The condensing unit rating plate lists pertinent electrical data
necessary for proper electrical service and overcurrent protec-
tion. Wires should be sized to limit voltage drop to 2% (max.)
from the main breaker or fuse panel to the condensing unit.
Consult the NEC, CEC, and all local codes to determine the
correct wire gauge and length.
Local codes often require a disconnect switch located near the
unit; do not install the switch on the unit. Refer to the installa-
tion instructions supplied with the indoor furnace/air handler for
specific wiring connections and indoor unit configuration. Like-
wise, consult the instructions packaged with the thermostat
for mounting and location information.

OW OLTAGE
Condensing unit control wiring requires a nominal 24 VAC (+/-
6 VAC), 60 Hz, minimum 25 VA service from either the indoor
or outdoor transformer packaged with the optional CTK0* com-
municating thermostat kit. Low voltage wiring for the condens-
ing units depends on the thermostat used. The unit is de-
signed to work as part of a fully communicating HVAC system
utilizing the ComfortNet™, CTK0* thermostat, ComfortNet com-
patible indoor unit, and up to four wires. The unit also has
legacy 24 VAC inputs to support non-communicating systems.
Route control wires through the low voltage port and terminate
in accordance with the wiring diagram provided inside the con-
trol panel cover.
S
NOTE: If the condensing unit is wired in the communicating
mode together with the compatible communicating indoor unit
and thermostat, then the communicating thermostat is able to
search and identify the condensing unit when power is applied
to the system. Refer to the Installation Manual of the
communicating thermostat for more information.
