Hello, Still very new, and learning, but getting lost with something. on a b&w screen, with logic, I am able to control some lights etc.. and, i've also managed to control my blinds, with some crude logic. i'm slowly getting around to controlling my underfloor heating and socket outlets, but I'm having some troubles... my problem is, from a DLT i can set up a secondary application to switch a relay output on/off. If I then try to set up a button on the screen to switch off the same/any relay, it doesnt work? The only difference i can see is that I've put all my underfloor heating and socket outlets into the 'power' application? Any susggestions? TIA, Aaron
