Room thermostat S1, Underfloor Heating, LK

Room thermostat S1, Underfloor Heating, LK

Art. no.: 2417287

Electronic, soundless room thermostat with Triac outlet and electronic feedback. For the best energy efficiency the room thermostat works with so-called self-modulating technology via signal pulsing to the valve actuators. The self-modulating technology adapts the underfloor heating output in relation to the set temperature. When the room temperature gets close to the set temperature, the output is reduced to avoid excessive temperatures.
