Pro-C Controller
A Complete Family of Full-featured
Indoor and Outdoor Residential and
Light Commercial Controllers
For the end user, for the contractor...there has
never been a residential and light commercial
controller so remarkably easy to handle as this.
Presenting the new Hunter Pro-C Controller.
Borrowing the innovative concept of
modular design from its big brother, the ICC,
this latest addition to the Hunter product
line-up is destined to become the leading
controller in its market segment in the years to
come. Starting with a base model of 3 stations,
it is possible to expand the controller up to
15 stations simply by adding plug-in modules.
So, thereʼs no need to bring along a variety of
different-sized controllers to see which one is
best for the job. With its ability to customize
to the particular size you need, the Pro-C will
always be the right choice. Being a modular
system, the new Pro-C also makes inventory
a breeze for contractors—there are only three
different units to stock (indoor cabinets,
outdoor cabinets and station modules).
But, modularity isnʼt all this controller
has to offer, with great features such as
three programs with multiple start times,
independent day scheduling options,
“one touch” manual start and rapid advance,
a programmable event day off, robust heavy-
duty locking plastic cabinet, and superior
surge protection.
The Pro-C controller: delivering maximum
flexibility for landscapes that require a
minimal number of stations.

FEATURES AND BENEFITS
Outdoor or Indoor Models Available
A versatile controller, covering the needs
of any installation
The Pro-C controller is offered as an outdoor
model when the need for weather resistance is
required and as an indoor model for installa-
tions where protection from the elements
is available. Both models are listed with UL
and CE.
Modular Design
One controller does it all; no need to stock
or carry multiple units
Hunter is a leader in
fulfilling customer
wishes and the Pro-C
controller simply the
latest in a long history
of quality irrigation
products. Here is an
impressive controller,
with its modular
design for inventory
management, three stations factory installed,
and the ability to easily add more stations,
this is one well-conceived controller that will
satisfy both contractor and end user alike.
“Custom-tailored” to the Project. Start
with the PC-300 outdoor or PC-300i indoor
3-station controller base model and then
customize it to your project with the addition
of the PCM-300 3-station plug-in modules.
The PCM-900 9-station module can also be
added to expand the Pro-C station capacity to
15 stations. One to three additional modules
can be added covering the zone requirements
of the majority of all residential and light
Outdoors
Indoors
commercial jobs. No longer does the installer
have to spend extra money on a controller with
extra zones that arenʼt necessary.
Easy Inventory Management. Now, only
one controller need be stocked for all projects.
With its modularity, the Pro-C can be called
out as a 3-, 6-, 9-, 12- or 15-station controller
on most irrigation designs, making it the only
controller necessary to keep on hand. Simply
stock the base unit for all jobs and keep a
box of modules to easily add stations to the
controller as required.
Modular Design Eliminates Service
Hassles. When heavy electrical surges
(lightning) hit a controller, the damage it
inflicts can occur in the primary or secondary
circuitry. The Pro-C is the easiest controller
to service with its readily removable primary
power and station modules. Because of
the modular design, when clock repair is
necessary, the simple repair process is to
extract the damaged module from the unit and
replace. The contractor will find that there is
no requirement to remove the controller from
the wall.
Future Expansion. Easy addition of
stations is a component of the modular
concept. When your customers add on to their
landscapes in future projects, the Pro-C is up
to the task. The PCM station modules can be
added, to make future expansion a breeze.
Large LCD Display
Easy to read for schedule review and entry
The large LCD display simplifies
programming, making it easy to read and
verify. In low light conditions, a large display
is a welcome sight to any user.

