The pseudo-programming effectively states, if it's daytime, and a motion sensor is on, allow the courtyard fountain to run, else, don't waste the electricity because either it's dark outside or no one is around to enjoy seeing it. This has worked well for a year. Now, it has stopped. To test the problem, I created a new program, simply stating if it's Sunrise to Sunset, to turn on a light, and that doesn't work either. The time shown on ISY is correct as are the sunsrise / sunset times at the top of the screen. The first question is, has something expired (some software that must be purchased)? Second question is, any ideas? Thank you everyone.
