My Intelliflo's clock resets to midnight if the power is disabled for more than a few seconds.
Pentair customer service confirmed it should retain the time for 96 hours, and stated that if it wasn't, something was wrong with "the capacitor that holds the time." The only thing that could fix this is "replacing the drive," which they didn't recommend because "it's as expensive as the whole pump."
They couldn't tell me if the capacitor was field replaceable (I assumed there was a watch battery on the board--apparently not.)
Has anyone else experience this or found a solution (short of replacing the whole pump)?
