I have a Pentair intelliflow pump and also have it set to run 24 hours per day at a low speed (750 RPM) that keeps the SWG happy. When the rooftop solar system decides that it is worthwhile turning on, it commands the pump to a higher speed, currently set to about 2300 RPM and then it movies the valve allowing water to go up to the roof. (Without speeding up first, there would not be enough pressure ot get the water up there and still satisfy the SWG). In the summertime, the water gets to between 90 and 95 degreees F. At night it goes down to the middle 80s.
My question is, where do I set the SWG controller percentage control? The controller automatically adjusts for temperature, so it fluctuates up and down every day, but I am afraid with it running 24hrs/day it will be on a lot more than is really necessary. So I figure I can compensate for the 24 hr operation by decreasing the percentage factor. And is the percentage the controller displays (Autopilot Digital Nano) also for the "current" temperature?
(The reason for wanting the pump on 24 hours per day is that the "freeze protection" feature of the solar heater can come on in the middle of the night to protect the panels from freezing, and it needs the pump to be running so it can command it to high-speed.)
My water test kit, the kind with numbered chemicals and a plastic test tube. is awfully hard to read precisely for Chlorine levels, since all you get is various shades of yellow.
