- Electrothermally controlled actuator for automatic opening/closing of thermostatic valves with M30x1.5 thread (e.g. standard valves on return manifolds in underfloor heating systems)
- The electrothermal head is controlled by a thermostat or a programmable ambient thermostat that, as required, opens or closes the head of the valve on which it is mounted
- Supplied with an additional clean limit switch contact (black and grey wires) that can be used in a de-energised state to control circulation pumps, zone valves, boilers or other equipment (if the system is designed to include the operation of another device)
- Supplied with a mechanical indicator that is visible through a transparent window, making it easy to see whether the valve on which the head is installed is open or closed
- Can be mounted vertically, horizontally or on the head (IP 54)
