2.7.4.2 Remote Condensing Unit (AHU Models)
Systems equipped with a remote condensing unit
require field control wiring between the A/C system
and the condensing unit, (see Figure 8). The number of
conductors required between the two systems varies
based upon the control options provided. Refer to the
supplied electrical schematic to determine the exact
number of field wires needed and appropriate wire
terminations required for your specific system.
