overcurrent protection specified on the unit rating plate. An
electrical disconnect must be provided at the furnace location.
NOTE: Line polarity must be observed when making field
connections.
Connect hot, neutral, and ground wires as shown in the wiring
diagram located on the unit’s blower door. Line polarity must
be observed when making field connections. Line voltage
connections can be made through either the right or left side
panel.

HUMIDIFIER WIRING
Accessory wiring connections are to be made through the 1/4”
quick connect terminals provided on the furnace integrated
control module.
The Humidifier and Electronic Air Cleaner
hot and neutral terminals are identified as HUM and EAC. All
field wiring must conform to applicable codes. Connections
should be made as shown below.
Accessory Wiring
If it is necessary for the installer to supply additional line
voltage wiring to the inside of the furnace, the wiring must
conform to all local codes, and have a minimum temperature
rating of 105°C. All line voltage wire splices must be made
inside the furnace junction box.
The integrated control module humidifier terminals (HUM)
are energized with 115 volts whenever the induced draft
blower is energized. The integrated control module electronic
air cleaner terminals (EAC) are energized with 115 volts
whenever the circulator blower is energized.
24 VOLT THERMOSTAT WIRING
NOTE:
Low voltage connections can be made through either
the right or left side panel. Wire routing must not interfere
with circulator blower operation, filter removal, or routine
maintenance.
A 40 V.A. transformer and an integrated electronic control are
built into the furnace to allow use with most cooling equipment.
Consult the wiring diagram, located in the Technical Manual
or on the blower door for further details of 115 Volt and 24
Volt wiring.
THERMOSTAT WIRING - SINGLE-STAGE
The following drawing illustrates the typical field wiring for
a heat only single stage system and a single stage heating/
single stage cooling system. Refer to the following figures for
proper connections to the integrated control module.
