I'm a little lost adjusting watering time on zones

Our gardener asked me (the home owner) to decrease the water on one zone (trees in front) and increase it on a second zone (trees in back). We’re in Phoenix, AZ where it’s hot. It looks to me like I need to go into advanced settings (both are scheduled to water in the evening as needed). Can someone make some simple recommendations as to what I should change in the settings? Front trees is mainly an Ironwood, rear are mainly citrus.

You should just be able to go into each schedule and adjust the watering duration for individual zones.



I guess I’m a little slow. Thanks - I thought the unit was adjusting itself
