With the iGrow1400 you can Program Cycle Irrigation and have your Irrigation Valves Turn on and off within a specific time window.
To program simply hit Enter/Menu -> Program Equipment -> Hit Enter/Menu to highlight Output -> NEXT to scroll over to Equipment type field -> hit + till you display IRR then hit Back. Hit NEXT to highlight the MODE -> hit + till you highlight Cycle.
In the second screen you will set the time window with Start and End times. The start and end times can be fixed or they can be related to Sunrise or Sunset, if you like. You can cycle through the three options by pressing the + key when the cursor is over the at.
The Cycle Time is the combination of the On time and the Off time added together.
