MOUNTING THE CONTROLLER TO A WALL .......................................................................

All necessary hardware is included for most installations.

NOTE: The indoor Pro-C is not weather or water

resistant, and must be installed indoors or in a

protected area. This device is not intended for use by

young children. Never let children play with this device.

1. Select a location close to an electrical outlet or power supply that is

not controlled by a light switch.

2. Remove the front panel from the Pro-C by first removing the ribbon

connector and then pulling down the hinge release. Removing the

front panel will ease installation of the controller cabinet.

3. Use the hole at the top of the controller as a reference and secure a

1" (25 mm) screw (A) into the wall. Note: Install screw anchors if

attaching to drywall or masonry wall.

4. Align controller with the screw and slide the keyhole (B) on top of the

controller over the screw.

5. Secure controller in place by installing screws in the holes (C).

NOTE: Outdoor model is water and weather resistant.

Connecting the outdoor Pro-C to the primary power

should be done by a licensed electrician following all

local codes. Improper installation could result in shock

or fire hazard. This device is not intended for use by

young children. Never let children play with this device.

For PC-301-A:

If the supply cord is damaged, it must be replaced by the manufacturer

or service agent or a similarly qualified person in order to avoid hazard.

CONNECTING VALVES AND AC POWER ..............................................................................

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. Route valve wires through the conduit and attach conduit to one of

the openings on the bottom of the cabinet.

4. Strip ½" (13 mm) of insulation from ends of all wires. Secure valve

common wire to “COM” (Common) terminal. Attach all individual

valve control wires to appropriate station terminals.

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: It is recommended that a licensed

electrician perform the following power

installation.

Outdoor Cabinet

Route AC power cable and conduit through the ½" (13 mm) conduit

opening on the left side of the bottom of the cabinet. 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. Insert the

adapter into the ½" (13 mm) hole at the bottom of the controller. Attach a

nut to the adapter inside the enclosure.

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)

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.

9 Volt Battery

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,

OFF and sensor will appear on the

display.

Manually Bypassing the Weather Sensor

If the rain sensor is interrupting irrigation you can bypass it by using

the bypass switch on he front of the controller. Slide the switch to the

SENSOR

CONNECTING A WEATHER SENSOR (not included) ..........................................................

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.

SENSOR BYPASS position to disable the rain sensor from the system

to allow for the controller operation. You can also bypass the weather

sensor for manual operation by using the MANUAL - SINGLE STATION

function.
