CONNECTING STATION MODULES ......................................................................................
The Pro-C controller is supplied with a factory-installed base module
for up to 3 stations. Additional modules may be added in increments
of 3 stations (PCM-300) or a single 9-station (PCM-900) to expand the
controller’s station capability to 15 stations. Additional modules are
sold separately.
Note: The use of a PCM-900 to expand your controller to 15 stations
requires that one PCM-300 be installed in the first slot
(stations 4-6) and the PCM-900 in the upper two slots.
The Pro-C utilizes automatic module recognition firmware (Pro-C
controllers manufactured Nov. 2003 and after) to identify when PCM
modules are installed or removed from the controller. This feature will
recognize the correct number of stations without having to reset or cycle
power to the controller.
The Pro-C controller is designed with a simple to use Easy-Lock™
feature that assures that the modules are firmly secured into the

CONNECTING A WEATHER SENSOR (NOT INCLUDED) ...................................................
A Hunter Mini-Clik® rain sensor or other type of micro-switch weather
sensor may be connected to the Pro-C. The purpose of this sensor is
to stop watering when precipitation is sufficient. The sensor connects
directly to the controller and allows you to easily override the sensor by
using the Rain Sensor bypass switch on the controller.
1. Route the wires from the rain sensor up through the same conduit
used for valve wiring.
2. Remove the jumper from the two SEN terminals.
3. Connect one wire to the SEN terminal and one to the other
SEN terminal.
NOTE: If the rain sensor switch is left in the ACTIVE
position and no sensor is connected and the jumper
has been removed, the display will read SEN OFF
and no irrigation will occur. To eliminate this
problem when no sensor is connected, leave the
switch in the BYPASS position or install a short
jumper wire between the sensor terminals.

CONNECTING A WEATHER SENSOR (CONTINUED).........................................................
CONNECTING AN SRR OR ICR REMOTE CONTROL (NOT INCLUDED) .........................
1/2" Thread
To Controller
Pre-assembled Assembled
The Pro-C controller is shipped with a SmartPort® wiring harness,
allowing for fast and easy use of the Hunter SRR, or Long Range ICR
remote controls. The SRR and ICR make it possible for contractors and
end users alike to operate a system without having to walk back and forth
to the controller.
To utilize the SRR or ICR Remote
Control System you must install the
SmartPort outlet.
1. Install a " female threaded
“Tee” in the field wiring conduit
approximately 12" 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 in Fig. 1.
3. Screw the SmartPort harness
housing into the “Tee” as shown
in Fig.1.
4. Access the terminal strip area and
attach the red wire to the bottom most
AC screw slot, attach the white wire to
the upper AC screw slot and attach the
blue wire to the screw slot
marked REM.
The SmartPort is now ready for remote
control use. Please refer to either the
SRR or ICR owner’s manual for further information or contact your local
Hunter distributor for ordering information.
NOTE: If the sensor interrupts a watering cycle
and resets before the cycle would have finished,
the remaining portion of the watering cycle is
terminated.
Testing a Weather Sensor
The Pro-C provides simplified testing of a rain sensor when the rain
sensor is wired into the sensor circuit. It also provides the user the
ability to override the rain sensor when necessary to perform system
inspections and manual watering.
• Testing the Rain Sensor
The user can manually test the proper operation of the rain sensor
by running a manual “all stations cycle” or by activating the system
using the one touch manual method. During a manual cycle,
pressing the test button on the Mini-Clik® will interrupt watering.
• Overriding the Rain Sensor
The SRR remote control device (single station operation only,
not programs A, B, or C) and manual single station function on the
Pro-C dial will override the rain sensor. This function provides the
users the ability to operate the system even though the rain sensor
has shut the system off.

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 a new Hunter SmartPort shielded cable wiring
harness (part #SRR-SCWH) with a full 25 feet of
shielded cable.

POWER FAILURES ..............................................................................................................................
With the Irrigation Management and Monitoring System™ (IMMS™),
automatic irrigation systems at multiple sites or multiple controllers
on a single site can be programmed for functions that would typically
be handled directly at each site’s controller. Scheduling of days to water,
run times, start times, cycle and soak operations and more can now
be done from a single computer at a desk miles away from the
actual installation.
In addition, scheduled operation of non-irrigation components also in
use at these sites – e.g., lighting systems at athletic fields, fountains
at shopping centers – as well as pumps and sensors can also be
programmed and monitored from a single central location.
A key function of the IMMS is its ability to monitor changing conditions.
With the aid of such options as flow sensors, rain sensors and other
weather-sensing devices, the IMMS can receive reports on the current
condition at every site it is linked with and then respond with the
necessary adjustments should any of those conditions go beyond the
limits that have been defined.
CONNECTING TO THE HUNTER IRRIGATION
MANAGEMENT AND MONITORING SYSTEM™ ...........................................................................
No system available today is more cost-effective than the Hunter IMMS.
It’s inexpensively priced and contains the most essential features needed
for water management. It’s able to team with any or all of the standard
automatic controllers in the Hunter line-up, from the SRC to the Pro-C to
the ICC. Plus, it’s a system that’s easy and affordable to upgrade, making
it possible to accommodate an expanding network
of controllers.
For more information on the IMMS, contact your local Hunter dealer.
Due to the possibility of power failures, the controller has non-volatile
memory to preserve the program indefinitely. There is no default program.
