Salus ERT20TX Swap to Google Nest 2nd or 3rd Gen

[Dazza65]

Hi All,
This is my first post. I did search for the info, found some useful guides but not same type as mine. I would like to swop out the Salus for a Google Nest. 2nd or 3rd Generation. I've not purchased one yer as I wanted to check the wiring first. From what I have fouind on this forum, it should be failry straight forward.
I can post some photos later. Combi Boiler is an Intergas.

Thanks

It’s fine if that’s what you want and wiring should be straight forward. Probably best with Nest 3rd generation or Nest E - both support opentherm, which will be better for your boiler

Hi
Thanks for the reply. Here are photos of my Salus system and wiring. The other thing I'm unsure on is which wiring diagram to follow on the Gen3 nest.

Well, if you want to use opentherm, there’s a diagram for that.
