Hi Gasmk1. The existing Polypipe motor uses all 5 wires so I plan on changing the valve to a Honeywell V4043H 2port which also uses 5 wires. The new motor comes with the valve so Ill check if the motor fits on the existing Polypipe valve or not. With a quick drain, should be easy enough to fit both parts and wire up. Thanks again.

Hey Gasmk1, hope all is well. FYI - I changed the motorised valve and guess what? It all works now. Everyone in the household are happy with warm feet! Thanks.
