A common reason for a controller to repeat a cycle is too many programmed start times. Only one start time per active program is required, a second start time will cycle the program an additional time.
NOTE: In the Start Times dial position, the numbers 1-4 do not represent stations. The numbers represent the program start times. Each program can start up to 4 times on the set days to water. One start time will activate all stations sequentially in that program. If you want the stations to operate one time in sequential order and then not repeat, set start times 2, 3, and 4 to OFF. Multiple start times in a program can be used for separate morning, afternoon, or evening watering cycles.
Individual stations are assigned to a program (A,B,C). Each program requires only one start time to initiate a watering sequence of all the stations assigned to that program. Start times are assigned to programs, not stations. The controller will operate the stations in numerical order. When a station has completed its watering time, the controller will switch to the next station in that program automatically.
Example: Program A has six stations (1-6) assigned to it and the program has one start time at 10:15 AM. At 10:15 AM, station 1 will water, followed by station 2, then station 3, and so on until all six stations have watered.
If you find your controller has an additional start time that is causing a program to repeat, the start time will need to be turned to OFF.