Pro-C Controller
Non-volatile Memory
Holds programs indefinitely; excellent
insurance against unreliable power
The Pro-C has what every user of electronic
controllers has wished for: the ability to keep
all programs in memory without a backup
battery. In the event of a power failure or if
AC power is suspended from the controller by
the user, the Pro-Cʼs non-volatile memory will
maintain programs forever, without need for
a battery. Normal watering will resume when
AC power is restored.
No Battery Required
Maintain time of day up to four weeks
The circuitry of the Pro-C has such low power
consumption that the controller will accurately
track the time of day for up to four weeks
after AC power has been removed from the
controller by the user or in the event of a
power outage. This timekeeping occurs
without need for a battery. When
power is restored the controller will
continue to water, right on schedule.
The controller will also reset its
circuits to allow another 4 weeks of
time keeping.
Self-Diagnostic Electronic Short
Circuit Protection
No fuses to worry about; only faulty
stations stop watering
The Pro-C automatically skips shorted
stations allowing the rest of the system
to operate as normal. The self-diagnostic
electronic short circuit protection system is
very beneficial to the user because of its ability
to aid in identifying field wiring problems.
It is almost as if the controller can trouble-
shoot the system itself.
The self-diagnostic system detects a high
current path—a “short”—through an operating
station (the most common causes of shorts
are faulty solenoids or when a bare valve
common wire touches a bare station control
wire). When a short circuit is detected on
a station, instead of blowing a fuse which
would shut down the entire irrigation system,
the controller will skip over that station and
continue to water the rest of the zones in
the program. The controller will indicate
what zone is shorting by showing the station
number followed by ERR in the LCD display.
The controller will continue to “jump over”
that zone during every watering until the
zone is repaired. To remove the ERR message
from the display, just turn the dial or push
any button.

Intuitive Dial Programming
For easy program entry
For contractors and homeowners alike, the
Pro-C provides step by step programming.
No complicated entry functions or repetitive
keystrokes. Just turn the dial to the section
of the program that needs to be changed and
use the plus, minus and next buttons to make
the adjustments. No other programming
method is easier.
Removable Front Panel for
Remote Programming
Set the controller up without having to
stand in front of it
A removable hinge design
allows easy removal of
the front panel without
disturbing field wiring.
With the use of a 9-volt
battery, you can set the
program away from the
cabinet location. This
timesaving feature allows the contractor to
program before going out to the job (also
serves as a great sales demo when talking to a
potential client). The contractor can also give
the homeowner the front panel while the job
is being installed to allow the homeowner to
try the programming functions early on. When
it comes time to actually set up the controller,
the homeowner is completely clued in, making
the whole programming process a very
simple one.
FEATURES AND BENEFITS (continued)
3 Programs (A, B, C) with
Multiple Start Times
Different watering requirements are met
with independent programming
The Pro-C allows for many different
irrigation applications using three completely
independent programs. This is ideal for
various types of plants that have separate
watering day requirements. Each program has
the ability to water up to four start times per
day. The user has complete flexibility with
watering schedules for new seed or sod lawns,
multiple cycles for low infiltration-rate soils,
slopes, morning or evening irrigation and other
watering window restrictions.
Up to Six-hour Station Run Times
Allows accurate watering for all types of
plant material
Each station will operate up to six hours of run
time in any or all three programs. Run times
from 0-120 minutes program in one-minute
increments and then in ten-minute increments
up to six hours. The factory default for all
stations is set at 0 minutes to eliminate any
unneeded stations before programming.
Note: Using the water budget feature, station
run times may only be increased to a
maximum of 6 hours.
Choice of Independent Day
Scheduling Options
Days of the week or 31-day interval for
maximum flexibility
The watering day
schedules in programs
A, B or C may be set up
independently from each
other. In each program,
the choice of Custom (day
of the week), Interval (up to 31-days), Odd or
Even days may be selected. This allows the
user to water on certain days of the week such
as Monday, Wednesday and Friday or water on
a repeating day cycle (Interval) such as every
third day, or odd/even days in any or all three
of the programs.

