The thermostat is designed for operating a three or four-way mixing valve with the option to connect an additional valve pump. The controller is equipped with weather-based regulation, weekly regulation, and also works with a room regulator. An additional advantage of the controller is the return protection function, which prevents water from boiling in the short boiler circuit and protects against very low water temperatures returning to the boiler.

It can cooperate with two additional valve modules, allowing control of a total of three mixing valves.
