Percent of High Cooling
Airflow
Note 1: Minimum Outdoor Unit Cooling Stage as a percentage of High Cooling Airflow (value is rounded up to the closest number on
25 CFM resolution.
Note 2: Minimum Outdoor Unit Heating Stage as a percentage of High Heat Pump Airflow (value is rounded up to the closest number
on 25 CFM resolution).
Note 3: All communicating Installer Parameters default CFM values based on DIP switch setting (non−communicating value) are cal-
culated using the CFM conversion tables and rounded up to closest number on 25 CFM resolution.
Note 4: Parameter dependency − Certain parameters are dependent on others and may not be shown on the display.
Note 5: Default Values − Jumper/DIP switches impact the default value of some parameters.
