I have the temperature set for 86 and what typically happens is the pool cools overnight, the pump comes on about 11 am and the controller diverts the water to the panels. Sometime later in the afternoon the temperature reaches the set point and the valve is turned so no water can go up to the panels. I was in the pool about 4 pm and decided to turn the temp up. The water that came out of the returns was scalding hot. It had been sitting up in the panels for a few hours - that can't be good for the panels.
My solar panels are plumbed correctly with a valve to either divert water to them, or bypass them. The return has a check valve so water can't go into the panels when the valve is in bypass mode. The problem is that the pump pressure keeps the check valve closed and so the panels stay full. Once the pump shuts off, the panels drain completely. What am I doing wrong?
