Just installed the Intelliflo VS-AU. I am really glad I waited because I have no use for SVRS but I certainly want the controller!
My question is what kind of schedule should I set for the pump. I plan on running two speeds - a high speed to power the suction cleaner, and a low speed for circulation. I was going to target 1.5x turn per day.
When I use the watts table spreadsheet, I see that my flow rate is 20 from 400 - 1200 rpm. Is this normal? If yes, what's the advantage of setting 1200 rpm vs. 400 rpm when I get the same flow rate but I use half the energy at 400 rpm?
My next question is the DE filter. When the speed / flow rate is low, the pressure at the filter is low. Am I still filtering the water even at 20 gpm and very low pressure (psi gauge reads like 3-5 psi)?
