Honeywell receiver (R4H91) to Hive Receiver (single channel)

[dxg169]

Hi, I'm replacing an existing Honeywell receiver (R4H91) on my combi boiler with a Hive (single channel) and am confused with the existing wiring in the Honeywell. See images below, 1st image of the current receiver wiring, 2nd image of the wider system wiring in case this is helpful.

I'm a little confused as the earth wire terminal in the Honeywell isn't being used, and the earthwire seems to be going into the switch.

Can someone please confirm which terminals in the Hive receiver I shoud be moving the wires to?

Thanks!

Brown wire (from the flex) to L terminal on hive reciever.
Blue wire to N terminal on the hive reciever.
Then you create a link from L to Common on the hive.
Your "earth wire" goes to terminal 3 (Heating on).

Make sure you add sleeving to the earth wire as it will be live.

It's because 3 core cable has been used instead of 4 core. It doesn't matter if you sleeve the earth wire.
