Hi! Yes I was also very wondering, as I looked up the compatibility list for the opener, I noticed that TCS is removed from the list!? I have started a new thread, where I asked why! Because before a few months, I got a new intercom - the TCL ISW 3030, and to this time TCL was present in the list with many models, and I have literally a TCS fully working with the opener here since months, so I really don’t understand why they removed TCL!? I hope we get a few answers!? But you can still set it up as generic bus, what should also work without issues, - when I remember right, I also have set it up as generic bus! Do you need my wiring scheme, what I use!?
