THANK YOU for purchasing the EZ Pro™ electronic irrigation controller.
This controller offers great features in the standard models and the added
full function radio capability in the "R" models. The EZ Pro™ 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™ has to offer.
If you have questions, problems or comments on your new EZ Pro™
please call our Technical Services Department toll-free at 888-NELSON8.
Leaders in Turf Irrigation Since 1911
NOTE: In our efforts to continually improve and update our products, features
and specifications in this manual may change without notice.

INSTALLATION INSTRUCTIONS
The EZ Pro™ can be mounted indoors or outdoors. Find a location near a 120V wiring source
(230/240V for 8674, 8676, 8678, 8682, 8686, 8690, and 8694 models). Install the EZ Pro™ near eye
level if possible. Use the supplied template to mark and pre-drill pilot holes in the wall. The middle two
hole guides in the EZ Pro™ are vertically aligned for mounting the controller to a stud. (See Template)
Insert screws through the holes in the case and screw each into the corresponding pilot hole in the wall.
NOTE:The front panel can be removed to aid in installation by removing the ribbon connector
from the interconnect board and pulling the front panel off its hinges.
IMPORTANT NOTE: To comply with FCC RF exposure compliance requirements, the following antenna
installation and device operating configurations must be satisfied - The antenna used for this transmitter must be
installed to provide a separation distance of at least 5 cm from all persons and must not be co-located or
operating in conjunction with any other antenna or transmitter.
Wiring the Transformer
120 VAC in United States, Canada and Mexico; 230 VAC in Europe and 240 VAC in Australia
NOTE: Refer to and follow local codes if different from these instructions.
CAUTION:Disconnect 110V (230/240V for 8674, 8678, 8682, 8686, 8690 and 8694 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 a minimum of ordinary duty or greater
duty. Live supply wires should be attached together adjacent to the terminal block. 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 8674, 8676, 8678, 8682, 8686, 8690,8694) 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). 4
INSTALLATION INSTRUCTIONS
For models 8604, 8606, 8608, 8612, 8616, 8620, 8624 (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 8674, 8676, 8678, 8682, 8686, 8690, 8694 (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™ utilize tool-less
connectors. Pull the lever into the upper position and insert the wire into the bottom. Push the
lever down to lock in the wire. The terminal strips in the EZ Pro™ controller accept 14 AWG
(1.6mm) wire or smaller.
Connecting Master Valve or Pump-Start Relay
The EZ Pro™ 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™ is equipped to operate a sensor with normally-closed leads. The sensor port on
the EZ Pro™ is the first tool-less connector on the interconnect board (see Figure 2). 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™ will resume operation
based on the selected program.

INSTALLATION INSTRUCTIONS
Connecting the batteries and starting the controller
Remove the battery access door from the rear panel. Insert two new AA Alkaline (LR6 in
Europe) batteries to the battery clips and install the battery access door. The batteries enable
the EZ Pro™ to be programmed without AC power and maintain the real time clock in the
event of a power outage. If the batteries are not installed, the controller will lose real time in
the event of a power outage. The batteries should be replaced once a year.
NOTE: Since all programs are stored in non-volatile memory, you will not lose program
settings during a power failure - even if there is no battery installed.
CAUTION:Use AA alkaline batteries only. An AA NiCad battery may leak or explode causing
personal injury or property damage.
Close the front panel, 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!
