Aqualink RS4 - Phantom cleaner program

I have an aqualink rs4 controller on my pool. I think it was installed in 1998, so fairly old - 6522 REV GG. For some strange reason my clean comes on at around 5PM every day and runs for 2 hours even though there is no program set and the light on the cleaner button on the remote is not on. I can turn on the cleaner and turn it off and it stops the cleaner. If not, the cleaner will continue to run even after the main pool pump goes off at 6PM because the crontroller doesn’t seem to know it is on. I have cleared the existing programs and re-programmed, still does it. Any suggestions???
