NOTE
: ABCD bus wiring only requires a four--wire connection; however, it is
good practice to run thermostat cable having more than four wires in the event of a
damaged or broken wire during installation.
Each communicating device in the Infinity Zone System has a four--pin connector
labeled ABCD. It is recommended that the following color code be used when
wiring each device:
A — Green = Data A+
B — Yellow = Data B--
C — White = 24VAC (Com)
D — Red = 24VAC (Hot)
A B C D
A03193
It is not mandatory that the above color code be used, but each ABCD connector in
the system MUST be wired consistently.
NOTE
: Some outdoor units, typically those with multiple compressor stages,
provide their own low--voltage power source and do not require the “C” (24VAC
common) and “D” (24VAC power) connections. See the outdoor unit installation
instructions for more information.
