The behavior you describe is not what I am seeing. Here is a sample program with three stations starting at 2:00, 2:01 and 2:!0. If they are really going to run in sequence then they should be queued up after on another and run from 2:00 a.m. on. However the preview only shows the P1 program running. I haven’t tried testing the actual sprinkler control but if it’s the same as the preview then stations 2 and 3 will not come on.
