Technical features
Control
Self-learning mode
Control algorithm
The REV200… is a 2-position controller providing PID mode. The room temperature is
controlled by the cyclic switching of a regulating unit.
The control generates the positioning signals according to the deviation of the adjusted
setpoint from the actual value acquired by the built-in temperature sensing element.
The rate of response of the plant depends on the selected control algorithm:
The factory settings produce a self-learning operating mode. The controller adapts
automatically to the type of controlled system (that is, type of building construction, heat
demand, types of radiators, size of rooms, etc.). After a certain learning period, the
controller optimizes its parameters and then operates in the mode it has learned.
In exceptional cases where the self-learning mode may not be adequate, it is possible
to select PID 12, PID 6 or 2-Pt mode:
PID 12 mode
PID 6 mode
Switching cycle of 12 minutes for normal or slow controlled systems
(e.g. massive building structures, large spaces, cast-iron radiators, oil
burners).
Switching cycle of 6 minutes for fast controlled systems (e.g. light
building structures, small spaces, plate radiators or convectors, gas
burners).

Parameter settings
Pure 2-position control with a switching differential of 0.5 °C (±0.25 °C)
for very difficult controlled systems with considerable outside
temperature variations.
The control algorithm is selected with DIP switches no. 1 and no. 2.
All basic settings are made with a number of DIP switches. The DIP switches can be
accessed by removing the unit from its base.
Every DIP switch setting must be confirmed by
pressing the DIP switch button, thus activating the
setting.

Operating modes
The controller has 4 different automatic modes with a choice of 24-hour
and 7-day programs.
In addition, 2 continuous modes without a switching program function
and one standby mode are available.
Switching program
By selecting the appropriate operating mode, the switching program can be used either
as a 7-day or 24-hour program. In addition, it is possible to select a continuous
operating mode, which does not make use of the switching program.
24-hour program
For the 24-hour program, there are 3 different switching patterns available. There is a
choice of 1, 2 or 3 switching cycles. Depending on the choice made, this switching
pattern is then repeated for every day.
At the switching points, both the time and the associated setpoint can be selected. A
specific setpoint can be selected for each switching point.

7-day program
The 7-day program offers different switching patterns for every day of the week. This
means that one of the three 24-hour switching patterns can be selected differently for
every day of the week, depending on the requirements. Like with the 24-hour program,
time and setpoint of every switching point can be different.
Override button
In the automatic modes, a manual change from normal to economy temperature can be
enforced via the override button. The selection will automatically be reset when the next
switching point is reached or when changing the operating mode.
Sensor calibration
If the temperature displayed does not agree with the room temperature effectively
measured, the temperature sensor can be recalibrated.
Calibration is activated with DIP switch no. 9 (sensor calibration ON) and a DIP switch
reset. The displayed room temperature can be brought in line with the room
temperature effectively measured, the increments being 0.2 °C (max. ±2 °C).
When sensor calibration is completed, the DIP switch must be reset to OFF and the
DIP switch reset button must be pressed.
Important
Optimum start control
Switch-on point P.1, which is the first switch-on point of the day, is brought forward
such that the selected sepoint will be reached at the desired time.
The setting depends on the type of control system in use, that is, on heat transmission
(piping system, radiators), building dynamics (building mass, type of insulation), and
heating output (boiler capacity, flow temperature).
Optimization can be set with DIP switches no. 6, 7 and 8.

Cooling
DIP switch no. 4 is used for switching over to cooling mode when used in cooling
applications.
Periodic pump run
The setting is made with DIP switch no. 5 while the pump is running. This protects the
pump against seizure during longer OFF periods. Periodic pump run is activated for
one minute every 24 hours at 12:00 h.
Setpoints
In the automatic modes, the setpoints can be entered for every switching point, and
individually in the continuous modes.
Limitation of setpoint
When using minimum limitation of the setpoint to 16 °C, undesired heat transfer to
neighbouring flats is prevented in buildings that have several heating zones. The
function can be selected with DIP switch no. 3.
Reset
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 correct functioning of the display to be
checked.
After each reset, all personal settings such as time of day, weekday, switching points,
temperature setpoints, holidays, sensor calibration, etc., must be reentered.
Holiday function
For the holiday function, the start day (maximum 6 days in advance), the duration of the
holiday period and the temperature setpoint must be entered. This means that when
absent for a longer period of time (up to 99 days), the plant can be switched to the
required economy temperature starting on the day of departure. Every midnight, the
counter subtracts one day. When the day counter returns to 00, the operating mode
selected last will automatically be resumed.
Mechanical design
Controller
Plastic housing with a large display which also serves as a touch screen. The display’s
lighting is switched on by touching the screen and switches automatically off after 15
seconds.
The controller (top section) can be easily removed from its base by pressing a button. A
hinged battery compartment cover facilitates the straightforward exchange of the two
1.5 V alkaline batteries type AA. The base can be fitted to all commercially available
recessed conduit boxes or directly on the wall and can then be wired before fitting the
controller to it. The housing accommodates the electronics, a DIP switch and a relay
with a potential-free changeover contact. The connection terminals are integrated in the
base.

Notes
•
•
In the event of a power failure at the REV-R…, the relay will be deenergized.
If in normal operation REV-R… does receive for more than 25 minutes a very weak
or no control telegram from REV200…, LED_1 starts to flash in red.
If control telegram is still understood correctly, receiver continues with normal
operation. If control telegram is not understood anymore, relay remains in last
position being switched to before.
As soon as REV-R… does receive any correct control telegram from REV200…
again, receiver continuous with normal operation
In case of error, REV-R… switches off relay approximately 60 minutes after
reception of last correct control telegram. The controlled device is also switched off
and LED_1 flashes in red.
As soon as REV-R… does receive any correct control telegram from REV200…
again, receiver continuous with normal operation
