Room thermostats: Optimized control alogorithm for underfloor heating and cooling

Whether surface or flush mounted, for heating only or for heating and cooling, with or without time program, our full range of room thermostats fulfils many special requirements you may have. The embedded temperature control algorithms are specially developed for underfloor temperature control resulting from extended climate chamber testing at our Technical Center in Germany. Designed and tested to provide the desired comfort with minimal temperature fluctuations, hence, doing its job unnoticeably but with high efficiency. The optional smart start-stop feature is another proof that optimized comfort and low energy consumption are no contradictions if you know how.

Flush mounted thermostats

Without compromising on the optimized room temperature control characteristics our flush mounted thermostats provide excellent design value at a minimum of space.

That is know how too.

Surface mounted thermostats

Our range of Alpha direct room thermostats were designed for daily use with the future in mind: advanced control technology is united with a high level of comfort control in an attractive, timeless and modern design incorporating a user-friendly intuitive operation philosophy.

Standard: Heating

The Alpha Thermostat direct Display is a high-quality room thermostat for the control of the desired room temperature for optimized user comfort. A simple single-room control system is possible with directly connected actuators. The setting of the desired room temperature, and the operation, can be performed comfortably via a rotary control with rotary-push action and soft ratchet. The well-structured and language-neutral using symbols only.
