Structure of the device

The control method depends on the type of heating
and is determined by the installer:
– Room temperature controller: The heating
(1)
is turned on when the room temperature
(2)
falls below the set target temperature
(3)
(measured with an internal sensor or external
remote sensor).
(4)
– Floor temperature controller: The underfloor
heating is turned on when the floor temperature
falls below the set target temperature
(measured using an external remote sensor).
(5)
– Room temperature controller with a limiter:
(in conjunction with underfloor heating):
The room temperature is measured
(6)
and regulated using the internal sensor.
An additional external remote sensor is
(7)
connected to measure the floor temperature,
and a target temperature range for the floor
is set. The room temperature control is
deactivated when the floor temperature is
outside of this range. If temperature falls below

Basic information
Four buttons below the display are used to operate
the temperature controller (Fig. 2, items (13) to (16)).
In the menu, you can activate operating modes
and make settings. If a button is not pressed for
more than three minutes, the unit automatically
switches back to the previous function and the basic
display (Fig. 2).
Operation when the controls are removed
The unit can also be operated when the controls are
removed. The current temperature is not displayed,
the "heating mode" display flashes, and the display
is not illuminated. If a button is not pressed for more
than three minutes, the display goes dark.
