Installing Nest thermostat to Vaillant Turbomax 242

[allanmb]

I have a Vaillant Turbomax 242 combi boiler and just got myself a nest 3rd generation thermostat. There wasn't an existing thermostat so this was a fresh install. I used this post as a guide
https://www.diynot.com/diy/threads/installing-a-nest-to-a-vaillant-turbomax.425632/

I just wanted to make sure I have wired up the boiler correctly. Below is a photo before and after but to summarise I have used a 3 core and earth cable with
3) brown (live)
4) black (switched live)
5) grey (neutral)
E) yellow /green (earth)

And on the Nest heat link I have
N) Grey (neutral)
L) Brown (live)
3) Black (switched live)
And a Loop between L to 2
The earth is unconnected

Does that look correct?
Cheers

Earth should be connected to Nest's earth terminal. You've forgotten to include your photo, but your description looks OK

I was using the mobile and it didn't attach the photos. Here they are below.

I didn't notice an earth on the Nest, I'll open it up again and connect it!
