Replacing Honeywell HCW 80 thermostat and HC60NG receiver with a HIVE system

[owena50]

Hi there,
I've recently bought a new HIVE active heating system to replace the Honeywell HCW 80 thermostat and HC60NG receiver for the Viessman combi boiler in my flat.
I'm trying to understand where the wires going into the HC60NG receiver unit would go into the HIVE receiver unit.
I've attached a photo of the wiring in the HC60NG unit and I'm hoping someone can help advise which wire gets connected to which connector in the schematic I've attached of the HIVE unit.
As there's only a handful of wires I'd rather not have to get a plumber or electrician in but I also don't want to damage the HIVE receiver or boiler by wiring it wrong!
Any advice gratefully received!
Thanks.

Precursor warning - if you definitely got a Hive single channel then should be ok to proceed:

L - Brown to L
N - Blue to N
Com - possibly black to com terminal 1
Switch live - possibly grey to NO heating on, terminal 3

Being a switch I’ve been told either way around, doesn’t matter

Thanks. It's definitely the single channel for a combi boiler. Appreciate your help!
