I've got my Nest thermostat hooked up to my Vaillant TurboMax boiler but I'm not sure what I should set the C/H boiler value to? It has a dial from 1-10 and I usually have it around 7. Does it matter what it is set to?
Cheers
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!
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
