NEST and Alpha 280p connections

coopersim · 20 Jun 2014

Hi,

I'm after a bit of help with wiring a nest stat to an Alpha 280p boiler, the terminals on the boiler are as such:

I'm struggling with understanding which of these are demand and satisified and the corresponding terminals on the nest it has to connect to.

Thanks

Terminal 2 is live out from boiler to ur timer/stat and the switched live goes back into number 1. Hence when terminal 1 is live your boiler will fire.

Doesn't really matter which way round they go in the nest though
