A 4-wire actuator used on earlier Nu-Heat systems, both on individual control valves and manifolds.

  • Direct replacement for previous 4-wire actuators
  • Robust plated brass fixing collar
  • CE marked
  • 1m pre-wired 4 core flex for efficient installation

This is an electrically operated device that opens and closes the manifold valves. It is controlled by the room thermostat in the corresponding zone.

The 4-wire actuator incorporates an end switch to provide an electrical signal when it is in the fully open position. This is necessary with earlier control systems.
