4 Wire 230V Actuator for Underfloor Heating Manifolds

A 4 wire 230V thermal actuator for underfloor heating manifolds. The additional wiring provides an auxiliary switch connection, which is typically used to signal the pump or boiler when a zone calls for heat.

Specify this version where your wiring centre or control strategy needs that feedback from the actuator rather than from the wiring centre itself.
