New to group. AutoPilot Total Control. Have had many years. Came back after the summer and the system had gone offline because of the flow error. However, the trisensor and switch works perfectly, the cable rings out to the communications board in the Autopilot. I did remove and clean the circuit boards because there was some salt and flux that seemed to be a bridge on some of the circuits but the boards are perfectly clean now and appear in good shape.
I have tried to change the setup from Total Control without Flow Sensor in the Installer Menu but the unit resets then continues to display the flow error. This tells me a circuit board might be at fault because Tech Support suggested removing the flow sensor from the options would allow the unit to run. But, it does not.It seems silly to spend hundreds of dollars for a board where the only problem might be a small relay or diode or other discrete component.
I'd sure like to try to narrow down the location or problem before spending a lot of money on boards. Does anyone have any thought on where the location of the problem might be with these symptoms? Comments are really appreciated. Again, the switch is OK and the resistance at the communications board rings out to 1 ohm verified when the pump turns on. The board is 2006 vintage and the Total Control system is now completely stopped with no acid and no cell activity because of this error.
