Connecting AC Power
Indoor Cabinet
Route transformer cable through the hole on the bottom left
side of the controller and connect one Yellow Wire to each of the
screws marked AC and the Green Wire to GND.
NOTE
To be performed by a licensed electrician only.
Always use UL listed ½" (13 mm) conduit with male adapter
when installing AC wiring. Pro-C/PCC controllers are intended
to be supplied AC power with a 15A rated overcurrent
protected device.
Outdoor Cabinet
1. Route AC power cable and conduit through the ½" (13 mm)
conduit opening on the left side of the bottom of the cabinet.
2. Connect the wires to the transformer wires located inside the
junction box. International units are supplied with a built in
terminal strip. Always use a UL listed conduit ½" (13 mm) male
adapter when installing the AC wiring.
3. Insert the adapter into the ½" (13 mm) hole at the bottom of the
controller. Attach a nut to the adapter inside the enclosure.
4. Connect a 9-volt alkaline battery (not included) to the battery
terminals and place in the battery compartment in the front
panel. The battery allows the user to program the controller

a risk of re, explosion, and electric shock. See owner’s
manual for instructions.
Connect a 9-volt alkaline battery (not included) to the battery
terminals and place in the battery compartment in the front
panel. The battery allows the user to program the controller
without AC power. Watering will not occur without AC power.
Since this controller has non-volatile memory, the program clock
and calendar will be retained during a power outage even if no
battery is installed.
Activating the V Lithium Battery
After installing your Pro-C, make sure to remove the battery
contact insulator to allow the Pro-C to keep time in the event
of a power outage.

Connecting a Hunter “Clik” Weather Sensor (not included)
A Hunter weather sensor or other micro-switch-type weather
sensors can be connected to the Pro-C. The purpose of this
sensor is to stop automatic watering when weather conditions
dictate.
1. Remove the metal jumper plate that is attached across
the two SEN terminals inside the controller.
2. Connect one wire to
one SEN terminal, and the
other wire to the other
SEN terminal.
When the weather sensor
has deactivated automatic
watering, “OFF” will appear
on the display.

15
Connecting a Hunter “Clik” Weather Sensor (continued)
Testing the Weather Sensor
The Pro-C provides simplified testing of a rain sensor when
the sensor is wired into the sensor circuit. You can manually
test proper operation of the rain sensor by using the One
Touch Manual Start (see page 25). During the Manual cycle,
pressing the test button on the “Clik-type” sensor
(e.g., Mini-Clik®)will interrupt watering.
NOTE
The Manual single-station function ignores any attached sensor
and will allow watering to occur.
Manually Bypassing the Weather Sensor
If the rain sensor is interrupting irrigation,
you can bypass it by using the bypass switch
on the front of the controller.
Slide the switch to the Bypass position
to disable the rain sensor from the system to
allow for controller operation. You can also bypass the weather
sensor for manual operation by using the Manual function.
The Bypass switch does not affect the Seasonal Adjust update
when using the Solar Sync sensor.

16
Connecting a Hunter Remote (not included)
The Pro-C is compatible with Hunter remote controls.
The SmartPort wiring harness (included with all Hunter
remotes) allows for fast and easy use of Hunter controls.
Hunter remotes make it possible for you to operate the system
without having to walk back and forth to the controller.
To Install the SmartPort Connector
1. Install a ½" (13 mm) female threaded “Tee” in the field
wiring conduit approximately 12" (30 cm) below the Pro-C.
2. Feed the red, white, and blue wires of the harness
through the base of the “Tee” and into the wiring
compartment as shown.
3. Screw the SmartPort harness housing into the “Tee”
as shown.
NOTE
P/N 258200 can be used as an alternate method
to mount the SmartPort connector.
4. Attach the red wire to the screw slot marked AC1, attach
the white wire to the screw slot marked AC2, attach the
blue wire to the screw slot marked REM.
NOTE
Reversing the red and white wires will result in an
“SP ERR” message.

17
Connecting a Hunter Remote (continued)
NOTE
Any extension of the wiring on the SmartPort®may result in an
error message in the controller display and possible malfunction
of the remote unit due to radio interference. In some situations,
lengthening of the harness may work fine, in others it may not
work at all (it is site specific). In either case, extending the wiring
harness should be done using shielded cable to minimize the
possible effects of electrical noise. For easiest installation,
order the Hunter SmartPort shielded cable wiring harness
(P/N ROAM-SCWH) with a full 25' (7.6 meters) of
shielded cable.

Connecting to the Hunter Solar Sync®
The Solar Sync is a sensor system that, when connected
to Hunter Pro-C, will automatically adjust your controller
watering based upon changes in local climate conditions.
The Solar Sync utilizes a solar and temperature sensor
to measure on-site weather conditions used to determine
evapotranspiration (ET), or the rate at which plants and turf
use water. In addition, the Solar Sync sensor includes
a Hunter Rain-Clik and Freeze-Clik sensor that will shut down
your irrigation system when it rains and/or during freezing
conditions.
The controller will automatically increase or decrease watering
run times based on changes in weather. The result is a new
water-efficient irrigation product that promotes water
conservation and healthier plants. You simply program your
controller like you normally would, and the Solar Sync takes
over from there, eliminating the need to manually adjust your
watering schedule.
For installation and programming instructions of your Hunter
Solar Sync, please refer to the Solar Sync owner’s manual.

eliminates the need to enter a start time for each station.
4. Press the ibutton to add an additional start time,
or n button for the next program.
Eliminating a Program Start Time
With the dial set to the START TIMES position, push the j
and kbuttons until you reach 12:00  (Midnight). From this
position push the kbutton once to reach the “OFF” position.
NOTE
All stations operate in numerical order. Only one program start
time is required to activate a watering program.
If a program has all four start times turned off, then that
program is off (all other program details are retained).
Because there are no start times, there will be no watering
with that program.
