The 24-v circuit contains an automotive-type, 3-amp. fuse located on the
control. Any direct shorts during installation, service, or maintenance
could cause this fuse to blow. If fuse replacement is required, use ONLY
a 3-amp. fuse of identical size.

ACCESSORIES

1. Electronic Air Cleaner (EAC)
Connect an accessory Electronic Air Cleaner (if used) using 1/4-in
female quick connect terminals to the two male 1/4-in
quick-connect terminals on the control board marked EAC-1 and
EAC-2. The terminals are rated for 115 VAC, 1.0 amps maximum
and are energized during blower motor operation (see
2. Humidifier (HUM)

board thermostat strip. The 24VAC HUM terminal is energized
when there is a call for heat (W) and the pressure switch (PRS)
closes (see Fig. 28
b. HUM: Connect an accessory 115VAC (EAC and HUM are 1
amp maximum combined) humidifier (if used) to the ¼-inch
male quick connect HUM terminal and EAC-2 ¼-inch quick
connect. The HUM terminal is energized when the inducer
motor is energized (IDR) (see
NOTE: A field-supplied, 115-v controlled relay connected to EAC
terminals may be added if humidifier operation is desired during blower
operation.
