- Electrothermal-controlled servomotor for automatic opening/closing of thermostatic valves with M30 x 1.5 thread (e.g. normal valves on return-line manifolds of underfloor heating systems)
- The electrothermal head is controlled with a thermostat or an ambient programmable thermostat, which, as requested, opens or closes the head of the valve on which it is fitted
- Comes with auxiliary clean limit switch contact (black and grey cables) to use without voltage to control circulators, zone valves, boilers or other (if the logic of the system includes operation of another device)
- Comes with a mechanical gauge, visible through a transparent window, which makes it easy to know whether the valve on which it is installed is open or closed
- Can be fitted vertically, horizontally or upside down (IP 54)
