Introduction
ISM Sprinkler Timer
Thank you for purchasing a Rain Bird ISM
Sprinkler Timer. This manual shows how to
install, program, and operate your irrigation
system timer (sometimes called a “control-
ler”). Please read these instructions carefully
and keep this manual in the slot behind the
timer for future reference.
The Rain Bird ISM is a compact, easy-to-use
sprinkler timer that offers the following
features:
• Three programs, with independent
watering days
• Up to four watering start times per
program
• Option to set any day of the week as a
watering day
• Seasonal adjust feature across all
programs
• Battery backup to retain time, date, and
programming during power outages
• Three-year Customer Satisfaction Policy
Sprinkler Timer Stations
The Rain Bird ISM is an electronic timer that
controls when your sprinkler system turns on,
and how long the sprinklers run.
The ISM can control 4, 6 or 9 watering
“stations” (depending on the model). A
station is a series of sprinklers, or other
irrigation devices, connected to a common
remote control valve. When the valve
receives a signal from the timer, the valve
opens and turns on the sprinklers connected
to it.
This illustration shows a diagram of a station
layout. Station 1 is currently watering. When
station 1 finishes, the timer shuts it off and
turns on station 2. When station 2 finishes
watering, station 3 begins, and so on.

What Is a Program?
Programming is the process of telling the
timer exactly when and how long you want to
water. The timer opens and closes the
remote control valves for each station
according to the program you set.
The ISM offers three independent programs;
A, B and C. Each program controls from one
to nine stations, and lets you customize your
watering schedules to meet the needs of
different types of plants, soil conditions,
slopes, shady or sunny areas, etc.
You will need to understand the following
terms to successfully program your ISM
sprinkler timer.
• Watering day cycle - The period of days in
which the timer repeats the program you
set. For example, a 5-day cycle is a
weekly schedule that repeats once every
five days. A 2-day cycle repeats every
other day.
• Days to water - The specific days within
the watering day cycle when watering
takes place. In a 7-day cycle, you may
select multiple watering days within the
cycle. For example, you might water on
day 1 (Monday), day 3 (Wednesday), and
day 5 (Friday). In a 2, 3, 4, 5 or 6-day
cycle, day 1 is always the only watering
day. A 2-day cycle waters on day 1, skips
a day, and then waters again on day 1 as
the cycle repeats. A 3-day cycle waters on
day 1, skips 2 days, and then repeats.
• Watering Start time - This is the time the
first station in a program begins watering.
All other programmed stations then follow
in sequence. Each program may have up
to four start times. For example, a pro-
gram could begin watering at 6:00 a.m.,
10:00 a.m., 12:00 noon, and 6:00 p.m.
NOTE: The term “watering start time”
refers to the time the program
begins - not duration of time that
each station will run.
• Duration - The number of minutes that
each station runs.

Sprinkler Timer Basics
Programming Under Battery Power
If you wish, you can program the timer under
battery power. This feature can be useful if
the timer is installed in an area that is not
readily accessible. This feature also allows
you to enter program information before
installing the timer.
To program the ISM sprinkler timer under
battery power, you must first install the
battery.
NOTE: To save battery power, the ISM
goes into “sleep” mode after a
period of inactivity on the program-
ming dial or buttons. Press any
button once to reactivate the timer.

Installing the Battery
The battery back-up feature retains time,
date, and programming information during
power outages. The battery also lets you
program the timer under battery power
before it is connected to an AC power
supply.
For best results, use a long-life, 9-Volt
alkaline battery. A new battery will normally
provide power for up to one year. Replace
the battery yearly to ensure an uninterrupted
power supply.
NOTE: Make sure the timer is
connected to an AC power supply
when replacing the battery, or you
will lose all programming information
including date and time.
To install the battery:
1. Remove the timer’s lower access cover to
expose the battery compartment.
2. Snap the two-wire battery clip onto the
terminals of the new battery. If you are
replacing an old battery, dispose of the old
battery properly.
3. Insert the new battery snugly into the
battery compartment.
4. Replace the lower access cover.
NOTE: If no battery is installed, short
circuit detection may not function as
desired. Please ensure the battery is
installed prior to the operation.

Controls and Indicators
This illustration shows the programming
controls on the face of the ISM sprinkler
timer. These controls include:
1. Liquid Crystal Display (LCD) - During
normal operation, displays the time of day
and the programs that will run today.
During programming, shows the results of
your commands. During watering, shows
the station that is running, the minutes
remaining in the station’s run time, and
whether another program is waiting to
water.
2. Up and Down (+) or (-) buttons - Set start
times and days, and make programming
changes.
3. Enter button - Enters programming
commands, and starts manual operation.
4. Prog ABC button - Selects watering
program A, B or C.
5. Programming Dial - Turns the timer off or
on and selects other programming
functions.
