INSTALLING 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 expansion slot
(stations 4-6) and the PCM-900 in the upper two expansion slots.
The Pro-C utilizes automatic module recognition firmware 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.
Installing PCM Modules
The Pro-C controller is designed with a simple to use Power Lock feature
that assures that the modules are energized and firmly secured into the
controller. The Power Lock can unlock or lock all modules at one time by
simply pushing the Power Lock slide.
1. Slide the Power Lock into the Power Off (unlocked) position. Insert
the PCM modules into the appropriate sequential position in the
controller cabinet.
Note: Your Pro-C controller is designed to work only in conjunction
with BLACK PCM expansion modules.
2. Once all of the modules are in
place, slide the Power Lock into
the Power On (locked) position
to energize and secure the
modules into the controller.
3. The Pro-C will automatically
recognize the correct number
of stations. It is not necessary
to press the reset button or
cycle power to the controller.
PCM-300 PCM-900 (Must be installed in the
9-12 station module slots and used
along with one PCM-300 Module)

6
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.

CONNECTING THE BATTERY (optional) .........................................................................................
CONNECTING A MASTER VALVE ..........................................................................................
NOTE: Complete this section only if you have
a master valve installed. A master valve is a
normally closed valve installed at the supply
point of the main line that opens only when the
automatic system is activated.
1. At the Master Valve, attach the common wire to either solenoid
wire of the valve. Attach a separate control wire to the remaining
solenoid wire.
2. Route the wires into the controller.
3. Connect either wire from Master Valve to the P/MV terminal.
Connect remaining wire to the “COM” (Common) terminal.

1. Route a wire pair from the pump relay into the controller housing.
2. Connect the pump common wire to the terminal slot “COM”
(Common) and the remaining wire from the pump relay to the P/MV
screw slot.
Relay holding current draw must not exceed .28 amps (24 VAC).
Do not connect the controller directly to the pump –
damage to controller will result.
NOTE: Complete this section only if you have a pump
and pump start relay installed. A pump start relay is an
electronic device that uses a signal current from the
irrigation controller to activate a pump to provide water
to your system.
When a pump is to be operated by the controller, a pump start relay is
typically used. Hunter offers a full range a pump start relays for most
applications.

A Hunter Mini-Clik® rain sensor or other type of micro-switch weather
sensor may be connected to the Pro-C. The purpose of a rain sensor is
to stop watering when precipitation is sufficient.
1. Route the wires from the rain sensor up through the same conduit
used for valve wiring.
2. Remove the metal jumper plate from the two SEN terminals.
3. Connect one wire to the SEN
terminal and one to the other
SEN terminal.
4. When the weather sensor has
deactivated automatic watering,

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 controls. The 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" female threaded
“Tee” in the field wiring conduit
approximately 12 feet (3.7 meters) 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.
4. Attach the red wire to the bottom most
AC1 screw slot, attach the white wire to
the upper AC2 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 the Hunter
remote control owner’s manual for further
information or contact your local Hunter
distributor for ordering information.
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 running a MANUAL ALL STATIONS cycle by activating
the system using the ONE TOUCH MANUAL START (see page 20). During
the Manual Cycle, pressing the test button on the Mini-Click will interrupt
watering.
CONNECTING A WEATHER SENSOR (continued) ..............................................................
NOTE: A manual single station cycle will override the
sensor to allow manual operation when the sensor is
active.

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 (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.
A small module connects the sensor to the controller and will auto-
matically 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.

POWER FAILURES ...................................................................................................................
Due to the possibility of power failures, the controller has non-volatile
memory to preserve the program indefinitely. There is no default program.
The Pro-C is also capable of keeping the current time and date for an
extended period of time during power outage conditions.

12
SPRINKLER SYSTEM FUNDAMENTALS .............................................................................
There are three main components that are involved with all automatic
sprinkler systems that are made today. They are the controller, valves,
and the sprinklers.
The controller is what makes the whole system operate efficiently. It is
technically the brain of the entire system, instructing the valves when to
supply water to the sprinklers and for how long to do so. The sprinklers,
in turn, will direct the water towards the surrounding plants and lawn.
A valve controls a group of sprinklers called a watering station.
These stations are laid out in a fashion according to the type of plant,
the locations of the plants, and the maximum amount of water that
can be pumped to the location. Each valve is connected via wire to the
controller. Here the wire is connected to a number that corresponds to
the valve’s station number.
The controller will operate the valves in numerical sequence, only one at
a time. When a valve has completed its watering; it will switch to the next
station that has been programmed. This process is called the watering
cycle. The information pertaining to the watering times of the individual
stations and the duration of them is called a program.

CREATING A WATERING SCHEDULE ...................................................................................
There are some guidelines that should be followed when determining
when and how long to water. These factors are the soil type, the part
of the landscape being watered, weather conditions, and the types of
sprinklers being used. A watering schedule form is included with your
Pro-C that can be used as a handy reference.
Station Number and Location – Identify the station number, location and
the type of plant that is being watered.
Watering Day – Identify whether you want to use a calendar day, interval,
or an odd or even day schedule. For a calendar day schedule circle the
day of the week in which watering is desired. For an interval schedule,
indicate the desired interval number.
Program Start Times – Indicate the time of day that the program will
begin. Each program can have 1-4 start times. However, one start time
will run an entire program. Write “OFF” for any Pump Start Time not
used.
Station Run Time – Indicate the run time (1 minute – 6 hours) for
each station. Write “0:00” for any station that you do not want to operate
in the program.
Keep this schedule in a safe place for quick reference later.
NOTE: It is usually good to water one or two hours
before sunrise. Water pressure will be at optimum
levels during the early morning and the water can
soak into the roots of the plants while evaporation is
minimal. For most plants, watering during mid-day or
in the evening may cause plant damage or possibly
mildew.
NOTE: Keep an eye out for evidence of under- or over-
watering. Over-watering is most commonly indicated
by pools of water that take a long time to soak in or
evaporate, while under-watered landscapes will show
signs of discoloring and dryness. Make programming
changes immediately when evidence is present.

14
WATERING SCHEDULE FORM EXAMPLE ...........................................................................

15
PROGRAMMING FUNDAMENTALS......................................................................................
A watering program can be created to operate
valves in numerical sequence one at a time. To
create a watering program:
1. Select a program (A, B, or C) by pressing
the button on the controller (it is
recommended to start with Program A).
2. Set a program start time (only one program
start time is required to activate a watering
program).
3. Set the run time for each valve assigned to
the program, and
4. Set the days that you would like the
watering program to run.
We have included an example that will better
illustrate the operation of a program:
Let’s say you have a program start time set for
6:00 a.m. Stations 1 and 2 are going to have a
run time of 15 minutes and station 3 is set for
20 minutes. Please note that stations 4, 5, etc.
have not been included in this program, we will
water them on separate programs.
At 6:00 a.m. the controller will activate the
watering cycle. The sprinklers on station 1
will run for 15 minutes and then shut off. The
controller will automatically advance to station
2 sprinklers. These sprinklers will also run for
15 minutes and then shut off. Then, watering
on station 3 will begin. The sprinklers will turn
on for 20 minutes and shut off. Since no times
were programmed for stations 4, 5, etc. the
controller skips them. This will conclude the
program and end the water cycle at 6:50 a.m.
As shown in the above example, only one program start time was required to run the three
different stations. The controller automatically moves to the next station without the need for
additional start times.
We realize that many consumers will have variations in their plant watering needs, so at Hunter we
equipped the Pro-C with three different programs A, B, and C. These programs are independent
of each other. However, no two programs can run at the same time. The Pro-C will automatically
stack any programs that overlap.
