Controller Stations
The controller has several stations as shown in the illustration below. Each station is connected to a remote control sprinkler valve. The valve opens when it receives a signal from the controller, and the
sprinklers connected to the valve turn on. When these sprinklers have run for their allotted time, the
controller shuts off the valve and opens the next valve in sequence.
For example, the illustration shows that station 1 is currently watering. When station 1 is finished, the
controller will shut it off and start station 2. In the same way, station 3 will begin watering when station 2
is finished.

The illustration shows the programming controls on
the face of the ESP-Si. These controls include:
Ê LCD Display — during normal operation, displays
the time of day; during programming, shows the
results of your commands; during watering,
shows the station that is running and the minutes
remaining in its run time.
Ë Arrow ON-OFF Buttons — used to set times and
days, and to make program changes.
Ì A / B Program Button — used to select watering
program A or B. (On some ESP models, this button is labeled PGM.)
Í Manual Start / Advance Button — used to start
the irrigation program manually or to manually
advance watering from one station to the next.
Î Programming Dial — used to turn controller off
and on, and for programming.

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 operation 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.
Programming Checklist
To program the ESP-Si controller for the first time, we recommend that you complete the following
steps in order:
Fill out Program Schedule Sheet........................page 4
Set station run times.............................................page 7
Set watering start times.......................................page 8
Set controller to automatic operation..................page 9

Fill Out Program Schedule Sheet
Before you begin programming, fill out the ESP
Controller Program Sheet and attach it to the label on the
inside of the controller door. A sample Program Sheet is
shown in this illustration.
Ê Enter a brief description of each station on the con-
troller.
Ë In the Program A column, mark the watering schedule.
Either circle one of the fixed intervals, or fill in the watering days in the “Custom” row.
Ì Enter the starting time(s) for Program A. You may
have up to three separate start times for each program.
Í Enter the run time for each station assigned to Pro-
gram A. Enter “0” for stations that are not used in Program A.
Î Repeat steps 2 - 4 for Program B. If you are using a
fixed schedule, Program B will have the same watering days as Program A.

Select Watering Schedule
The ESP-Si has two types of watering schedules, either
fixed or custom. The fixed schedule sets watering to occur every second, third, or fifth day. The custom schedule lets you select specific days of the week on which
watering is to occur.
The type of schedule you select applies to both programs, A and B. For example, you cannot set Program A to a fixed schedule and Program B to a custom schedule.
Ê To use a fixed schedule, move the Schedule Slide
Switch to one of the FIXED positions:
2 = every other day
3 = every third day
5 = every fifth day
Ë To use the custom schedule, move the Schedule Slide
Switch to the “C” position.

current day to “2.” If you’re using a three-day
schedule and you want to start tomorrow, set the
current day to “3.”

Select Program
The ESP-Si controller has two programs, A and B.
Each program operates independently.
If you are using the custom watering schedule,
each program can have different watering days.
For example, Program A might run on Monday,
Wednesday, and Friday; Program B on Tuesday,
Thursday, and Saturday.
If you are using a fixed watering schedule, both
programs will have the same “ON” days. For example, if you are using the three-day fixed schedule, Program A and Program B will both run every
third day.
You can assign any station to Program A, Program
B, or both.
uThe program that is currently selected appears in
the far left corner of the display. The display will
show either “PGM A” or “PGM B.”
vTo select the program, press the A / B (or PGM)
button until the program you want appears in
the display. Pressing the A / B button switches
back and forth between the two programs.
