Our FAFCO Auto Pool Solar controller just starting beeping and displaying Error Code S2.
Before having the solar company come out, does anyone know what Error Code S2 is?

FWIW, I've been having pump problems recently, requiring me to frequently turn the breakers off and on. Don't know if the repeated On/Off would cause a problem or not.

I had to remove the internal fuse to shut of the controller.

Thanks
