The furnace integrated control module is equipped with
line voltage accessory terminals for controlling power to
an optional eld-supplied humidier and/or electronic air
cleaner.
Turn OFF power to the furnace before installing any
accessories. Follow the humidier or air cleaner
manufacturers’ instructions for locating, mounting,
grounding, and controlling these accessories. Accessory
wiring connections are to be made through the 1/4” quick
connect terminals provided on the furnace integrated
control module. The humidier hot terminal is identied
as 120V HUM-H, its neutral terminal is identied as 120V
HUM-N. The electronic air cleaner hot terminal is identied
as EAC-H, its neutral terminal is identied as 120V
EAC-N. All eld wiring must conform to applicable codes.
Connections should be made as shown. (See Figure 32)
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 humidier terminal 120V
HUM-H is energized with 115 volts whenever the induced
draft blower is energized. This terminal can also be used
to provide 115 volt power to a humidier transformer. The
remaining primary transformer wire would be connected
to the Line N on the control board. The integrated control
module electronic air cleaner terminals EAC-H is energized
with 115 volts whenever the circulator blower is energized.
