3 Function
The time-controlled thermostat allows the room temperature to be controlled in automatic mode
depending on the time and weekday (program) so that the heating requirements can be
adjusted according to individual lifestyles. The automatically controlled temperature can also be
adjusted manually as required.
The device is controlled by the measured value of the internal sensor. When the temperature
falls below the programmed value, the room is heated. in addition, an external sensor can be
connected for measuring the floor/room temperature.
The thermostat process can be adjusted according to the heating type:
–Room thermostat
The heater is switched on if the room temperature falls below the preset default value.
–Floor thermostat
The floor temperature is controlled. The heating is switched on if the room temperature
(measured by the external thermostat) falls below the default value.
–Room thermostat with limiter
The room temperature is controlled, the floor temperature (measured by the external
temperature sensor) is limited independent of this. The heater is switched on when the
room temperature falls below the preset default value.

Keep pressing the +/– push-button repeatedly until the desired temperature is displayed.
Press the OK (11) push-button to save the displayed temperature.
The device returns to the basic display.
The readout AUTO– indicates that the manually adjusted setpoint temperature deviates
from the temperature stored in the time temperature program. The temperature is
controlled according to the changed setpoint temperature until the next event.
Switch off controller
The device is in the basic display.
Keep the Menu/spush-button (8) pressed for 10 s.
The display first returns to the menu. The device returns to the basic display after 10 s. The

5 Information for electricians
5.1 Assembly and electrical connection
DANGER!
Touching live parts can result in an electric shock.
An electric shock can lead to death.
Disconnect connecting cables before working on the device and cover all live
parts in the area!
Installation location
To enable optimum room temperature control using the internal sensor, the installation location
selected should
–allow free air circulation
–not be located behind curtains, cupboards, shelves, etc.
–not be exposed to direct sun light
–be free of draughts
–not be on external walls
–be approx. 1.5 m above the floor
Connecting and mounting the device
Remove operating unit from the insert.
Strip a max of 8 mm from connecting cables.

Figure 7: Mounting
Align insert (7) in the connector socket and fix it into position with fastening screws (20).
Mount the insert in such a way that the plastic tongue (19) acts as insulation for the
fastening screw. (Figure 7)
Mount the design frame (5) and fix it into position by attaching the operating unit (3).
Connecting external temperature sensor
An external temperature sensor is required for the thermostat process of the floor thermostat
and thermostat with limiter. It is advisable to lay the temperature sensor in a protective pipe so
that it can be replaced later.
The wire of the temperature sensor supplies mains voltage and can be extended to 50 m
using suitable wires.
To avoid signal disturbances, do not lay the wire of the temperature sensor together with
mains cables.
Strip a maximum of 8 mm from the temperature sensor wire.
Connect temperature sensor according to connection diagram (Figure 6, 18).
Figure 8: Terminal for connecting the temperature sensor
When using flexible wire, insert and remove the wire release button (21) with an
appropriate tool.
5.2 Commissioning
CAUTION!
Malfunction of the heating system with incorrect controller settings.
The heating system could get damaged.
Only allow settings of the heating system to be carried out by a skilled specialist.
