Thank you Chris for your very swift reply.
Yes my MEE switch has two sides and nine wires, info noted re the resistors.
One final possibly dumb question if you don't mind.
My A100 has been messed with by previous owners and I am trying to get it wired correctly and safely.
I am UK based. Regarding AC in, all the info I can find seems to suggest that Neutral (our blue) or AC common should be grey or white and that Live (our brown) or AC hot should be blue or black or red.
On the A100 it seems to be the other way round, Grey appears to be live or hot and neutral is blue.
Does it matter? or am I being fussy.
Thanks again
Robin
