HVAC systems can provide a different air flow rate when the coils are off and the fan continues to operate. These inputs denote the flow rate when the coils are off and constant fan mode operation is selected. If cycling fan mode is used the fan turns off when the coils are off. If the fan operating mode schedule is not entered (blank input) constant fan operating mode is always used and these inputs show the fan flow rate when the coils are off.
When these inputs are autosized the results are a single speed fan that runs at the same cooling or heating speed when constant fan mode is used.
