Product details

The wireless radiator actuator 2 is an electronic radiator thermostat. It operates based on DuoFern wireless technology, can be integrated into a smart home, and is controllable via the SmartHome Box or the room thermostat. With an internal sensor, it can also be used as a stand-alone solution. When combined with the room thermostat, an independent system is possible. Optionally, the measured temperature from the room thermostat can be used for regulation. It features a boost function, frost protection detection, valve protection, and a child safety lock. The display, which is illuminated, can be rotated 180°. The radiator actuator allows for the regulation and automation of room temperature in conjunction with the SmartHome Box or the room thermostat. Manual operation is still possible via buttons on the device. The adjustable range is between 4 and 28 °C. It synchronizes with the SmartHome Box or the room thermostat. Additionally, the radiator actuator has an internal window opening detection feature that reduces heating when the temperature drops. It operates on two AA (Micro) batteries, each with 1.5 V, and has a supply voltage of 3 V.
