Control sensor

SpeedComfort Control sensor

The smart sensor that puts you in control.
With the Control sensor, you decide how your SpeedComforts respond. Choose easily between three modes – Zen (quiet & efficient), Balanced (everyday use) and Boost (extra power on cold days).
The sensor accurately measures your radiator’s temperature and reacts instantly, keeping warmth evenly distributed and your room comfortable in no time.
The Control sensor is also perfect for low-temperature systems, such as (hybrid) heat pumps. Even at lower water temperatures, the fans switch on at the right time to maintain high efficiency.
For anyone who wants more control over their indoor climate or aims to fine-tune their heating system, the Control sensor is the logical next step.
Smart, efficient and whisper-quiet – exactly what you’d expect from SpeedComfort.

I can fine-tune the fans perfectly. Boost in the morning to warm the room quickly, then Zen to keep it quiet.

The living room heats up faster, and I lowered the boiler temp to 60 °C with no comfort loss. Good for my bill and the planet.

Smart sensors; smart comfort!

The link between comfort, control and savings.

SpeedComfort sensors are the heart of your radiator fans. They ensure the fans know exactly when to switch on or off, so you always enjoy perfect comfort with minimal energy use.

A sensor measures the temperature of your radiator or the water flowing through it. Once it’s warm enough, it automatically activates the fans. This spreads the heat faster, warms the room more quickly and allows your heating to switch off sooner.

Whichever sensor you choose, the result is the same: warm faster, while saving energy.

That’s how you get the most out of your SpeedComforts all year round — from cosy winter days to refreshing summer nights.

SpeedComfort Automatic sensor

Simple, reliable and efficient.

The Automatic sensor is designed to make your life easier. Once installed, it works completely on its own: as soon as your radiator gets warm, the fan switches on automatically. It quickly and evenly spreads the heat throughout the room — no effort required.

Thanks to its smart automatic operation, you instantly enjoy more comfort and efficiency from your heating. The sensor maintains constant airflow, helping rooms reach the right temperature faster and saving energy.

In short: the Automatic sensor offers ease, reliability and maximum performance.
