Pro-C Controller
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. Open hinged faceplate on the control-
ler to access the terminal strip area.
4. Route valve wires through the conduit
and attach conduit to the controller at
the large conduit opening on the right
side of the bottom of the cabinet.
5. Strip 1⁄2" (13 mm) of insulation
from ends of all wires. Secure valve
common wire to
C
(Common) termi-
nal on the first module. Then attach
all individual valve control wires to
appropriate station terminals.
Indoor Cabinet…
Route transformer cable through the left
side of the controller and connect the wires
to the screws marked
AC
. Before closing
the compartment door make sure wires
hang in the slotted areas so that the door
can snap shut without damaging wires.
Outdoor Cabinet…
Route
AC
power cable and conduit
through the 1⁄2" (13mm) conduit opening
on the left side of the bottom of the
cabinet. Connect the wires to the trans-
former wires located inside the junction
box. International units are supplied with
a built in terminal strip. Always use a UL
listed conduit 1⁄2" (13mm) male adapter
when installing the
AC
wiring. Insert the
adapter (male threads first) into the 1⁄2"
hole at the bottom of the controller until it
enters the wiring enclosure. Attach the nut
to the adapter inside the enclosure.
Connecting 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 to expand the
controller’s station capability.
Additional modules are purchased
separately.
1. When installing additional modules,
you will need to turn off the AC power
to the controller. You should also tem-
porarily remove the 9-volt battery if
one is being used.
