Hello @Rich, there is no way to program delays in between each station. In order to program the timer for indexing valves, you will need to wire jumpers from station 1 to station 3, and from station 3 to station 5. You will program 1, 3, and 5 to run for your duration, and stations 2, 4, and 6 will have your delay minutes. Then you will program 2 start times. The first start time will water your first 3 zones, the 2nd start time will water your last 3 zones.
