My Pentair iS4 (in service since 2007) has just started to NOT save the pool schedule setting but does save the cleaner schedule setting. I shut the power off to the whole thing and then restarted it. The pool schedule was wiped out (none). I re-entered it and this morning it was wiped out again, yet the booster pump for the cleaner was running. Not good. Any thoughts on a correction for this would be helpful. Thanks!
