Safety instructions
Only authorised electricians are permitted to work on a 230 V mains voltage. The safety regulations
of the VDE and the local electrical utility company must be observed
The connection work stated in these instructions must not be carried out when the mains voltage is
switched on.
A 30 mA residual current circuit-breaker must be used in humid areas (such as bathrooms) in
accordance with VDE 0100.
The mains supply must be protected by means of a miniature circuit-breaker (16 A).
A terminal cross-section of 2.5 mm2 must be used for a heating output of 3 kW or higher.
Description/application range
The electronic temperature controller with timer control is designed for controlling the floor
temperature and/or the room temperature in individual rooms.
It can be used, for example, for electrical direct heating (floor or convectors), supplementary heating
for floor background heating in bathrooms, electrical perimeter heating or warm water heating with
control valves. The controlled variable is either the room temperature using an integrated room
temperature sensor or the floor temperature using the supplied floor temperature sensor at the level
of the heating mat.
AC 230V normally closed control valves are used for the control of warm water heating systems.

Installation instructions - Mounting options
Installing the floor temperature sensor
Install the floor sensor in a separate protective tube at the heating mat level centrally between the
heating cables.
ATTENTION: Apart from when only room temperature control is required, a floor temperature sensor
must always be connected. Failure to do so will turn off the heater.
With room temperature control systems with floor heating, it must be ensured that the floor is not
overheated. With the universal controller it is possible to implement a temperature monitor function
(floor temperature monitoring) by using the floor sensor (default setting). The floor limit temperature
that is not to be exceeded can be set in the controller.
(see “Changing controller options”)
Installing temperature controllers
Installation in standard conduit box. When using additional intermediate terminals
the use of a deep conduit box is recommended.
Mounting height: Approx. 1.5 m above floor.
Avoid exposure to water.
When used as a room temperature controller, ensure that normal room air reaches the controller
without obstruction. The controller should not be mounted in shelf walls, under curtains or on outdoor
walls.
External heat from sunlight and draughts from windows and doors impair the accuracy of the
controller and should be avoided.
The frame can be exchanged for switch frames (if required with intermediate frame) from Busch-
Jaeger, Berker or similar, in order to adapt the controller to different switch systems

Commissioning
If a room temperature controller is to be used as a cooling controller, remove jumper 1 (figure 7) with
a long nose pliers and fit it in the two upper sockets. To deactivate the smart function remove jumper
2 (figure 7) and fit it into the two sockets on the right.
The universal controller is factory set as a floor temperature controller (10 to 60°C).
For changes see “Changing controller options”. If you have moved a jumper or changed the rotary
switch setting on the universal controller, the Reset button must be pressed after the und cover is
fitted and the mains voltage is switched on.
Then set the Heating On/Off switch on the controller to the
position (Figure 1). Setting the time and weekday (see “Programming”)
Move the switch to the required position.

The display shows the current heating program
and the current time. The bar corresponding to
this time flashes at the same time.
For other heating programs see
“Programming”
Long bars = Heating temperature
Short bars = Setback temperature
The controller switches to heating operation at the indicated times (long bars).
In other words, heating will be activated until the heating temperature set on the dial is reached, when
it is then kept constant by the controller. At the other times, the device regulates the temperature to
the setback temperature value, i.e. the heating is switched back on if it goes below the defined
setback temperature (default 15 °C).
For changing the setback temperature, see “Changing the setback temperature”
Setting the required setback temperature with the adjustment dial (Figure 1)
With floor temperature control 10 to 60 °C (numbers on the adjustment dial 1 to 6)
1 = approx. 10 °C ; 2 = approx. 20 °C etc.
With room temperature control 5 to 30 °C (numbers on the adjustment dial 1 to 6)
1 = approx. 5 °C ; 2 = approx. 10 °C etc.
Note The heating temperature cannot be shown on the display.

Mains supply failure
The heater switches off in the event of a mains supply failure and the upper bar of the
display flashes. The device resumes its previous operation if the mains voltage is restored within
approx. 1 to 1 ½ days. If the mains supply failure is longer, the time and weekday must be reset and
the 'E' user program may have to be re-entered. The set-back temperature must also be
reprogrammed if this was altered.
Short-circuit or interruption in the sensor line: The heating system is disconnected and the LED
flashes. CAUTION: In the event of a fault, the mains voltage may still be present on the sensor line
Special master controllers for connecting satellites
All controllers listed can be supplied as master controllers for connecting satellites. The TA output can
be used to connect virtually any number of clockless temperature controllers, e.g. commercially
available bimetal controllers with their L set-back input TA as satellites. If the master controller with its
timer switches to set-back operation, all satellites do the same.
