REPLACING THE BATTERY AND FUSE
The ESP-Si controller features a battery backup,
which will preserve the controller’s program in the
event of a power failure. Under normal conditions,
the lithium battery will last well over a year. For
maximum protection against loss of programming
data, Rain Bird recommends that you replace the
lithium coin cell battery once a year.
In addition, if a short circuit occurs in the sprinkler
system, you may have to replace the fuse.
Œ
Remove the controller’s lower face panel by
gently prying out the panel at the slots on the
left and right sides.
•
To replace the battery, pull out the battery
drawer and remove the old battery. Install a new
3-Volt lithium coin cell battery in the drawer. Be
sure the positive (“+”) side of the battery is fac-
ing
down
in the drawer. Then close the drawer.
Ž
If the ESP-Si fuse should blow, check for short
circuits in the valve solenoids or field wiring.
(For more information, see the Troubleshooting
section on page 34.) Correct any problems be-
fore replacing the fuse.
To replace a blown fuse, remove the old fuse
from the clips, and replace it with a 1.0-AMP,
250-Volt FAST BLO fuse.
•
To reinstall the face panel, align the rounded
posts on the inside of the panel with the sleeves
inside the cabinet. Also align the Schedule Slide
Switch with the internal switch on the circuit
board. Then gently press the face panel until it
clicks into place.

INSTALLING THE CONTROLLER
Select Location
ESP-Si controllers are designed for indoor mounting only. For best results, mount the controller at eye level.
Allow approximately 7 inches (18 cm) of clearance to the left side of the controller so the controller door can
swing fully open. In addition, mount the controller within 5 feet (1,5 m) of a 117-Volt AC power outlet so the
wires from the external transformer can be easily connected to the controller.
The ESP-Si controller has three “keyhole” slots on the back of the cabinet. Use these slots to mount the con-
troller to a flat wall or vertical stud. Always use lower mounting hole “D” to secure the bottom of the controller.
