To comply with government mandated efficiency standards, two openings are required for airflows above
1,600 CFM.
Temperature rises in the table are approximate. Actual temperature rises may vary.
Individual cells shaded in gray indicate a temperature rise outside the recommended range.
To comply with government mandated efficiency standards, speed settings which do not have data are not
allowed in HEAT mode.
Data is ACFM (Actual Cubic Feet per Minute)
