We’re trying to connect a nest generation 3 to our ideal boiler. At the moment it’s wired to a honey well R6660D receiver the connections inside are live and neutral. There’s one cable that goes to B and one to C . On our nest control box I can see where we connect live and neutral and I can see where i link live to terminal 2 but what I cannot understand is which cable goes into no 3 as I’ve got 2 cables left which come out of the Honeywell receiver one from B and one from C?
