Bingo! Thanks for your help - all working!! Now to rebuild the cupboards ☹️

I’ve dismantled a cupboard to get to this... There is a grey that is not wired in (folded behind black in pics). It is in grey trunking as is the case at the sensor end. I am thinking to connect in with the other grey on the lhs which is connecting through to blue/neutral on rhs. Make sense...

No. I tested with a meter but no circuit. otherwise don’t know how to find out unless I can find other end at pump or boiler .

Grey is not N unfortunately. Is this likely to be something I can wire in? Would it be at the pump or boiler or ? Thanks

This one is for underfloor heating. I’m looking to replace a honeywell CM907. There is a grey wire not connected that I’m hoping will provide power? The new controller I have for this is slightly different (should I have bought the same as above?) Really grateful for your help Thanks again

Thanks for the replies. That is how I’ve wired it - with a bit more testing it IS working but has a 3 min delay on powering up. I guess that’s an energy efficiency thing. I have another to do now that I’m not sure about though so will be posting again if you’re able to help...

Hi I’ve bought a Smart thermostat to replace my existing. I thought I had the wiring sorted but it’s not working. Any advice gratefully received. Pictures of new and old attached. Thanks!
