Operating the Sprinkler Timer

After programming the timer, you will

normally set it to SYSTEM ON mode to operate

all programs automatically. You can also

manually run one or more programs, or

manually run a single station or several

stations.

In addition, you can adjust for changes in the

weather or time of year with the Seasonal

Adjust feature to increase or decrease the

run time of all programs by a selected

percentage (in 10% increments). You may

also wish to run a test program to make sure

all sprinklers in the system operate properly.

System Off

1. To turn the timer off and suspend all

watering, turn the Programming Dial to

SYSTEM OFF.

2. In the SYSTEM OFF position, the LCD

displays OFF. The timer remembers the

current time and date and retains all

programming, but no watering occurs.

You may wish to turn the timer OFF during

a rainy period, or for any day(s) when you

do not want watering programs to run as

scheduled.
