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 Controller 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, HCC, and HPC Controllers.
For more installation and programming details, please refer
to the PC-DM Installation Guide.

The Pro-C Controller is designed with a simple-to-use
Power Lock feature that ensures the modules are energized
and rmly secured into the controller. The Power Lock
can unlock or lock all modules at the same time by simply
pushing the Power Lock slide.
1. Slide the Power Lock into the Power O (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 Controller 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.

of all valves. This is most commonly a white 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 the
conduit to one of the openings on the cabinet bottom.
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.
