Functional description
ECO operation
In many areas of the building it makes sense for the temperature to be set to a lower
ECO temperature at certain times rather than to heat permanently to the comfort tem-
perature. By connecting the input terminal
Ø
to 230 V, the temperature is reduced by
4 °C and the status LED lights up green. This should be controlled by a central clock.
Controller adaptation
Depending on the heating system, the control behaviour can be adjusted.
Pulse width modulated control (factory setting): The output is not permanently actu-
ated, but for a time period (pulse width) that depends on the difference between tar-
get and actual temperature. This method brings the actual temperature gradually
closer to the target temperature.
Two-point control: The output remains switched on until the selected target temperat-
ure has been exceeded by 0.5 °C. The output will not be switched on again until the
target value is undercut by 0.5 °C. Since most heating systems respond very slowly,
this type of control can entail temperature overshooting.

Operation
Increasing or reducing the floor temperature
￭
Turn the control knob to the right or left.
If the target temperature is not reached, the LED lights up red for a maximum
of 2 minutes (green = ECO). The indication can also take place during the en-
tire heating process (see Activating/deactivating permanent LED operation).
In the middle position, the device regulates to approx. 30 °C target temperat-
ure. The lowest target temperature is approx. 5 °C and the highest target tem-
perature is approx. 50 °C
