heating problem

[1878]

room stat cover has been missing for a while!!! decided to change today as wires exposed....

there was one cable there, twin and earth 3 core, a live, neautral and an earth....

switched my spur off and changed like for like....

switched spur back on and heating fires up but goes off again after a few seconds...even weirder is the room stat has no electric goin to it now???

i never used the room stat before i changed it but presumed the wires were live all along???

coincidence i changed stat and now heating is foocked??? i think not

You should have live in, live out, neutral and earth(if needed)

You may have the lives back to front.

What stat is it?

nope deffo only one cable there...a 1.5 twin and earth

live neutral and earth...but not even getting a reading with a multimeter between live and earth

god i hate things sometimes


wish i would've checked if i had a supply there in the 1st place, i'm stoopid


ah well

Is there a reading between neutral and earth? May not be neutral.

no nothing there at all, even put a little volt stick by all cables and nothing!!!

when placed by plug socket starts beeping like crazy so i know its working!!

pardon my ignorance put where should the supply for the stat come from??

Something is either disconnected or you have a live missing

If a combi, the boiler, if a traditional system, usually the wiring centre/ch on output from programmer.
