PROGRAMMING THE CONTROLLER
Your ESP-Si controller is an electronic clock that controls when your sprinkler system turns on, and how
long the sprinklers run.
Programming is the process of telling the controller exactly when and how long you want to water. The
controller opens and closes the remote control valves according to the program you set.
Each program contains:
n
Watering days — the specific days of the week on which watering takes place (for example, Mon-
day, Wednesday, Friday), or the watering interval (for example, every third day).
n
Start time — the time of day that the program begins; this is the time that the first station in the pro-
gram begins watering; all other stations then follow in sequence.
n
Run time — the number of minutes that each station runs.
Default Program
The ESP-Si series controllers have a backup, or default , program that takes over if your program is lost
because of an extended power outage.
When the default program is running, all stations revert to Program A, with 10 minutes of run time per
station. The default starting time is 8:00 AM.
The default program will water every day if the Schedule Slide Switch is set to “Custom.”
If the Schedule Slide Switch is set to one of the fixed intervals, the default program will run every two,
three, or five days, depending on where the switch is set. The Program A default settings will be in op-
eration until you enter your desired settings for Program A. As you enter your settings in Program A, the
default settings are pushed into reserve status as a backup program. If you are using only one of the
two programs, make sure you use Program A.
