Jandy RS All Button

Having some strange behavior with my Indoor controller. After 9:30 PM the last wo days (doesn't start at the same time), I'll notice the Pump/Spa lights come on, go off, flicker, come back on, sometimes the spa comes completely on, then shuts off. I went to the box outside, and I hear the relays clicking and my automatic Jandy valves that control flow to/from the pool/spa are rotating back and forth randomly. If I put the box in Service mode, no problem. I put it back in "Auto" and the valves start randomly rotating again. If I leave the system in Service, the next morning I can put it Auto and everything is fine. Pumps come on at the programmed time, and shut off. But then, again after 9:30, the relays start clicking and things go nutty. I've "reset" the indoor and outdoor control boxes, no change. I've checked all programs and NOTHING is set to come on after 5:00.

Any ideas?
