The Wyndam UFH 230v 2-Wire NC Actuator Head is a 230v, 2-wire, normally closed (NC) electrothermal actuator designed to fit onto the valves of an underfloor heating manifold. It opens and closes individual circuits automatically in response to the room thermostat, giving each zone its own temperature control.
Being normally closed, the actuator keeps its circuit shut until it receives power from the wiring centre when the thermostat calls for heat, then opens to allow warm water through. The simple 2-wire connection keeps wiring straightforward at the manifold. Part of the Wyndam UFH range, it is designed to work with Wyndam manifolds and Quadrant 230v wiring centres.
Features & Benefits
• Normally Closed (NC): Circuit stays closed until the thermostat calls for heat.
• 230v Operation: Powered from a 230v wiring centre.
