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 - 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), 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

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.

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.
