I have an original controller that came with the pool about 15 years ago. It was built by Blue Haven and the controller says BH6100 which I believe is the same as Aqualink RS8. Last night the controller was dead, I tried to reset and looked at the wiring on the controller side. It looks ok. I can go to the main panel and operate the filter by putting into service mode. How can I troubleshoot this? Does anyone know the voltage that should be coming in via black/red wire? Should I buy a used controller or upgrade? I don't know my version since I can't bring up the controller menu. My pool guy told me to contact Blue Haven which I think would cost me an arm and a leg. Any help is greatly appreciated.
