My RJ-60+ is showing the subject message. The guys at Circupool were very quick to try and walk me through a troubleshooting sequence. They're now sending me a 'RJ60N PCB Adaptor' that goes between the control board and the plug for the cell. I installed the unit in April and haven't had to do more than adjust the output since. I brag on it every weekend. I get the part Friday...wish me luck. Has anyone else been down this road?
