AHRI/ISO/ASHRAE 13256-1 uses entering air conditions of Cooling - 80.6°F DB/66.2°F WB,
and Heating - 68°F DB/59°F WB entering air temperature
ClimaDry II Option Notes:
Unit minimum entering air temperature when in dehumidication or cooling mode is 65°F DB.
Operation below this minimum may result in nuisance faults.
