Another Nest Install...

[Timitfc]

Hi Guys,

I’m pretty confident on the Nest install (thanks to @stem posts on here and their manual) - however my Worcester 35CDI ii currently has a programmer built in. Do I just leave this set to On and the Nest just sent sends back when to fire the boiler?

Thanks in advanced.

The programmer should be set permanently 'on' 24/7 the Nest will replace the room thermostat and take care of both the time and temperature control.

Great thanks. That’s what I guessed but would double check!

Thanks for your help through all the other messages!
