DuoFern radiator actuator for controlling radiators automatically and energy-efficiently The DuoFern radiator actuator is a smart home radiator thermostat that is connected to HomePilot® and controls the radiator by means of the target temperature obtained by radio waves via HomePilot®. The thermostat has its own sensor. Practical functions such as the boost function (short-term heating of the room), antifreeze detection (prevents cooling below 4 °C) and valve protection (protection against calcification) are some of the useful functions. The thermostat’s display can be rotated by 180° and is illuminated. Coupling the thermostat with DuoFern door/window contacts allows the heating to be automatically turned down during ventilation. The programmable heating times allow you to create a heating profile, which provides the desired room temperature on the basis of a specified sequence. If the actuator is connected to HomePilot® and the latter is connected to an Internet router, you can make
