This is a long shot... almost worth not typing but you never know!

I've just bought a Honeywell T6 smart thermostat - sold as 'untested; spares or repair' and I can see why! The receiver doesn't have any terminal blocks to wire to as seen below:

I have managed to lash up some crocodile clipped wires to test it in a fashion that'd give an NICEIC inspector sleepless nights and whilst it confirms everything works it's not an ideal permanent solution.

I was wondering: does anyone happy to recognise the terminal blocks that Honeywell use from these views taken off the web:

I think they're known as 'pluggable' terminal blocks by virtue of the fact that they accept metal pins from the receiver lid that make contact as they insert when the lid is enclosed. They appear to be just clipped in.

If I can't find them it's not the end of the world - I can either lash something up or, if I'm not keeping it (this was part of the reason for taking a punt - I want to see how good/usable the kit is having been quite unimpressed by the Nest equivalent) I can always sell just the transmitter on and not be out of pocket.

Yes I very happy to see millions of the things, but none that look close
enough that I'd take a punt on ...

What's the pitch of the pins? Are there any markings on the body of the
connector? You could try going on Farnell and filter by pitch and
manufacturer to whittle it down.

If you are keeping it you could always desolder the connector and replace
with a matching plug and socket of the same pitch.

5mm pitch, and the pin diameter is 1mm so they're sounding 'standardised' to me?

Yes, I thought I could probably even solder wires directly to the pins (heatshrinked) and connect them to some Wagos. There a fair bit of room inside the backing plate once the terminal block holder is removed.

I'll keep looking in the hope I can find them. And that they're 80p for a pack of three.

Posting to close this one off: I got in touch with Honeywell to enquire about about obtaining replacement terminal blocks and, to be honest, wasn't expecting a reply about what is essentially a 'low level' repair issue. I was therefore pleasantly surprised when one of their technical support guys said he was heading into the office and would see what they've got. He found a spare backplate and popped it into the post for me - great service Honeywell!
