Screenlogic app for iphone. In the pool section, at the bottom, there are four tiles indicating the heater settings.
Off Heater Solar Pref Solar Only
I have mine on Solar Only. However, it blinks red when the pool filter is running, in the middle of a hot day. That is of course the time that you would expect the solar to be active.
What does it mean when it's blinking? It may mean it's "running normally" or maybe it means there is a problem. I cannot find anything about it in the docs.
When I feel the solar plumbing pipes, I cannot tell for sure if water is flowing through them. The filter RPM is 1800, so I thought perhaps I needed to move it higher to get enough flow to the solar. However, after moving it to 2500, the Solar Only tile is still blinking and I cannot tell if water is running through the solar system.
How can I know for sure the solar is working?
