Hive heating again. Plumber removed wiring for thermostat!!

[RandomGrinch]

the control path in both has only the HW stat between the programmer and boiler.

The orange from the 3 Port is also in the control path...

The plumber needs to return and sort it out. Do not pay him until it is all working.

But doing nothing with the CH off


I was going to ask why you posted this incorrect drawing but adding the other parts around it makes the boiler enable totally clear when only Hive pin 3 is powered.

Ahh, I'm so sorry, I see where you're coming from now!

You quoted this from me..

If we knew the H/W wasn't working, we may have got there sooner.
The Hive controls the valve, but it is the micro switch within the valve, that tell the boiler to fire.

I should have been clearer and there should have been a break between the two sentences.

In my mind I was saying "you told us earlier the heating wasn't working but HW was, if you told us both had failed, we might have got their sooner"

And separately "going back to the heating not working, it's the micro switch in the valve that fires the boiler".

I'm afraid I hadn't realised I'd conflated the two, hence it took me a while to understand what you were getting at!

OK. we got there.

However the boiler not firing for hot water due to a faulty motorised valve...
