Hi I have a wireless thermostat to my boiler and I think the receiver has stopped working as the transmitter seems fine.

I don’t seem to have a manual override for the CH on the boiler so wondered can I simply connect the wires together which go into the boiler to test if it’s the boiler or the receiver?

Here’s inside the boiler. Can I just bridge those left 2 together to turn the CH on?



Or will I blow myself up flames

RTFM.
The manual for most boilers can be found online.
It will show what connections start the boiler.

Thanks but you’re missing my question. I know these are the connectors. What I’m asking is will just putting a wire between them bridge it and turn the boiler on. What sort of voltage is going through a thermostat or literally is it just a trigger?

Yes you could put a lucky link in. Voltage may be 240VAC, so take care..

The answer will be in the manual.
If these connections were not used before, they may be over-ridden by the opentherm or whatever.

Open up the stat and if it's just a 2 wire job bridge them there.
Care must be taken though.as there could be 240v on them.
I would guess yes for brigding those 2 you showed a picture of but would ideally like to see the boiler diagram to confirm.

There will most likely be mains voltage - 240v - so beware
