13ACC units are not equipped with a 24V transformer. All
24 VAC controls are powered by the indoor unit. Refer to
wiring diagram.
Electrical openings are provided under the control box cov
er. Field thermostat wiring is made to colorcoded pigtail
connections.
1 − Compressor Contactor K1
The compressor is energized by a contactor located in the
control box. See figure 2. Single−pole contactors are used
in 13ACC series units. K1 is energized by the indoor ther
mostat terminal Y1 (24V) when thermostat demand is
present.