Pro-C Controller
365-day Calendar with Leap
Year Intelligence
True odd or even day programming
In many areas of the United States, summer
water rationing is a way of life. With its
365-day, leap year intelligent calendar the
Pro-C makes programming true Odd/Even day
watering possible, automatically correcting for
31-day months. Interval or Day of the Week
scheduling is possible as well, to cover any
watering day restrictions that may be enacted.
Superior Surge Protection
All microcircuits are protected from
electrical spikes/lightning
The Pro-C is equipped with electronic
components called MOVs (Metal-Oxide
Varistor). These MOVs are designed to shunt
electrical surges away from microcircuits
through the controllerʼs grounding circuit.
The Pro-C uses these
MOVs to protect the
controller from minor
power surges coming
in through the primary
(110/230VAC) input
side and also the
secondary output side
(24VAC).
Metal
Oxide
Varistors
Note: For proper results,
the ground circuit must
measure 10 ohms or less.
Global Water Budget/Seasonal
Adjustment
Changing run times could not be easier,
from 10% to 150%
The water budget/seasonal adjustment setting
allows the user to make global changes to the
run times of each zone from 10-150 percent
of the original programmed run time in 10
percent increments. This feature is perfect for
making small changes that are necessary as
the weather changes, without reprogramming
the entire controller. A unique bar graph
(thermometer display) in the large LCD
display lets the programmer know at a glance
what percent from the original settings the
controller is operating the station run times.
The ability to immediately view the recalcu-
lated run times for each of the zones
is another unique feature built into the
seasonal adjustment.
Note: The controller should always be initially
programmed in the seasonal adjustment
in the 100% position.

6
Weather Sensor Compatible
Built-in bypass switch eliminates
extra watering
The Pro-C allows easy connection of any
rain or weather sensor device including
the Hunter Rain-Clik™, along with other
Hunter sensors. With the sensor circuit on the
controller, wiring is fast and easy. Thereʼs a
built-in bypass switch to turn off the sensor
for maintenance. Best of all, the controller will
display Sen Off in the LCD display indicating
when the sensor is interrupting irrigation. In all
cases, use of the sensor does not
alter any programmed watering
schedule. The hookup is as
simple as removing the jumper
that is attached across the SEN
terminals of the controller and
connecting the sensor wires to
the terminals.
Programmable Event Day(s) Off
Maximum versatility when keeping the
water off is important
Need to make certain that the controller does
not water on a specific day or days of the
week? The Pro-C handles this task with ease.
When Interval programming has been selected
as the Day Schedule this event day off
programming overrides the interval function
to keep the controller always off on the day(s)
selected. For example, an interval program
is scheduled to water every third day but
Saturdays have been designated as a “mow
day,” so no watering can occur. Under the
Event Day Off selection, Saturdays can be
turned off. Sports fields, community centers,
schools and parks will find this feature satisfies
their requirements in this regard.
FEATURES AND BENEFITS (continued)
One Touch Manual Start and
Rapid Advance
Simple operation for a quick
check of zones
The One Touch Start and
Rapid Manual Advance feature
increases user-friendliness of
the controller by using fewer
steps to activate stations. This
feature is great for a quick
cycle when extra watering is
needed or if you would like to
scroll through the stations to
inspect the system.
Remote Ready
Provide your controller with simple
and reliable operation away from its
mounting location
The Pro-C is remote ready! A SmartPort®
harness is supplied with the Pro-C controller
to permit the attachment of a Hunter SRR or
ICR remote receiver. The SRR remote control
is great for residential/light commercial sites,
and offers features that other remotes canʼt
at a price that canʼt be beat. The ICR remote
control provides the installer maximum range
capability (up to 2 miles) for large commercial
sites. These easy to install remotes can save
time and money by allowing remote valve
operation away from the controller.

