How to Set START DELAY Function
You can easily delay the start time of the current watering program by pushing the
“START DELAY” button. After the watering program is set, push the “START
DELAY” button until the indicator is “Red”. Once the indicator is red, press the
button one time for each hour, up to 12hours max. Every time the button is pressed,
the indicator will flash “Green”. For example, if you want to delay the program for 5
hours, please press the button 5 times (the indicator light will flash green 5 times as
well). Once the red indicator light is off, the start time setting is complete.
*Please complete the programming process within ONE minute.
*After each programming change, press the “START
DELAY
” button and when the
indicator turns red; the start time program has been reset.
