I set the timer on the contol panel (Hour, Min, am/pm). It has 4 automated filtration cycles above and beyond the 24hr circ pump.
Sort of a deep filter cycle. I can adjust set points for when it does this and for how long. I noticed after a couple of days that when it goes through one of its cycles, it is not where I set it according to real time. When I check the panels time display, its way off.
OOPS... I looks like I'm gainig an hour every day not loosing.
