Energy-efficient heating system control. The thermo-electric actuator from Sygonix can be quickly and easily installed in the heating system via a nut connection and controlled by a room thermostat. The advantage is clear: the actuator manages the interaction between thermostats and valves, significantly improving the efficiency of the heating system. Simple and safe. In its resting position, the actuator is closed. To ensure this even after a power failure, the Sygonix actuator features a spring return function. Particularly user-friendly is the visible position indicator for opening or closing the valve. The device is dust and splash-proof according to IP54 standards.
