Number 03 range from 2C to 15C, default value 3C is the auto bypass open temperature Y, when OA
temperature is less than X or higher than X+Y, then bypass off, when OA temperature is between X and
X+Y, then bypass on.
Number 04– range from 15 to 99 minutes, default value 30 means the defrosting interval time is 30
minutes.
Number 05– range from –9C to 5C, default value –1C means in Winter when exhaust air temperature
