I'm trying to replace two old time delay switched and am confused as the where to wire the 4 cables in to the new switch, on the old master there is 3 red - Supply, Live and X and one yellow wire "Y"
The new switch only has 1 in and 1 out,
Could someone please advise as to where to put each cable, the second is a simple swap as it only has one red one yellow.
Regards
Martin
