ISA Timer Features and
Benefits
The ISA Sprinkler Timer is an electronic clock that
controls when your sprinkler system turns on and
how long the sprinklers run. The ISA timers offer
several advanced features, including:
• Large LCD display and easy-to-use programming
dial and buttons
• Six convenient pre-set watering schedules
• Two independent watering programs (ISA 400
models)
• Up to three watering start times per program
• Ability to control four, six, or eight watering stations
(depending on model)
• Rain-Off feature can suspend watering and retain
all programmed information

Timer Stations
Most sprinkler systems divide the yard into “stations”
(also called “zones”). You can program each station
to water for a different length of time, so the amount
of water fits the different plant types, soil conditions,
and sunny/shady areas in the yard.
Each station has an irrigation valve that runs several
sprinklers. An electric signal from the timer opens
Page 2Page 2
Page 2
Page 2Page 2
the first valve, which turns on the sprinklers
connected to it. When these sprinklers have run for
their programmed time, the timer closes the first
valve and opens the second valve.
For example, the illustration below shows that station
1 is currently watering. When station 1 finishes, the
timer will shut it off and start station 2. When station 2
finishes, station 3 begins, and so on.

Select Location
::
NOTE
: The ISA Timer is for INDOOR use
::
only. If you must install it outdoors, use a
water-resistant cabinet, such as the Rain
Bird Model TC-2 Timer Cabinet. The TC-2
is a heavy-duty, weather-resistant plastic
case that lets you convert any indoor-only
timer to outdoor use.
Select a convenient indoor location within six feet
(1,9 m) of a 120-volt AC electrical outlet (240-volt
outlet for international 50 Hz models). The mounting
location should be completely protected from
moisture, direct sunlight, and freezing temperatures.

(120 mm) apart. Leave
of each screw head protruding from the wall.
(Use plastic mounting anchors for plaster or
masonry).
Place the two keyhole-shaped slots on the back
of the timer over the screw heads. Then slide the
timer securely down onto the screws.
OPTIONAL: To further secure the timer, remove
the timer’s lower access cover by gently pulling
the cover off using the slots on the left and right

Install Battery
During a power outage, the battery preserves your
programmed watering schedules. A newly installed
battery will hold information for up to six hours if
power goes out.
English
NOTES
::
: The battery serves as memory
::
back-up only. You can program the timer
on battery power, but the system will not
water without AC power.
Replace the battery once a year. If power
outages occur frequently, you may need
to change the battery more often.

::
NOTE
: When replacing the battery,
::
DO NOT unplug the transformer or you
will lose all programmed information.
If the battery fails during a power outage, the timer
will revert to its default watering program. The default
program waters each station every day for 10
minutes, starting eight hours after AC power
resumes. The default program will continue until you
reprogram the timer.
To install the battery, remove the timer’s lower
access cover by gently prying out the cover at
the slots on the left and right sides of the timer.
Connect the terminals of a 9-volt alkaline battery
to the timer’s two-wire battery clip. (DO NOT
use a rechargeable battery). The display flashes
“AC OFF” and “8:00 AM.”
Replace the lower access cover, or connect field
wiring as described in “Connect Field Wiring” on
page 7.

Connect Field Wiring
English
Select Proper Wire
For wire runs of less than 800 feet, use 18-gauge
color-coded, multi-strand, direct burial wire. For
longer runs, use 14-gauge wire of the same type.
Choose wire that has one strand for each valve in
your system, plus one strand for the common wire.
For example, use five-strand wire if you have four
valves, seven-strand wire for six valves, etc.
Tape off spare wire strands for future system use or
troubleshooting. Wire that is buried underground
must have watertight connections and be codeapproved for underground use. Avoid placing
underground wire in places where it may be
damaged by digging or other activities.

Connect Valve Wires to Timer
Each valve connects to the timer with two wires: a
“hot wire” of its own, and a “common wire” that it
shares with the other valves.
::
NOTE
: The ISA Series Timers can be
::
used with most hydroindexing valves.
Please contact the valve manufacturer for
more information.
Page 7Page 7

Page 7Page 7
English
Remove the timer’s lower access cover by gently
prying out the cover at the slots on the left and
right sides of the timer.
Splice together one wire from each valve (usually
the white strand) to create a single “common”
wire. Connect the common wire to the terminal
screw labeled “COM.”
::
NOTE
: Make sure all wire connections
::
are tight and in firm contact with the
terminal screws. Use watertight splice
connectors to prevent corrosion and
avoid short circuits.
Connect each valve “hot” wire to a numbered
screw on the timer’s terminal strip. Connect the
wire from valve number 1 to terminal screw 1;
connect the wire from valve 2 to terminal screw
2, and so on.
CAUTION
than one valve wire to each terminal
screw. Wiring more than one valve to
each terminal will damage the timer. Also,
if you are using more than one timer, do
not share “common” wires between them.

After connecting all valve wires, replace the
timer’s lower access cover.
::
NOTE
: To save water and money, you
::
can also install a rain sensor, such as
Rain Bird’s RS-1 Rain Shut Off. The RS-1
measures rainfall and prevents
unnecessary watering.
If Using a Master Valve or Pump
Start Relay
(Optional ISA 400 Series only)
::
NOTE
: Complete this section only if you
::
are using a pump start relay or a master
valve (an automatic valve installed on the
mainline pipe upstream from the station
valves). The timer does not provide the
main power for a pump.

ISA 400 Series Timers allow a master valve or pump
start relay to operate whenever a valve is operating.
Pumps are used in some places to draw water from
a well or other source.
If you are activating a pump from the timer, you must
also install a Pump Control Relay, such as
Rain Bird’s PCR-1. The PCR-1 offers solid-state
reliability and can activate most 120- or 240-volt
pump motors up to two horsepower.
Page 9Page 9

English
Connect the color-coded “hot” wire from the
master valve or pump start relay to the timer
terminal screw marked “MV.”
Connect the common wire from the master
valve / pump start relay to the common wire
coming from the station valves. This wire
connects to the timer terminal screw marked
“COM.”
::
NOTE
: Make sure that the total draw of
::
the master valve or pump start relay plus
the draw of the valve does not exceed
0.650 Amps at 24 VAC, 60 Hz.
To avoid possible pump damage, connect a
short “jumper” wire from any unused station
terminal(s) to the nearest terminal screw in
use. For example, if you have an eight-station
timer with only four stations in use, jumper
stations five through eight to the nearest active
station (four).
