Page 2 UFH4ZW – Installation Manual Description 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.

Page 5 E = Earth N = Neutral When an under- oor heating zone sends a call for heat to the UFH4ZW, the live & neutral output will supply 230v to the manifold pump/valve. It is recommended that this is fed through a high limit switch placed on the heating manifold, to protect against mechanical failure of the manifolds temperature control.
