CCS Smart Equipment Control Board for Single Packaged
Unit (SPU) Controller
Installation Instructions
SE-SPU1011-1, SE-SPU1012-1
Applications
The new SE-SPU101x controllers replace the
RTU-100x controllers. All the RTU100x controllers are
discontinued, including the RTU-1003-0 VAV SPU
controller. T he new SEC pr oduct offering provides new
controller options.
The SE-SPU101x-1 SEC Unit Control Board (UCB) is a
member of the Smart Equipment Controller (SEC)
product family. The controller is designed to run a preengineered HVAC zoning application and provide the
inputs and outputs required for this application.
North American Emissions Compliance
United States
This equipment has been tested and found to
comply with the limits for a Class A digital device
pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection
against harmful interference when this equipment is
operated in a commercial environment. This
equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in
accordance with the instruction manual, may cause
harmful interference to radio communications.
Operation of this equipment in a residential area
may cause harmful interference, in which case the
users will be required to correct the interference at
their own expense.

Mounting
The manufacturing facility mounts the controller. All of
the required power wiring, internal unit sensor wiring,
and output wiring is completed and tested at the
factory . The control application required for the specific
UCB is factory configured and ready for operation.
Wiring
Field Wiring Connections
In addition to power connections, the UCB requires a
communication bus connection. Address selection is
required for networking with a CCS Building
Automation System (BAS).
Power Wiring
The SEC UCB controller is factory wired for 24 VAC
power.
IMPORTANT: The 24 VAC power should not be
shared with other network devices. Sharing power to
other network devices may cause noise,
interference, and ground loop problems. You may
damage the controller by sharing power to other
devices.

In certain cases, you may need to share a 24 V

transformer with multiple CCS devices. Be sure that
you maintain consistent +, -, and common wiring
terminations on the shared CCS devices.
IMPORTANT: Do not interchange +, -, and
common 24 V terminations when sharing a
transformer with multiple CCS devices.
Interchanging these terminations can cause damage
to the controller.
Setup and Adjustments
To quickly set up your CCS network:
1. On each end of the 3-conductor cable, strip the
outside insulation back approximately 2 in.
(51 mm).
2. Tear off excess foil shield, leaving the bare drain
wire and the three insulated conductors.
3. On each end of the three insulated conductors in
the cable, strip the insulation back approximately
1/8 to 1/4 in. (4 to 7 mm).
4. Choose a color pattern to follow and insert each of
the three conductors into one each of the thr ee
terminals on the CCS board communication
connector.
Note: Be sure you observe polarity of each of the
conductors in the communication cable.
Communication Bus
The UCB default address is set to 4. The available
values range from 0 to 127. To view the UCB Network
Address, use the joystick and the two push buttons
below the LCD, to navigate through the menus to the
Commissioning menu (Figure 1).
Up and down movements of the joystick move the >
cursor and scroll through the selections in the active
section of the menu (Figure 2).
5. Tighten each terminal until the wire is secure.
6. Ground the drain wire at one end only of the
communication trunk. Do this on the last unit in
line.
Use an existing hole or drill a hole and insert a
sheet metal screw in the back plate below the
communication connector.
Wrap the bare drain wire around the screw and
tighten the screw. This is the only location where
the shield is grounded.
7. Daisy chain the three-conductor wire between the
remaining SPUs. Connect the drain wires together
with the wire nuts. Follow the stripping and
connecting procedure in Step 1 through Step .
8. Run the cable from the last unit to the location of
the System Manager or Zone Coordinator. Follow
the connection instructions for the System Manger
or Zone Coordinator . Figure 4 displays an example
communication riser.
9. Make sure all the SPUs are powered and operating
properly.
Each menu selection represents either a submenu or a
property. Press Enter to display the items in the
submenu or the values of the selected property.
Once you navigate to the Commissioning menu, use
the cursor to scroll to the Network submenu. From the
Address submenu, press Enter to display the current
network address. Move up or down with the joystick to
display the values of other properties.
