What we all working on this week ?

Where does the grey wire go ?

To a “disused” room stat. Both greys fed into neutral load on spur, grey wire snipped at boiler end.

Ok, so basically, the installer assumed blue wire was neutral, L - N was approx 10Vac, N - E was approx 248VAc, L - E was approx 248Vac, so originally I assumed reversed polarity.

What was actually happening was blue wire in spur was switched Live, so boiler would only work with the old room stat that was left connected.

The stat was obviously left in a position where the boiler would operate, and was either turned by customer (said it hasn’t been touched), or it wouldn’t work, as temperature was high today.

Proud of my findings today though.

Job started Monday, stopped yesterday morning. Customer tested positive for Covid. Makes a real mess of scheduling.
But the sun is shining, can clean out the van and garage.