Pro-C Controller
Heavy-Duty Cabinet
Built to overcome the elements—
for a long time
The Pro-C is built using a robust heavy-duty
plastic UL listed and NEMA 3R rated cabinet,
which is not subject to UV degradation or
color changes. For faster installation, the
cabinet door hinge pin is removable when the
door is unlocked and open. In addition, the
cabinet uses the same professional key lock
on the outdoor model as the Hunter ICC
commercial controller. The Pro-C cabinet is
also designed with a ¾"-1" knockout option
on the back of the cabinet, and a 1" opening
for low voltage
and a ½" opening
for high voltage
in the bottom of
the cabinet to
accommodate the
wiring needs of
any job.
Programmable
0-7 Day Rain Delay
No need to return to the controller
to turn it back on
The Pro-C allows you to turn off the
controller for a predetermined period of
time (1-7 days) during rainy weather. All
programs are affected, as this delay is global.
After the specified period has elapsed, the
controller will return to automatic mode and
water as scheduled. This delay feature is very
convenient because when the controller is
turned off for an event such as rain or a social
activity, the operator will not have to make a
trip to the site to reactivate the controller. In
residential systems, when the operator uses the
watering delay feature
thereʼs no need to worry
about remembering that
the controller has been
turned off.
Programmable Delay Between Stations
Slow closing valves and well recovery will
never be an issue
A programmable delay between stations solves
the problem of slow closing valves because of
a hydraulic overload condition. The delay also
solves the problem of a system operating off of
a slow filling well, allowing the well to recover
between zones. The Pro-Cʼs programming will
allow it to fit into any situation where a delay
is necessary, as the delay is programmable up
to four hours. Delays from 0 to 60 seconds are
allocated in 5-second increments and then up
to 4 hours in 1-minute increments. Note: If the
MV circuit is programmed to operate on the
zone, it will stay hot for the first minute of any
programmed delay.

8
Pump Start/MV Circuit,
Programmable By Station
Activate a pump or master valve
only when needed
A programmable pump start circuit can
activate a pump relay or master valve by
individual zone. For systems that require
only certain zones to receive a boost in
pressure from a pump (such as rotor zones)
this programmable MV circuit feature is the
perfect solution, since it allows the pump to
only operate when needed.
Internal Junction Box
(on Outdoor Model Only)
Primary power connection made
inside the controller
No extra trips to the distributor for a forgotten
electrical box. The Pro-C comes with a
primary power junction box built inside the
cabinet. Installation time is reduced because a
J-Box does not have to be fitted and screwed
down tight. All that is required for proper
installation is electrical conduit.
24VAC Valve Test
Easy arrangement of zones during
wire hookup
When wiring up the controller so numbered
irrigation zones will run in sequential order,
installers find that an “always on” 24VAC
valve test terminal post simplifies this process.
Touching the valve wire to a hot 24 volt
terminal to determine numbered zones without
having to program a ʻmanual startʼ in the
controller makes wire installation quick
and efficient.
FEATURES AND BENEFITS (continued)
Internal
J-Box
Primary Voltage Source Choices
Indoors or outdoors, operates off a variety
of power sources
Pro-C models can be supplied with a
115VAC/60 Hz transformer for domestic use
or a 230VAC/50 Hz transformer for interna-
tional use. This versatile transformer selection
enables users to install the Pro-C anywhere in
the world.
AM/PM or 24 Hour Clock Settings
Choose your favorite method
of timekeeping
Operating the controller in either
AM/PM mode or in 24-Hour
mode is selectable by the user.
The Pro-C allows the user to
pick the time format that is most
desirable. Wherever you are in the
world, the Pro-C can operate under
local time keeping preferences.
Single Station Manual Start
If all that is needed is a little extra on a
single zone!
Many times throughout the year and for many
reasons (e.g., watering fertilizer or pesticides
into the soil, spot seeding), the user will want
to add extra water to a particular zone. With
single station manual start, the Pro-C is able
to accomplish that task. Just turn the dial to
Manual-One Station, use the arrow button
to move to the desired station, then turn the
dial to the Run position. The user may also
increase or decrease the run time setting
if preferred. After the zone is finished, the
controller will return to automatic mode with
its original schedule, even if modified for the
manual operation.
