I have a Pentair Spa Side (IS4) that is in my in-ground spa and connected to a Pentair IntelliTouch control panel. None of the 4 buttons work any more. There is a light that flashes when the heater is on. I had read a post with a similar issue who was able to set the Spa Side setting to OFF, waited, turned in ON and all worked fine. I don't seem to have that option with the IntelliTouch, but was wondering if someone knows how to do that?
