THANK YOU for purchasing the EZ Pro™Jr. 8300 Series electronic
irrigation controller. The EZ Pro™Jr. 8300 Series is so “EZ”, you’ll
probably be able to install and program this feature-packed controller
without instructions. However, before installing and programming the
controller, we recommend you read these instructions carefully to take
full advantage of all the EZ Pro™Jr. 8300 Series has to offer.
If you have questions, problems or comments on your new EZ Pro™Jr.
8300 Series, please call our Technical Services Department toll-free at
1-888-NELSON8, or by visiting us on our website at LRNelson.com.

INSTALLATION INSTRUCTIONS
The EZ Pro™Jr. 8300 Series can be mounted indoors or outdoors. Find a
location near a 120V wiring source (230/240V for 8374, 8376, 8379, and 8382
models). Install the EZ Pro™Jr. near eye level if possible. Use the supplied
template to mark and pre-drill pilot holes in the wall. Insert screws through the
holes in the case and screw each into the corresponding pilot hole in the wall.
Wiring the Transformer
120 VAC in United States, Canada and Mexico; 230 VAC in Europe, and
240 VAC in Australia and South Africa
NOTE: Refer to and follow local codes if different from these instructions.
CAUTION: Disconnect 120V (230/240V for 8374, 8376, 8379, and 8382 models) power
source before wiring transformer. Complete all wiring and installation
before connecting the transformer to power source. This will avoid
accidental shorting which could damage the controller.
Power supply cables and cords used for connections are to be of ordinary
duty or greater. Low voltage output cables should be enclosed in conduit affixed
to the controller with a suitable adapter. Remove the two screws and lift out the
transformer cover to provide access to the internal transformer, bring 120V (or
230/240 for 8374, 8376, 8379, and 8382 models) wires up through 1/2" conduit
hole in the bottom of the case. (For field connection, AC wires must have an
insulation rated at 75° C minimum). Conduit should be secured to the case
(follow local codes).

INSTALLATION INSTRUCTIONS
For models 8304, 8306, 8309, 8312 (see figure 1)
Remove the transformer cover by loosening the two screws. Attach AC wires
to transformer wires using wire nuts. Also, ensure earth ground wire is
attached to green with yellow stripe ground wire. Please check local codes for
the grounding requirements in your area. Bundle wire within cable tie loop and
tighten cable tie to prevent loose wiring from touching secondary circuits. The
transformer is now wired. Replace the transformer cover and the two screws.
DO NOT turn on power yet.
NOTE: Failure to ground unit properly may cause severe damage to the
controller and/or personal property and will void warranty.

INSTALLATION INSTRUCTIONS
For models 8354, 8356, 8359, 8362 (see figure 2)
Remove the transformer cover by loosening the two screws. Route AC wires
to connector provided. Cut and trim wires to install in chassis mount
connector. Tighten the screws. (For Australia an extra clamp has been
provided.) Observe proper polarity of wires as you install them (ie. L1, L2 and
ground). The transformer is now wired. Replace the transformer cover and the
two screws. DO NOT turn on power yet.
NOTE: Failure to ground unit properly may cause severe damage to the
controller and/or personal property and will void warranty.

INSTALLATION INSTRUCTIONS
Terminal Strip
All zone, pump and sensor wire connections made inside the EZ Pro™Jr. utilize
screw type connectors that require a small screwdriver. The terminal strips in
the controller accept 12 AWG (2.1mm) wire or smaller.
Connecting Master Valve or Pump-Start Relay
The EZ Pro™Jr. is equipped with a shared circuit to operate either a pump-
start relay or a master valve. Connect one wire from the pump-start relay to
COM (common) on terminal strip, the other to PMP/MV (pump/master valve)
on the terminal strip. Refer to the pump-start relay manufacturer’s instructions
for specific installation details.
Connecting Rain/Moisture Sensor
The EZ Pro™Jr. is equipped to operate a sensor with normally-closed leads.
To install a sensor, remove the factory-installed jumper wire from the sensor
connector on the terminal strip and insert the sensor wires. Refer to the
sensor manufacturer’s instructions for specific installation details.
(See figure 2)
If a sensor has suspended watering, the sensor indicator segment will
appear on the LCD. The symbol will go off when the sensor has dried out. The
EZ Pro™Jr. will resume operation based on the selected program.
NOTE: Manual operations will ignore the rain sensor

INSTALLATION INSTRUCTIONS
Connecting the batteries and starting the controller
Remove the terminal panel under the LCD of the unit by pushing up on the tab.
Insert two new AA Alkaline (LR6 in Europe) batteries into the battery clips in the
pocket directly above the terminal strip. The AA batteries enable the EZ Pro™Jr.
to be programmed without AC power and maintain the programs and real time
clock in the event of a power outage. If the batteries are not installed, and the
Lithium battery has not been activated, the controller will lose real time and
programs in the event of a power outage. The batteries should be replaced every
five years, or when low battery symbol appears.
CAUTION: Use AA alkaline batteries only. NiCad batteries may leak or
explode causing personal injury or property damage.
Lithium Battery Backup
The EZ Pro™Jr. controllers come with a lithium battery back-up, so you will
not lose program settings or time during a power failure - even if there is no
battery installed. There will be no visual indication that this backup is working,
or when this battery is going dead. Please keep fresh Alkaline AA batteries in
the unit for the main backup battery. To activate the Lithium Battery backup,
remove the tab marked “PULL” located under the AA battery compartment.
Attach the battery/wiring cover, being sure not to damage wires. If wires are
stiff, you may find it helpful to pre-bend them. Turn on the power source.
You’re now ready to start programming!
