Nest Learning Thermostat Installation

[UkDean]

Does anybody know how to wire up Nest Thermostat to a valliant eco tec pro 28 combi boiler, i have heard contradicting ways to install and not to follow the installation guide.

The setup does not include a room stat, cylinder stat, zone valves etc 

Any help will be much appreciated.

Kind Regards,

Follow the instructions of the Nest and the boiler, its not very complicated

Yes, as above, just follow the Nest instructions. Don't know what the contradicting information is so can't comment, but there is nothing wrong with just doing it the way it says to do it in the book.

The heating system works through the nest, the combi boiler needs a permanent feed for hot water, we dont have a permanent feed now as we are going through the nest control. Any ideas?

Put a permanent feed to the boiler from the nest controls, :C

you removed the boiler feed and used it to power the nest which controls the boiler that now doesnt have power !!!!

the instructions do not tell you to do that.

I think the clue is in the question. The boiler doesn't have a permanent feed so maybe give it a permanent feed?
