Hive receiver is not switching the boiler off

MAKE:ideal boiler 30+ combi
Hi, im fitting this hive into this combi boiler, ive done all the wiring as I usually do but for some reason the heating just keeps going up and up and not switching off after it exceeds the heat in the thermostat. Ive attached the photos if the wiring. Please help

If you turn the Hive up to maximum, or if the Hive is removed from the backplate, does the heating turn off?

the heating only turns on when I put the receiver back on the plate. If it’s not on the boiler sits at zero

Try moving the brown wire from 2 to 3.
And thanks for the answer, there appears to be unseen connections between the boiler and the Hive, so I wanted to make sure.

Doesn’t turn on when I move it over

Do you know where these connections are made? Does the cable to the Hive come from the FCU, are the connections made in there?
The cable to the boiler is a 5 core flex and the wiring to the Hive appears to be a 3 core + earth.

The terminal connecting the short link wire between L and 1 also appears to be biting into the insulation, rather than the wire.
...and a really silly question - it's happened before - you do have the single channel Hive?

And I should clarify - when you moved the brown wire to 3, what doesn't turn on?
If the Hive itself doesn't turn on, you need the black wire in 3 and the brown wire in L.

I think it’s wired wrong. As per @RandomGrinch you need to ascertain where this wiring goes, do the colours follow suit inside the boiler? Make sure you safety check the boiler afterwards after removing the cover.

It seems a 5 core cable leaves the boiler the colours are hard to make out, but does not seem to be same cable as shown in the other picture as it has swapped from flex to three and earth, so there must be a junction box some where.
