Good info as always Phil!
I want to add one more tip to Phil's troubleshooting procedure.
If you have full sun, jumper the PV output to the pump input
conductors and if the pump runs,
the controller is at fault. That's assuming that the float switch is
calling f
Just got a letter from Fat Spaniel Technologies.
If my legalese is up to snuff, it appears that they're liquidating the
company.

Ah yes, the dreaded F3.
Loss of communication between the Cu200 controller and the pump.
Grundfos has had this problem on and off for several years now and I
wish they would
correct it once and for all. We've had 9 systems with the F3 fault
and 8 were bad CU200
I believe the F3 error code was the known communication issue with the CU200
controller. Basically, it loses communication with the pump and so throws
the error code. I saw a bunch of CU200 controller issues in my previous
job; GF acknowledged they had a bad batch, and were pretty good about
swap
Gary,
I've had trouble with the rubber sticking to the helical rotor in a
couple Lorentz pumps. Both were off for several months during the
winter because the cattle are gone. Seems like your Grundfos pump
situation is different.

Kent,
It would only be off if the tanks were full. Why?

Gary,
Any chance that the pumping system is off during the winter?

All controllers were displaying F3 failures, there was voltage at the well
head. Only one replaced so far and seems to work fine.
