WB Greenstar 30i ErP & Hive

[grahammm]

Hi all,

Another hive install question!

So we have a WB Greenstar 30i ErP and currently a Honeywell thermostat.

The current boiler has a L, N, E supply. It then has two wires which seems to go to 1 and 3 on the honeywell.

Is anyone able to give a simple list of which connections need connecting.

I presume the following but may well be wrong!

230v N out on boiler to N on hive
230v L out on boiler to L on hive
not sure about 1 (Common)
Presumably left empty - 2 (Heating off - NC)
LR on boiler to 3 (Heating on - NO) on hive

Yes, not far off. Common on Hive will be the number 1 from Honeywell. All others look ok, yes 2 left empty.
