The Heatit S-Control2 is an electronic thermostat designed for controlling electric and water-based heating systems. It offers four flexible functions: room thermostat, floor sensor thermostat, combined control, or power controller. This makes it suitable for underfloor heating, radiators, and other hydronic systems. With the integrated room temperature sensor and the ability to connect up to two external sensors, the thermostat can be customized to prevent overheating of sensitive floor coverings.

The device is equipped with innovative ZeroX technology, which ensures particularly gentle switching at 0 volts. This reduces wear and significantly extends the lifespan. Operation is convenient via a rotary knob with a temperature range of 5 to 40 °C. For applications in power controller mode, an additional 1–10 power selection switch is included.

Thanks to its compact design, the thermostat fits into standard flush-mounted boxes and is compatible with common System 55 frames. The stable metal frame construction ensures secure mounting in the box. The thermostat is suitable for continuous loads up to 16 A (resistive). For higher or capacitive/inductive loads, the use of a suitable relay is recommended.
