Replacing Potterton EP3002 with Nest Heat Link

[andusbeckus]

Hi, I have purchased the Nest learning thermostat and need to replace my current controller with the nest heat link.

I could do with a little help as to make sure I get this right the first time.

I’m normally ok with this sort of thing but I’ll be honest this one has me a little confused.

Pictures are below with nest wiring diagram.

On the EP the link between Live & 5 can be done away with, 3 is HW on, 4 is CH on, all the others seem to be Neutrals (blue) on the left & Live (brown & red) on the right.

Thanks, so 3 can got to 6 on the nest and 4 can go to 3 on the nest is that right?

Will be a squeeze to get it all the rest in the Nest so may be better putting it in a connector and mounting the Nest next to where the old controller is.
