The problem with electronic systems like yours is that solutions are unit specific, not generic.

By that I mean, mechanical parts that do similar things tend to be similar, so solutions that work on one, often work on another. But, with electronics, you don't have parts, as much as you have programing and wiring -- which tend to be specific not only to that manufacturer, but even to that model.

I'm going to move your thread out where others can see it, but I'm not going to hold my breath, while you wait for an answer. If it were me, I would:

1. Collect that exact make, model, serial number and approx date of mfg;
2. Read the manual carefully - you can start here => http://www.zodiacpoolsystems.com/Sup...edge-Base.aspx
3. Search the web by model number;
4. Call Jandy customer service: (800) 822-7933; productsupport@zmp-zodiac.com

I would call last; you are most likely to be able to get out of Level 1 support, and up to Level 2 (where you're talking to someone who knows which end of the wrench to grab!) IF you've already eliminated the easy problems yourself.
