I'm having trouble programming my Pentair IntelliTouch Pool Controller (Part 520138 ?). The setting of the start/stop times are driving me bananas. Setting start and stop times are quite easy. My problem is, it doesn't follow my instructions for about 24 hours. Normally, I have the pump start at 10 AM. Because of a servicing need, I wanted to change the start time to 2 PM. I made my programming change four or five hours before the normal start time of 10 AM. At 10 AM the pump did not start, I was happy. Then at around 12 noon, the pump DID start even though I had programmed it to start at 2 PM. I read the manual three times, I think I understand a little bit about the "Egg Timer". I don't know if that's interfering with it. I don't know why it won't do what I want it to do. Based on past experience with this controller, only after about 24 hours will it obey my programming. How do I get it to obey my programming right away?
