A common mistake many user make when programming their irrigation controller is trying to program a start time and stop time for each zone. There is no need to program a stop time for each zone. When programming the controller, enter the run time for each zone into a program and set the start for that program. The controller will automatically start the next zone once the run time has expired for the previous zone. If no time is enter for a specific zone, the controller will skip over it and water the next zone that has a programmed run time. For example: On program “A” you want zones 1,2, and 4 to water for 30 minutes each starting a 6:00 am in the morning. Set the start time for program “A” for 6:00 am and enter 30 minutes of run time for zones 1,2, and 4. The controller will start zone 1 at 6:00 am. At 6:30 am it will automatically start zone 2. At 7:00 am it will automatically start zone 4.
