Hello, I am a bit of a novice but a friend who has CBus installed by the same person as mine asked me to have a look at his ... The previous installer has gone awol so we are left with no one that has any clue to how he set it up. Anyway I went and had a look and cannot find a CNI anywhere in it... I though that you needed this to run it but might be wrong and only need it to communicate with the cbus. So in saying that what are my options .... he would like to get Wiser like I have on mine so would this kill two birds by installing one of these... I installed my own wiser with a few issues initially with connecting but now it works fine and I can do my programming via the wireless now .. Also I had a look at his touch screen and it is a 5000CT which I am usure of how to connect to program Cheers, Travis.
