CODE
NORMAL OPERATION CODES
CODE AT DUAL 7-SEGMENT DISPLAY OF IFC: 0
0
DESCRIPTION: This code is displayed anytime there is no fault code to display and no thermostat call present. The
furnace is idle.
CODE AT DUAL 7-SEGMENT DISPLAY OF IFC: H or h (steady on - not blinking)
DESCRIPTION: This code is displayed any time there is a call for gas heat. The lower-case "h" is displayed when the
furnace is calibrating. Calibration will occur during the first heat call after power reset or power-up. The calibration cycle
H or h
allows the blower to be adjusted to deliver the proper airflow amount for a given heat rise at a given rate. Calibration
(steady)
takes more five minutes at a reduced input. Calibration will not occur if the SA sensor is not connected. If either (upper
case "H" or lower-case "h" is blinking, it is an indication that a "V" signal is not present on a system that is non-
communicating. Blinking of this code will not be considered a fault if the thermostat chosen for use is non-
communicating and non-modulating. See fault codes "H" (blinking) and "h" (blinking) for more information.
C
CODE AT DUAL 7-SEGMENT DISPLAY OF IFC: C
DESCRIPTION: This code indicates the furnade is in cooling mode (any stage).
HP
CODE AT DUAL 7-SEGMENT DISPLAY OF IFC: HP or hP
DESCRIPTION: This code indicates the furnade is in heat-pump heating mode (dual-fuel systems only) (any stage).
F
CODE AT DUAL 7-SEGMENT DISPLAY OF IFC: F
DESCRIPTION: The furnace is in continous fan mode.
CODE AT DUAL 7-SEGMENT DISPLAY OF IFC: dF
dF
DESCRIPTION: This code indicates that the heat-pump is in deFrost mode (dual-fuel systems only) and furnace is
operating as supplemental heat at a fixed 65% of maximum gas heating capacity.
CODE AT DUAL 7-SEGMENT DISPLAY OF IFC: Cd
Cd
DESCRIPTION: This code indicates that cooling is active with dehumidification active at the same time. When
dehumidification is active, the cooling airflow will be reduced in order to allow water to accumulate on the condenser
thereby removing humidity from the conditioned environment.
