edited- I misread my instuctions for the new programmer!
I thought I should be removing the live link to the 'off' switch terminals that were existing on the backplate, but it said keep any links.
but I'm still confused as to why i shouild need a live link to both off switches?
Why would you ever need a live feed to switch something off in the 1st place?? (I understand electrics too (physics teacher!) but don't get this one...)
Anyone enlighten me? Ta.
