I've been out of the trade for 3 years now and I'm having a brain fade in my old years. I'm installing a Drayton digistat SCR (acually a B.G. WR1 if I'm honest) and wireless drayton stat in to my vaillant 618 system boiler on a S-plan system at home (replacing ancient sunvic wired stat)but for the life of me I can't think of the basics. The diagram for the SCR says to pick up the switched live at the wiring centre and the neutral of the heating motorised valve. Pretty straight forward right? Not for my tattered brain. What switch live? Is it CH On from the timer? Also do I just tee in to the neutral from the motorised valve? I must admit most of my jobs concerning digistats were on Combis. No problem there anyway but the zoned one is leaving me stuck. Cheers in advance
Dear Moderators, I'm not sure if it's okay to say this so please delete this bit if it's not.
As I've retired I've now have a lot of motorised heads and bodies as well as syncron motors, circuit board, pumps, old hot water heat exchangers that can be cleaned up (used on dirty systems before. Old company didn't want to power flush so just used to clean water H/E and put it back. Didn't like to do that but I wasn't the boss. Also a MagnaCleanse system cleaner (the machine not the little the little things you install to keep the system magnatite free). Only used twice. If anyone is interested let me know in a reply post to this. I'm in Southgate, North London.
