To irrigate any station on an automated irrigation schedule, stations must be assigned to a program. Each program can be set with its own start time, water window length, and water day mode. A water window is determined by the start time and duration in which irrigation can take place. Each program can have its own water window, independent of other programs. Water windows can be set from a low of 1 hour to a high of 23 hours 59 minutes. The end time is automatically calculated, based on the start time and length of the water window that you set. 

Many times, shallow-rooted plant material and new landscapes are at risk of depleting their soil moisture before the next scheduled irrigation cycle; therefore, a second start time can also be set. This is useful for areas that are subject to extreme daytime temperatures and/or high winds, as well as for new landscapes.
