I did a quick search here on the forum and didn't find anything related to this question.
I had one of my AUX buttons configured for a "Group" function in order to control a few things under one button. Specifically, I was controlling the pool Spill-Over function with it. Anyway, I noticed that it wasn't working one day and when I went in to the config I noticed that I don't have the "Group" function as an option anymore. I just have Manual On/Off, Super Chlorinate, Timer, and CountDn.
I don't get into the config too often (thankfully) but I don't seem to recall it being this difficult to program the "Group" function. I'm sure it's probably something simple and I'm just missing it. I looked through the manual and it talks about it being there and I followed all of the steps but still no "Group" function for any AUX (or any other) position. Hopefully someone out here knows the quick answer to my screwup.
