hi
I have a problem with My new thermostat that was installed by a nest pro but failed to run hot water.the person ho installed the thermostat blamed a faulty motorised valve from hot water tub.
I replaced that valve and problem still there,hot water is not coming on even if manually overriding nest transmitter and manually opening the valve,boiler is not turning on.
Reading some of few post here I noticed someone had the same problem and was advised to wire cables like my receiver with the difference that black cable should go in slot 3 and grey cable in 5.
Or anyone with knowledge can you please look at my pictures and tell me please if there is something wrong there.
Cheers
