INSTALLATION INSTRUCTIONS
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.
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).
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
INSTALLATION INSTRUCTIONS
For models 8374, 8376, 8379, 8382 (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.

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 pumpstart 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
