I have a question about programming my VF pump. I have a 13,000 gallon pool, and I programmed the pump to run 24/7 and to turn the pool over 1x/day.
Doing the math, (13,000/1440 minutes in a day), I would expect the pump to run at about 9 GPM. However, on a clean filter (2 PSI) it runs at 1035 RPM and 15 GPM (about 130 watts). Admittedly, that's pretty darn cheap, maybe 35 cents per day.
My question is why does the pump have a lower limit of 15 GPM (@1035 RPM)? Shouldn't it drop down to 9 GPM (and lower RPMs) to accommodate the requested 1 turnover in 24 hours, rather than the 1.7 turnovers I'm actually getting?
Thank you,
Jon
