REPLACING THE BATTERY AND FUSE
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. Then close
the drawer.
The ESP-TM 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.

If the ESP-TM fuse should blow, check for short
circuits in the valve solenoids or field wiring. (For
more information, see the Troubleshooting section
on page 36.) Correct any problems before replacing
the fuse.
To replace a blown fuse, remove the old fuse from
the clips, and replace it with a 0.5-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.
