Rewire Problem

[Midwest]

Would it not be best for the OP to show what system he has installed first, before advice is given how to wire it up?

 

[Lucien Nunes]

It would, however given that the common terminals of the old controller were linked to line, it should be a straight swap. As I mentioned, if there is any doubt about the identity of the conductors, it's a different ball game, and it would probably be wise to call in an expert.

I am confident now it's a Y-Plan system as I have a Y-Plan 3 position diverter valve. I also know all the wiring colours for the pump and immersion thermostat so maybe better off requiring it from the start. Thanks again for your help.

Ok turns out the spare blue was in fact a neutral so now all back up and running again.

Thanks again for everyone who assisted I really do appreciate it and am very grateful !!
