I have a Jandy PDA-4 remote and typically works great but sometimes the time and date will reset to some default setting. This is a problem because it means my pump won't turn on at the designated times. The odd thing is that all other settings remain saved properly. I have the 9V battery in the Aqualink control box, although I'd expect ALL the settings to reset if the battery was dead or missing.
Any ideas? I am going to reach out to Jandy support tomorrow as well.
