Polypipe 4 Zone & Hot Water Wiring Centre UFH4ZW

The UFH4ZW is an 4 Zone Hot water wiring centre for use with Polypipe 230v thermostats.

The UFH4ZW can be used to control any actuator or valve which requires a 230v AC signal to open. For mid position valves and those requiring a closing signal, a changeover relay is required. 

At the same time the UFH4ZW oers the ability to operate a boiler or other heat source through a volt free output.An additional output designed for use with underoor heating systems, is also included as standard. 

This is the pump/valve Output, which would normally operate a manifold pump or a manifold valve.The H/W output provides a 230v hot water enable signal to the valve, the auxiliary wires of the valve are wired to the Gr and Or terminals.Zone 4 can be used as an isolated radiator zone by using the Yes/No switch. 

If the switch is set to NO; When zone 4 calls for heat this will provide an output to a radiator zone valve and the boiler but WILL NOT enable the underoor heatingpump/valve output.
