Sorry, me again.
Just for confirmation/a second opinion, this is next to the boiler. Looks like the thin black wire not connected is the one that terminates behind the tp5000. I just need to hook that up to the middle connector on the block (with the mains turned off as this isn't on its own...
No such luck, I'll see if I can find where the wires come out to the boiler, obviously being careful of opening up something I shouldn't as per your previous post about a gas safe engineer
I'm using a multimeter, I had the other terminal against the mounting bracket of a nearby radiator although that wasn't earthed itself so I'll try again with a light switch and report back!
Yes, there is a blue sleeved wire behind the wall along with an earth and your comment about the brown sleeve hogged my memory of changing multiple light fixtures and they all had these grey wires with brown sleeves for the live, electrician the wired the house must not have wanted to pay extra...
Thanks for the reply. So to clarify what I'd want to have done by a gas safe engineer, I'd need the BDR91 connecting to the boiler somewhere, probably in the cupboard container the boiler, and the Tp5000 will become defunct as there is no replacement for it in the evohome system?
I currently have a danfoss tp5000 at the bottom of three floors that controls the entire house. It's terribly inefficient and leaves most rooms freezing whilst one or 2 are unbearably hot so in looking at a smart TRV system and settled in the evohome.
What is currently connected is the danfoss...
