Floor thermostat 1 Safety instructions Electrical devices may only be mounted and connected by electrically skilled persons. Serious injuries, fire or property damage possible. Please read and follow manual fully. Danger of electric shock. Always disconnect before carrying out work on the device or load. In so doing, take all the circuit breakers into account, which support dangerous voltages to the device and or load. Danger of electric shock. The sensor cable is connected to the mains voltage potential.
Floor thermostat 4 5 Product characteristics – Manually setting a comfort temperature for the floor – Manually switching off the temperature control – Input terminal for activation of reduction temperature (ECO) via central clock – External temperature sensor (remote sensor) – Frost protection function – Controller output working method: pulse width modulation (PWM) or two-point switchable – Interruption of heating for 5 minutes after one hour in continuous heating mode – Permanent LED ope
Floor thermostat 6 Operation Brief overview Function Change room temperature Display operating mode Control knob ... turn right or left ... press briefly Status LED * maximum 2 minutes LED colour Red = heating mode green = ECO heating mode 10 seconds. Orange = frost protection (10 seconds) Red = heating mode green = ECO heating mode Orange = frost protection * In permanent operation, the status LED lights up continuously during the active heating phase, but with reduced brightness.
Floor thermostat Activating/deactivating permanent LED operation In permanent operation, the status LED lights up continuously during the active heating phase. ￭ Press the control knob for longer than 10 seconds until the LED lights up or flashes in the colour magenta. LED lights up magenta = permanent operation is active LED flashes magenta = permanent operation is inactive (default setting) 7 ￭ Press the control knob briefly to switch the mode.

Observe the conductor cross-sections (see figure 3). ￭ Optionally, connect the ECO operation input Ø via a switching contact of a central clock (8).
Floor thermostat This setting can be used with most heating systems without adaptation. Changing the settings ￭ Press the control knob for longer than 20 seconds. The LED flashes green for PWM control and green/blue for 2-point control. ￭ Press the control knob briefly: The control behaviour is changed. ￭ Press the control knob for longer than one second. The current control behaviour is saved and the setting mode is exited automatically. After approx.
Floor thermostat ￭ Pull the control knob off the central plate so that the adjustment rings are visible Bild. Pulling off is done by hand or with a suitable tool, e.g. vacuum lifting tool or key cap puller. ￭ Turn the large blue adjustment ring clockwise to the desired minimum temperature. Each notch corresponds to a change of about 2 °C. ￭ Turn the small red adjustment ring anticlockwise to the desired maximum temperature. The respective adjustment ring can only be turned in one direction.
Floor thermostat The resistance values can only be measured if the sensor is disconnected. 9 Warranty The warranty is provided in accordance with statutory requirements via the specialist trade.
