I have a Glow-worm Ultracom 35cxi boilerand have bought a Google Nest 3rd generation stat.

I have attached an image of the current relay box installed.

Can anyone explain how to wire the Nest Heat Link to my boiler please?

Thanks in advance.

Would help if you showed the terminal descriptions for the nest

Thanks, please see attached.

I'm going to run the thermostat off the USB plug/wall socket.
