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 in order 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.

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.

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.

NOTE

To be performed by a licensed electrician only.

Always use UL listed ½" (13 mm) conduit with male adapter when installing AC wiring. Pro-C/PCC controllers are intended to be supplied AC power with a 15A rated overcurrent protected device.

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 in 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.

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) or a single 9-station (PCM-900) to expand the controller’s station capability to 16 stations. Additional modules are sold separately.

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.

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.

NOTE

The use of a PCM-900 to expand your controller to 16 stations requires that one PCM-300 be installed in the first expansion slot (stations 5–7) and the PCM-900 in the upper two expansion slots.

10

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.

NOTE

Common terminal screw has moved from base module and is now below the sensor terminals. Do not connect the incoming common wires to the PM/V terminal.

Connecting the Battery (optional)

WARNING: RISK OF FIRE, EXPLOSION, AND ELECTRIC SHOCK. REPLACE BATTERY WITH CR2035 TYPE ONLY. Use of a different battery has potential for a risk of fire, explosion, and electric shock. See owner’s manual for instructions.

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.

Activating the 3V Lithium Battery

After installing your Pro-C, make sure to remove the battery contact insulator to allow the Pro-C to keep time in the event of a power outage.

NOTE

When installing 3V Lithium battery, ensure the positive (+) side is facing up.
