With this option you can select interval watering from 1 to 31 days.

1. Turn the dial to the Water Days position.
2. Press button until the cursor is flashing on the day 7.
3. With the cursor flashing on day 7, press the button once more until the two calendars and a flashing 1 appear in the display. Interval watering schedule appears on the display.
4. Press the or button to select the number of days between watering days (1 to 31). This is called the interval.

The controller will water the selected program at the next Start Time and will then water at the interval programmed.

Example: You program the controller at 8:00 am for the following:

Program A
Start Time 10:00 am
Interval = 5 days

The controller will run on today at 10:00 am and water program A. Then, the controller will wait 5 days and water again at 10:00 am and so on.

Had you programmed the controller at 11:00 am rather than at 8:00 am, the controller would have watered tomorrow at 10:00 am and then watered every 5 days after that at 10:00 am.
