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)
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.
