13.3 CONTROL WIRING

(See Figure 5)
If the low voltage control wiring is run in conduit with the power supply, Class I insu-
lation is required. Class II insulation is required if run separate. Low voltage wiring
may be run through the insulated bushing provided in the 7/8 hole in the base
panel, up to and attached to the pigtails from the bottom of the control box. Conduit
can be run to the base panel if desired by removing the insulated bushing.
A thermostat and a 24 volt, 40 VA minimum transformer are required for the control
circuit of the condensing unit. The furnace or the air handler transformer may be
used if sufficient. See the wiring diagram for reference. Use Table 5 to size the 24
volt control wiring.
