SpeedComfort Automatic sensor

Automatic sensor for your radiator fans 

The Automatic Sensor is made for everyone who wants comfort without any hassle. Once you’ve placed your SpeedComforts, it takes care of the rest. When your radiator heats up, the fans switch on automatically. When it cools down, they turn off again. 

It’s whisper-quiet – at just 20 dB you’ll hardly hear it, but you’ll feel the difference right away. Within minutes, you’ll notice your room warms up faster and the heat spreads evenly. 

And the best part? It does everything by itself. All you have to do is enjoy the warmth.

Unobtrusive and seems to work well, but will only really be able to tell when the weather gets cold

About the Control Sensor 

Besides the Automatic Sensor, you can also choose the Control Sensor. While the Automatic takes care of everything on its own, the Control lets you decide how active your SpeedComforts are, from extra quiet to powerful.
