MOUNTING THE CONTROLLER TO A WALL

All necessary hardware is included for most installations.

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

secure a 1" (25 mm) screw into the wall. Note: Install screw

anchors if attaching to drywall or masonry wall.

2. Align controller with the screw and slide the keyhole

on top of the controller over the screw.

3. Secure controller in place by installing screws in the holes.

For PC-401-A: If the supply cord is damaged, it must be

replaced by the manufacturer or service agent or a similarly

qualified person to avoid hazard.

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.

The 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 re hazard. This device is not

intended for use by young children. Never

let children play with this device.

CONNECTING AC POWER

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.

Outdoor Cabinet

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

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

2. Connect the wires to the transformer wires located inside the

junction box. International units are supplied with a built

terminal strip. Always use a UL listed conduit ½" (13 mm) male

adapter when installing the AC wiring.

3. Insert the adapter into the ½" (13 mm) hole at the bottom of the

controller. Attach a nut to the adapter inside the enclosure.

4. 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.

Always use UL listed ½”( mm) conduit

wiring. Pro-C/PCC controllers are

intended to be supplied AC power with a

A rated overcurrent protected device.

INSTALLING STATION MODULES

The Pro-C controller is supplied with a factory-installed base

module for up to 4 stations. Additional modules may be added in

increments of 3 stations (PCM-300), 9 stations (PCM-900), or

16 stations (PCM-1600). In total, a conventionally wired system

can be expanded up to 23 stations. Additional modules are sold

separately.

The Pro-C is also compatible with the EZ Decoder System

(EZDS) for hybrid conventional and two-wire operations. Add

a Pro-C Decoder Module (PC-DM) to enable control for up to

32 total stations. This system uses the same EZ-1 decoders

used with ICC2 and HCC controllers. For more installation and

programming details, please refer to the PC-DM Installation

Guide.

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 once or at the same time by simply pushing

the “Power Lock” slide.

1. Slide the “Power Lock” into the “Power Off” (unlocked)

position. Insert the PCM or PC-DM modules into the

appropriate sequential position in the controller cabinet.

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 on the

back of the facepack or cycle power to the controller.

NOTE: To expand your controller to  or

 stations with a PCM- or PCM-,

respectively, install one PCM- in the

rst expansion slot (stations –). Then

install the PCM- or PCM- in the

upper two expansion slots. These modules

will not t or operate in any other station

output slot.

CONNECTING STATION 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. 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 the valve common wire to “COM” (Common) terminal.

Attach all individual valve control wires to the appropriate

station terminals.

COM

NOTE: The common terminal screw has

moved from the base module and is

now below the sensor terminals. Do not

connect the incoming common wires to

the P/MV terminal.
