Water timer on Turtle Creek Circle

First things first.  After turning the dial two notches to the left, the clock may take a few moments before it displays the percentage of water it will deliver.  I have it currently set at 70% (February) with three watering times daily.  Only one station waters almost all of the back yard, with a duration of ten minutes.

 In June July and August, if the plants look a bit dry, I suggest increasing the % of water delivered adjusting as seen in Fig 2.
