Hi Guys, I need help installing Nest 3rd Gen Thermostat wiring using existing wiring.
Currently on Danfoss thermostat and nest installation guide is confusing. I believe our boiler system is in S plan.
Our Boiler is Worcester 28CDi RSF COMBI.
Our current Drayton thermostat switches on water heating automatically when hot woter required. And central heating works same way; if we require heating we switch on central heating.
So need help in wiring Nest 3rd Gen Heat link first & then thermostat ring on existing wired thermostat.
I thing to do this:
1. Ls is as you suspect a permanent live (Ls = Live Supply) This would go to the Heatlink L,
and also be linked to the 'Heating Common' 2
2. Ns is 'Neutral Supply' This would go to the Heatlink N
3. Lr is 'Live Return' this goes to Heatlink 3, "Heating Call for Heat"
4. Earth to earth as applicable
Dont know what to do with wire from Timer and Thermostat
