6.3.3.1. Furnace Airflow
Selects the airflow of the furnace when heating.EFFICIENCYis the airflow used
to meet specified ratings,COMFORTis a decreased airflow used to increase the
output air temperature and provide increased comfort.
For the Low heat rise option, set to ON if the system contains a bypass humidifier.
The ON setting will increase the furnace low heat airflow.
