OK you need a single channel hive you will see a red link on the pcb between terminals 3&4, you need to connect these to 1&3 on the hive , run an L&N to the hive and that is it , remove the plug from the VRT and you are good to go, do not make any links that you may see in other posts

That sounds nice an easy, but can you tell me which is the VRT plug ?

Vrt plug is the front panel wth the grey button and green light. Iirc this can be left in situ, but will justboight up red. You can purchase a blanking plate for it. Removal of your boiler casing on this model requires safety checks afterwards, to ensure the flue isn’t compromised.

So does the front panel just pull out to disconnect it. ?

Sort of, there’s a small slot on the top, a slotted screwdriver will fit, however do not leave it exposed as there’s pins behind which supply voltage.
