INTRODUCTION .......................................................................................................................
Finally, there’s an affordable, full-featured indoor/outdoor controller for commercial applications.
Hunter Industries is pleased to introduce the ICC – Institutional/Commercial Controller for commercial use. Designed with the needs of the customer
in mind, the ICC offers simplified dial programming and an impressive range of features typically found in controllers that cost twice as much.
The ICC is very much a professional grade product. The controller’s large cabinet provides ample room for wiring. And the ICC is filled with essential
features that landscapes demand like a rain sensor bypass circuit, primary and secondary power surge protection, seasonal adjustment/water
budgeting, simultaneous program operation, programmable pump/master valve circuit, programmable rain delay, cycle and soak, four independent
programs with four different day scheduling choices and eight start times each, plus much more.
The ICC is so easy to use that you’ll need this user guide very little after installation. If you do have a question about the controller, refer to this
booklet or to the abbreviated instructions inside the door.
You can be sure that you’ve chosen with confidence. The ICC is a controller that does the job efficiently and economically.

Valve 1
Valve
Wires
1. Route valve wires between control valve location and controller.
2. At valves, attach a common wire to either solenoid wire of all valves.
This is most commonly a white colored wire. Attach a separate
control wire to the remaining wire of each valve. All wire splice
connections should be done using waterproof connectors.
3. Open hinged faceplate on the controller to access the terminal
strip area.
4. Route valve wires through the conduit and attach conduit to the
controller at the large conduit opening on the right side of the
bottom of the cabinet. The conduit opening has a triple knockout to
accommodate 1", 1¼" or 1½" (25, 32 or 40 mm) conduit. Each
section can be easily removed using a knife. Refer to the conduit
sizing chart on page 31 in the Frequently Asked Questions section if
you are not sure what size conduit will work for your installation.
5. Strip ½" (13 mm) of insulation from ends of all wires. Secure valve
common wire to C (Common) terminal on any of the valve modules
or power module. Then attach all individual valve control wires to
appropriate station terminals.
NOTE: Although it is usually best to connect all
field wires prior to powering up the controller, it is
not necessary with the ICC. After powering up the
controller, attach the common wire to the terminal
strip as described above. Then touch each wire
to the terminal marked TEST to identify the valve
location. Each valve will open electrically when
the wire is touched to the TEST terminal. After
identifying the valve location, you may then insert
the wire into the appropriate terminal. This feature
allows you to sequence the valves in the most
logical order for the user without damaging the
controller by “sparking” the wires.

CONNECTING AC POWER (ICC-800) ....................................................................................
It is recommended that a licensed electrician
perform the following power installation.
1. Remove the cover from the junction box.
2. Strip ½" off of each wire.
3. For all connections, route the wires through the conduit opening
inside the junction box
4. For 120 volt connections twist the wires together using wire nuts as
shown in Figure 1.
5. Cap any unused wires. Replace faceplate of junction box and screw
into place.

Grounding The ICC
The ICC is equipped with built-in electrical surge protection. For this
system to function properly, the earth ground terminal on the power
module must be connected to a ground rod that is driven into the earth.
Important: Use a #10 (6 mm) or #8 (10 mm) bare wire to connect the
controller to the ground rod. Use a standard copper clad, 5 /
8" (1.6 cm)
diameter, 8' (2.5 m) long ground rod.
To connect ground wire:
1. Feed the ground wire up through the large hole at the bottom of the
controller cabinet (the same hole used for the valve wires).
2. Loosen the screw on the GND terminal on the power module and
place the ground wire into the terminal. Tighten the screw so that the
ground wire is secure (see Figure 5).
CONNECTING AC POWER (ICC-801PL AND ICC-800M/ICC-800SS) ..............................

12
CONNECTING STATION MODULES ......................................................................................
The ICC controller is supplied with one factory-installed station module
for up to 8 stations. Additional modules may be added in increments of
4 or 8 stations to expand the controller’s station capability (maximum
of 32 stations with plastic cabinet and maximum of 48 stations with
metal, stainless steel cabinet or plastic pedestal). Additional modules
are purchased separately.
ICM modules now have a Positive-Lock™ feature that fastens the
module securely into the ICC. Rotating the Positive-Lock lever makes it
easy to lock or unlock the module(s).
1. When installing additional modules, you will need to turn AC power
off at the controller.
2. Rotate the Positive-Lock lever on the module clockwise to the
unlock position.
3. The module needs to be inserted into the next sequential position in
the back of the controller. Note: If you are using a 4-station module,
it must be in the last sequential position on the controller.
Example: For an area that needs 12 stations, the first module will
be an 8-station and the 4-station module will be below it. Note that
station numbers are identified on the back panel, not the individual
modules.
4. Insert the module into the controller’s expansion slot with the tab
end first (opposite side with the Positive-Lock lever).
5. Push the module into the expansion slot and rotate the lever counter-
clockwise (until the lever is flush with the side the module) to lock
the module in place.
6. Restore power to the controller. Turning the power off and on
again permits the microprocessor to recognize the newly installed
modules. You can also use the reset button on the back of the front
panel to reset the microprocessor to recognize additional modules.
Note: The Positive-Lock™ feature was added
to ICM modules date coded 12/02 or newer. The
modules will also work with older ICC units.

CONNECTING THE BATTERY (OPTIONAL) ..........................................................................
Connect a 9-volt alkaline battery (not included) to the battery terminals
and place in the battery compartment in the controller cabinet. The
battery keeps time during power outages and 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 will be retained during a power outage even if no battery
is installed.

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 via the field wire conduit.
3. Connect either wire from Master Valve to the P/MV terminal.
Connect remaining wire to the C (Common) terminal.

Pump Start Relay
To Pump
15' Minimum (4.5 m)
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.
The controller should be mounted at least 15 feet (4.5 m) away from
both the pump start relay and the pump. When a pump is to be operated
by the controller, a pump start relay must be used. Hunter offers a full
range a pump start relays for most applications.
1. Route a wire pair from the pump relay into the controller housing.
2. Connect the pump relay common wire to the terminal slot C
(Common) and the remaining wire from the pump relay to the P/MV
screw slot.
Relay holding current draw must not exceed .28 amps.
Do not connect the controller directly to the pump –
damage to controller will result.

16
Power Module
Weather Sensor
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 ICC. 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 on the power
module.
3. Connect one wire to the SEN terminal and one to the other SEN
terminal on the power module
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.
