Eh, er,Many thanks.
Am I right in saying to test whether the programmer has live, this will be done by opening the programmer or will there be a live in the junction box in the loft where the wires for the pump and valve are?
Obviously to test whether the 3 port valve is getting 240v this will be done at the junction box.
Would you test for continuity between programmer and 3 port valve or does the receives 240v when the programmer is turned on?
I think you need an electrician tbh.
With all due respect.
