The radiator actuator is an electronic radiator thermostat that exchanges the set and actual temperature with the HomePilot via radio. It operates based on Z-Wave technology and can only be integrated into the HomePilot using the USB stick 8430. In conjunction with the HomePilot, the radiator actuator enables the regulation and automation of room temperature. Manual operation is still possible via buttons on the device. The adjustable range is between 4 and 28 °C. It synchronizes with the HomePilot every 5 minutes and automatically adjusts the regulation frequency according to the room size. Additionally, the radiator actuator features a window opening detection that reduces the radiator output when the temperature drops.
