Help - Hive Thermostat Receiver Wiring

egg102530

Hi, spent about 6hrs trying to find the answer to this today and would appreciate any help available.

I am in the process of replacing my old clock timer (AMT IMM24) which turns on/off my oil boiler with a hive single channel receiver.

I am not worried about the separately controlled water heater. Its simply the boiler coming on/off I am trying to control.

See attached photo which summarises current setup / planned setup. Also below:

AMT IMM24 Terminals
3 - Neutral (currently both blue wires are connected)
2 - Live In
1 - Live Out (this goes to the boiler)
Earth is tied off separately at both ends.

I had planned on doing:
AMT 3 > Hive N (not sure if putting both blues in is an issue)
AMT 2 > Hive L
AMT 1 > Hive 3 (Heating on (NO) )

My main question is what to do with the extra blue cable:
1. Connect both to Hive N?
2. Connect the thinner 1 one only to Hive N?
2. Keep both connected but separately to the hive.

Any help would be greatly appreciated, its driving me nuts all day.

Thanks
Dave

You might be better moving your question to the Electrical forum where more will understand it.

I’d imagjne that you’ll need to link live to common.
