Fault Code 23

INVALID BLOWER AIRFLOW SELECTIONÐThis fault indicates improper A/C or CF switch setting. The -14 units can deliver sufficient airflow for 1-1/2 to 3-1/2 tons A/C and 600 to 1400 CFM for continuous fan. The -20 unit can deliver sufficient airflow for 2 to 5 tons A/C and 800 to 2000 CFM for continuous fan. If fault code is flashing, unit still operates, but it defaults to closest allowable airflow.

NOTE: Boards with date codes of 9506 or later will flash fault code and set continuous fan airflow to same airflow as A/C if continuous fan is adjusted to a higher airflow than A/C setting.
