Electrical — Low Voltage

Table 14.

Low Voltage Maximum Wire Length

The Low Voltage Maximum Wire Length table
defines the size and combined total maximum
length of the low voltage wiring from the
outdoor unit, to the indoor unit, and to the
thermostat.

Note:

The use of color coded low voltage wire

is recommended to simplify
connections between the outdoor unit,
the control, and the indoor unit.

Control Wire — 24 Volt

WIRE SIZE

MAX. WIRE LENGTH

18 AWG

100 FT. Combined

Table 15.

Low Voltage Hook-up Instructions

Note:

Strain relief must be provided on the inside of the air handler

cabinet for the low voltage wiring. Field supplied thermostat
wired may be wire tied as a bundle to the existing strain
relieved low voltage pigtail leads in the air handler unit.

1.

Route control wiring to unit. Remove the external sheathing of

the wiring approximately 5”.

Note:

Optional Low Voltage Conduit Entry Kit number BAYLVKIT100A

is available.

5”

2.

Remove Coil panel by turning the Phillips head door fasteners,
rotating the door away from the cabinet, disconnecting the plug,
and removing.
