Room thermostat with white illuminated display, screw fixing only and without claws.
The control method depends on the type of heating and is determined by the installer:
The heating is turned on when the room temperature falls below the set target temperature (measured with an internal sensor or external remote sensor).
The underfloor heating is turned on when the floor temperature falls below the set target temperature (measured using an external remote sensor).
The room temperature is measured and regulated using the internal sensor. An additional external remote sensor is 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 this range, the heater is turned on, and if the temperature is above this range, the heater is turned off independent of the current room temperature.
External sensor ref.-no.: FF 7.8
