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 three
terminals on the CCS board communication
connector.
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.
7.Use an existing hole or drill a hole and insert a
sheet metal screw in the back plate below the
communication connector.
8.Wrap the bare drain wire around the screw and
tighten the screw. This is the only location where
the shield is grounded.
9.Daisy chain the three-conductor wire between the
remaining SPUs. Connect the drain wires together
with the wire nuts (Figure 4). Follow the stripping
and connecting procedure in Step 1 through Step
8.
10.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 3 displays a typical
communication riser.
11.Make sure all the SPUs are powered and
operating properly.
Note: Be sure you observe polarity of each of the
conductors in the communication cable.
Communication Bus
Determining the Bus Address
The bus address switch sets a unique address for this
controller on the CCS communication bus. The default
address setting is 255 (all switches in the ON position).
You must change the default address.
Set address 4 for VAV SPU controllers on the CCS
Zone Bus. Table 1 and Figure 1 show VAV SPU
controller address switch settings.

End-of-Line (EOL) Terminations
Daisy-chained RS485 protocol networks require End-of-
Line (EOL) termination to reduce interference.
Interference is caused by signal reflection that
occurs when data transmissions reach the end of a bus
segment and bounce back (Figure 6). The high
baud rates on Master-Slave/Token-Passing (MS/TP) bus
applications require robust EOL termination and strict
adherence to the EOL termination rules.
On a CCS System bus or Zone bus, only one EOL
termination is required due to the fewer number
of devices on one bus and the shorter wiring length.
Specifically, the System bus must always have a system
Manager as the EOL device, and the Zone bus must
always have a Zone Coordinator as the EOL device.Figure 4: Interference

Operation
The VAV SPU controllers are supplied in a pre-
configured format. You do not need to configure the
controller. Refer to the Comfort System (CCS)
Operation Overview Technical Bulletin (LIT-12011617)
for information on operating modes.
Troubleshooting
Use the following information to troubleshoot the
System Manager and Zone Coordinator.
Power Status LED
A green LED shows the power supply status to the VAV
SPU controller. See Table 2 for a description of modes.

Communication Bus Problems
Several factors may influence the behavior of the
communication bus. In addition, certain problems can
affect the bus in multiple ways and have multiple
symptoms, which makes the exact diagnosis difficult.
For example, duplicate addresses on the bus can
degrade performance, make the device go offline, or
stop communication completely.
Incomplete Address
The SZ SPU controller must have the address switch
set to a range between 18-41 on the system
communication bus. The COBP SPU controller must
have the address switch set to 4 on the zone
communication bus. Other settings prevent the SPU
from communicating on the System Communication
bus.
Duplicate Addresses
Two or more devices on a communication bus cannot
have the same address. For example, two SPUs on the
System communication bus cannot both have the
address 4. If two devices on the same bus have the
same address, performance can degrade or serious
communication problems may occur. These problems
include the devices not coming online or all
communication stopping completely.
Check for duplicate addresses in the following ways
depending on the severity of the situation:
•If the bus performance is degraded,
check the address switch settings at the
devices with unreliable communications.
•If a specific device is not communicating,
remove the device with communication
problems and check if the device address
remains online at the System Manager or
Zone Coordinator.
•If the bus communication problems are
severe, and no communication is present
(or if you cannot determine where
communication is unreliable), partition
(disconnect and isolate a portion of the
bus for testing purposes) and test the bus
portion connected to the System
Manager and Zone Coordinator
controllers.
Fan Operation Problems
If you start up the SPU and the fan does not run, the
Simplicity® control board may not be communicating
with the controller. The Simplicity control board must
be set to address 2 on the MODBUS® protocol to
communicate with the SPU controller. You can verify
the address setting by following one simple step and
observing the LED behavior.
On the Simplicity control board, press the COMM
SETUP button twice in a half-second interval. After
about 5 seconds, the green LED indicates the current
address of the board:
•If the LED blinks once, the address is 1
and must be reset. Press the COMM
SETUP button once to move to address
2.
•If the LED blinks twice, the address is
set correctly at 2.
•If the LED blinks three times, the
address is incorrectly set to 3. Press the
COMM SETUP button once to move to
address 2.
Within a few seconds, MODBUS communication
between the Simplicity control board and SPU
controller restores and the fan starts. If the fan does not
start, repeat the process or troubleshoot the system
for communication problems (see Correcting Physical
Communication Bus Problems).

Correcting Physical Communication Bus Problems
The communication bus is subject to a number of
physical factors that can affect performance.
Consider the following list of common physical
problems that affect the communications bus:
•Check wires
-Verify wire is 22 AWG (0.65 mm) 3-
conductor, twisted, shielded cable.
-Verify shield is continuous and hard-
grounded at one end.
•Check wiring
-Check for and eliminate T-Taps (wire
configurations that create a T shape) and
star configurations.
-Ensure bus is wired in daisy-chain fashion.
-Verify that appropriate devices have three
wires entering and exiting each terminal
(devices at the ends of the trunk do not
have this wiring).
•Check EOL switch settings
-Verify the zone bus EOL switch on the Zone
Coordinator is set to ON and the Zone
Coordinator is located at the end of the
zone bus trunk.
-Verify that only the EOL switch at the end of
the system bus is set to ON and all other
system bus EOL switches are set to OFF.
•Check connections, polarity, and lengths
-Verify communications loops are less
than approximately 304 m (1,000 ft)
total in length
-If you are using one transformer to
power multiple devices, verify the
device 24 VAC power connection
follows the polarity of the common and
24 V terminations (see Power Wiring).
•Check for opens and shorts
•Check terminations
•Check addresses
-Check for duplicate addresses
-Verify the address range is sequential
•Check for sources of interference
•Check status LED to verify power at the
controller
•Check bus voltages:
-(+) to COM must be within 2.0 to 3.0 VDC
-(-) to COM must be within 1.5 to 2.54 VDC
-(+) to (-) must be within 0.3 to 1.0 VDC
Note: Values may fluctuate due to ongoing
communications; this operation is normal
provided the voltage is within the defined range.
