode. The room temperature is
controlled by the cyclic switching of a regulating unit.
The controller comes with an activated self-learning operating mode, which means that
it automatically adapts to the type of controlled system (type of building construction,
type of radiator, size of room, etc.). On completion of a certain leaming phase, the con-
troller automatically optimizes its parameters and then operates based on the mode
learned.
In exceptional cased where the self-learning mode does not represent the optimum
solution, it is possible to choose PID 12, PID 6 or the two-position mode.
PID 12 mode 12-minute switching cycle for normal to slow controlled systems (e.g.
massive houses, larger spaces, cast iron radiators, oil burner)
PID 6 mode 6-minute switching cycle for fast controlled systems (e.g. light building
structures, small rooms, plate radiators ,convectors, gas burner)
2-Pt mode Pure two-position controller with a switching differential of 0.5 °C
(± 0.25 °Cfor very difficult controlled systems with extreme outside
temperature variations

•When installing the controller, the base must first be fitted and wired. Then, the unit
can be engaged at the top, swung downward and snapped on
•For more detailed information, refer to the installation instructions supplied with the
unit
•For the electrical installation, the local safety regulations and standards must be
complied with
•The remote control contact T1/T2 must be wired separately, using a shielded cable
•The battery transit tab, which prevents inadvertent operation of the unit during trans-
port and storage, must be removed
•The control characteristic can be changed with the DIP switch located at the rear of
the unit
•If the reference room is equipped with thermostatic radiator valves, they must be set
to the fully open position
•If the room temperature displayed does not agree with the measured temperature,
the sensor should be re-calibrated (refer to section "Calibration of sensor").
