Heating worked fine, I believe the old thermostat (TP400) used the brown wire into the com port and the black wire into N/O (I wish I'd taken a photo!), I believe the black is the switched live as said above by RandomGrinch. The old thermostat used batteries though. I've also realised I've got...

Its awful! I could move the grey wire to a neutral, but right now I'm not 100% sure where the other end of that wire is as on the top floor both the brown and grey wires carry a current and the black wire is dead. The cable behind the two thermostats is 3 core and earth where as all of the...

Hi all, I've been let down a couple of times so I knocked all the power off while it was light and had another look at this, I've traced the wires as follows however it is very confusing as all the colours are mix matched. Apologies for lack of terminology, I'm not an expert, I just like...

Turns out I do have a grey wire behind the thermostat. I’ve had it off to try and neaten the area up and found it. I don’t believe it’s a neutral though. I had a go at working out where it leads but it’s not the boiler and it isn’t the junction box as the wires are different.

I started by looking at the valves and seeing where they went and found this: The wires don’t match what’s behind the thermostat but if that is like that, I’ll need someone in anyway and they will likely be able to sort it much quicker and safer than I can.

Cheers for the replies, I think I'm going to get someone in. I looked at where the wires go into and it's just a load of wires crammed together into a cheap terminal connector block which is then rammed into a hole in the wall. That is a bit too much for me to take on and I'd like it done correctly!

Need a little help! I installed a Hive thermostat to control the ground and 1st floor (annoyingly they share a valve) and all went well, recently the thermostat display on the top floor has died and so I decided it was time to update it to a Hive, I can get it powered up but I can’t get it to...
