So if you look at the picture, the upper box is a 12 zone controller and the bottom a 4 zone. Should I get a 16 station controller to replace the two? They’re very outdated and no matter what I do, it keeps going through all 3 programs when I just want it to go through program A. The sprinklers turn on 3 times which I keep trying to undo. I just need it to run through program A once. I’ve got a large property but the system works fine. I’d just like something easier to use that I can program with an app. Any suggestions? I’m not sure what to do with the conduit that contains 12 stations, most of which are in the front yard.
