Hive single channel install

[Jon Smith1]

Hello - I asked a friend to install a Hive receiver for me, after they thought it was finished (paired in the app) they left.

It was never tested and now when testing the receiver is working but the boiler isn't kicking in

This is how the wiring has been left and it looks nothing like the Hive install guide - Any advice ? I get I might have to bite the bullet and get an electrician but the guide makes it look simple

Note wall like that for years.

I don't suppose you have a photo of what was connected there before?

That is definitely not the standard wiring for a single channel Hive install.

Do you know where the cables pictured here go to?

...I think you need to sack your friend!

Never got one

Annoyed I never got the photo before so I can't put the old stat on, I can't find a guide that has colours that match this either

I'm sorry.

I'm afraid it will be a case of tracing the cables back - one may connect to a fused connection unit, the other to the boiler?
...and you mention an old stat - did this replace the old stat, or a controller?

Sorry should say programmer, I was told to leave the old danfoss above it and leave it set to 30 degrees.

Ok good, that's progress! Can you show us the wiring behind the Danfoss?

I can't see any screws on it, it looks quite old, 100% no screws on top, bottom or side

Can we just check what boiler you have?

Behind the Hive, can you differentiate the 3 core and earth cable that doesn't have the grey connected?
This appears to be the superfluous cable to the Danfoss, the black and brown wires to this can also be disconnected - and the cable removed if you wish - it should be simple, if you can take the cover off of the trunking.

Ok, if you don't want to mess around with any more wiring, and you definitely have a single channel Hive.
Simply move the link wire connected between L and 2, to L and 1.
It may seem straightforward now, but we needed to check that nothing silly would happen!

...and the connection to the earth terminal could be improved, while you're at it
