Parameters introduction
Number 00– range 0 or 1, 0 means power to auto restart function is not available, 1 means power to
auto restart function is ON.
Number 01– this function is not available now.
Number 02 and 03– number 02 range from 5C to 30C, default value 19C is bypass open temperature X,
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
lower than –1C, then ventilator enter the auto defrosting mode.
Number 06– range from 2 to 20 minutes, default value 10 minutes, this means defrosting duration time
is 10 minutes.
Number 07– CO2 sensor function value, this value is to allow the ventilator automatically change to high
speed when CO2 contraction is higher than setting value.
