Good morning all I hope you are all well? I am after a bit of advice please, I am looking to fit a Drayton LWC1 wiring centre into my boiler circuit as the wiring is incorrect, someone has linked the Neutral and HW off wires in the programmer circuit for some reason. Looking at the wiring diagram supplied with the Drayton LWC1 wiring centre it says to put the boiler S/L to location 12. My boiler is a conventional Baxi eco blue 30 ERP and it only has a Live, Neutral and earth supply to it, so I was wondering if I would need to supply a switch live feed to make the system operate? Any advice would be greatly appreciated. Many thanks.
