DEHUMIDIFICATION MODE
CODE AT DUAL 7-SEGMENT DISPLAY OF IFC: 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

DEFROST MODE
CODE AT DUAL 7-SEGMENT DISPLAY OF IFC: dF
DESCRIPTION
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
allows the blower to be adjusted to deliver the proper airflow amount for a given heat rise at a given rate. Calibration
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.
