I have a Pentair iS4 spa-side remote. A couple of years ago, I started having troubles with the buttons not working properly. I may have to push them several times to get them to work. I then went down to only one button working at all. Now I can't get any of them to work. The little thing costs $175, so I would prefer not to replace it. Could it be a programming problem with my i5? Any help at all? Thanks
