The heating capacity based on 68ºF DB entering air.
Entering air correction factors table is used to correct the catalog values if the desired EAT is outside of rated EAT. Calculate de-
sired EAT based on the "EAT Wet Bulb" and EAT Dry Bulbcolumns. Multiply the catalog results by the value corresponding to
the design EAT and the desired output.
