Thanks for the quick reply! My problem with changing the wiring is that I spent more than a day running the wires neatly with sleeving etc. and would prefer not to rip it all out unless I really have to. I guess I was too confident of success having taken advice from sites and forums that my setup would work. Half of it - the home and -- limits does work (!) so I'm hoping to get some guidance on either the inputs screen or maybe from someone who knows the Uniport BoB.
Cheers, Andy
