Help installing Hive receiver and thermostats

[balmain-by]

Hello All.

I have an Ideal HE18 boiler with a Honeywell ST9400C controller and two Honeywell T6360B thermostats.

My understanding is that I can do a direct replacement of the ST9400C with the Hive Receiver and then disconnect the two stats BUT link out two wires to remove the open circuit so that the Hive stats can take control.

Firstly, is this the approach to take?
Secondly, which wires need to be linked on the stats? My cables are Brown in 1, Black in 2 and Grey in 3. The metal pattress box is also earthed.

All pointers greatly appreciated.

Paul

No, each old Honeywell thermostat will be replaced by a Hive thermostat.

I get you now

1 and 3 2 should be neutral

But really you should alter your wiring in the wiring centre
