Mounting the Controller to a Wall

All necessa ry hardware is in cluded for most inst allations.

1. Use the hol e at the top of the controlle r as a reference and
secure a 1" (2 5 mm) screw into th e wall. Note: Install scr ew

anchor s if attaching to dr ywall or masonr y wall.

2. Align con troller with the screw a nd slide the keyhole
on top of the con troller over the screw.

3. Secu re controller in place by ins talling screws in the ho les.

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.

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 p ower cable and condu it through the ½" (13 mm)
conduit op ening on the lef t side of the bottom of th e cabinet.

2. Co nnect the wires to th e transformer wi res located inside the
junction box. International units are supplied with a built in
terminal s trip. Always use a UL listed co nduit ½" (13 mm) male
adapter wh en installing the AC wiring.

3. Insert t he adapter into the ½" (13 mm) hole at t he bottom of the
controller. Attach a n ut to the adapter inside th e enclosure.

4. Conn ect a 9-volt alkaline batter y (n ot included) to the ba ttery
terminals an d place in the batter y compartme nt in the front
panel. Th e battery allows t he user to program the co ntroller
without AC p ower. Wate ring will not occur wit hout AC power.
Since this contr oller has non-volatile m emory, the program
clock and c alendar will be retai ned during a power ou tage even
if no bat tery is installed.

Installing Station Modules

The Pro- C controller is supplie d with a factory-i nstalled base
module fo r up to 4 stations. Additi onal modules may be a dded
in incremen ts of 3 stations (PC M-300) or a singl e 9-station
(PCM-90 0) to expand the controll er’s station capabil ity to 16
stations. Additional modules are sold separately.

The Pro- C utilizes automatic mo dule recognition fi rmware to
identif y when PCM modul es are installed or rem oved from the
controller. This feat ure will recognize the cor rect number of
station s without having to rese t or cycle power to the cont roller.

Installing PCM Modules

The Pro- C controller is designe d with a simple to use “Power
Lock” featur e that assures that the mo dules are energized a nd

firmly s ecured into the control ler. T he “Power Lock” can unlo ck
or lock all m odules at one time by simp ly pushing the “Power
Lock” s lide .

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

position. I nsert the PCM mo dules into the approp riate
sequen tial position in the contr oller cabinet.

2. Once all of t he modules are in place, sl ide the “Power Lock”

into the “Power On ” (locked) position to en ergize and secure
the modul es into the controller.

3. The P ro-C will automatica lly recognize the corre ct number of

station s. It is not necessar y to press the reset but ton or cycle
power to the con troller.

The use of a PC M-900 to expand you r
controller to 1 6 stations requires t hat one
PCM-300 be in stalled in the firs t expansion
slot (st ati ons 5 –7) and the PCM-900 i n the
upper t wo expansion slots.

NOTE

Connecting Station Wires

1. Route valve wi res between contro l valve location
and controller.

2. At valves, at tach a common wire to eit her solenoid wire
of all valves. T his is most commonly a wh ite colored wire.
Attach a sep arate control wire to th e remaining wire
of each valve. All w ire splice connecti ons should be
done using wa terproof connec tors.

3. Route va lve wires through the con duit and attach co nduit
to one of the op enings on the bot tom of the cabinet.

4. Strip ½" (13 mm) of insulation f rom ends of all wires.
Secure th e valve common wire to “COM” (Common) terminal.
Attach all in dividual valve contro l wires to the appropr iate
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 dierent battery has potential for

a risk of re, explosion, and electric shock. See owner’s
manual for instructions.

Connec t a 9-volt alkaline battery (not inclu ded) to the batter y
terminals an d place in the batter y compartme nt in the front
panel. Th e battery allows t he user to program the co ntroller
without AC p ower. Wate ring will not occur with out AC power.
Since this contr oller has non-volatile m emory, the program cl ock
and calen dar will be retained d uring a power outage eve n if no
batter y is installed.

Activating the V Lithium Battery

After ins talling your Pro-C, m ake sure to remove the batte ry
contac t insulator to allow the Pro -C to keep time in the event
of a power out age.
