Fix old Pentair Compool LX220 solar heater panel

[BoneDr210]

I had Aquatherm solar panels installed yesterday - day 2 and love feeling the warm water coming through the jets. Thank you for all the help with deciding on the panels!

There is a Pentair Compool Lx220 controller on the wall. There is power going to it but doesn't seem to be working in "auto mode". Actuator turns the valve on and off when the panel switch is on or off, just doesn't kick "on" under auto when there is an obvious temperature difference and the desire temp is cranked all the way up.

The installer offered to install a new panel but I asked him to hold off as I am thinking of upgrading to intellicenter. He put in new temperature sensors, so it's not that. He said it's probably something on the panel/motherboard that isn't working. Even when the solar and pool temp sensors weren't connected, there was no "red light" next to the "water sensor service reqd" or the "solar sensor service reqd", if that means anything...

Any easy fixes?

That is an excellent solar control that is still available at some places. You likely need a new board, that is also listed as available some places.
A better option is the Hayward GL-235 that is less expensive than the Pentair/Compool board and works virtually the same as the LX220. About $300.00 on Amazon. Easy install and will use your existing temp sensors and valve actuator. It may be labeled Goldline as well, they originally made them before Hayward bought the company and it is still on some equipment and ads.
