!WARNING

FIRE OR ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal injury, death, or property damage.

If manual disconnect switch is to be mounted on furnace, select a location where a drill or fastener will not contact electrical or gas components.

NOTE: If modulating dampers are used, blower motor automatically compensates for modulating dampers. If manual disconnect switch is to be mounted on furnace, select a location where a drill or fastener will not contact electrical or gas components.

required, use only a fuse of identical size (3 amp) and type. The furnace control will flash status code 24 when fuse needs replacement.

NOTE: Use AWG No. 18 color-coded copper thermostat wire for lengths up to 100 ft. For wire lengths over 100 ft, use AWG No. 16 wire.

NOTE: For additional thermostat connection diagrams, reference Fig. 52-59.

Accessories

1.Electronic Air Cleaner (EAC)

The furnace control EAC terminals are energized with 115v (1.0-amp maximum) during blower operation. 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 115VAC, 1.0 amps maximum and are energized during blower motor operation. (See Fig. 33.)

NOTE: Low stage airflow may slightly increase the trace amount of ozone created by an electronic air cleaner. Individual sensitivity levels to ozone, along with other operating characteristics of electronic air cleaners may affect the amount noticed by an individual. Refer to the air cleaner manufacturer’s installation instructions for more information regarding ozone and ozone reduction methods available for your air cleaner.

!CAUTION

UNIT DAMAGE HAZARD

Failure to follow this caution may result in unit component damage.

DO NOT connect furnace control HUM terminal to HUM (humidifier) terminal on Thermidistatt, Zone Controller or similar device. See Thermidistatt, Zone Controller, thermostat, or controller manufacturer’s instructions for proper connection.

2.Humidifier (HUM)

Connect an accessory 24 VAC, 0.5 amp maximum humidifier (if used) to the 1/4-in. male quick-connect HUM terminal and COM-24V screw terminal on the control board thermostat strip. The HUM terminal is energized when blower is energized in heating. (See Fig. 33.)
