Well, I got it figured out. I was setting it before during the on time and just had to wait till it got to next cycle. Sure am disappointed that it won't control a two light fixture even with two cords for each light. I just got the low priced timers for the rest of my tanks and they do about the same thing. The coralife digital does provide lots of outlets though, but it should for the $. By the way, the marineland small timer works fine and the pins are easy to set.
