[ In Square Feet ]
For the controller to properly calculate the Return Air CFM, you need
to enter the area in square feet of the Return Air duct/damper. When
measuring the Return Air duct damper area, be sure to measure the
inside dimensions of the damper. The duct size needs to be accurate
to two decimal places. The more accurate the measurements, the
more accurate the CFM reading will be. Default is 0.
