B. Description of Parameter Item 06, 07, 08 and 09 (Conventional defrosting)
Conventional defrosting: when the EA temperature lower than the setting defrost temperature (the
preset value is 1℃) and lasts for 1 minute, and it has been exceed the defrosting interval (the preset
value is 30 minutes), the supply fan will stop and exhaust fan run at high speed, until the EA tempera-
ture is +15℃ and lasts for 1 minute, or the defrosting has been lasting for a certain time (i.e. defrost-
ing duration, whose preset value is 10 minutes), then the ventilator will turn back to the original op-
eration state.
C. Description of Parameter Item 10 and 11 (CO2 sensor function)
When the ventilator is in stand by condition or any speeds that are not the highest speed, if CO2 sen-
sor detects that the CO2 concentration is higher than the setting value for more than 5 seconds, the
ventilator will start up automatically and run at high speed. Only when the CO2 concentration is lower
than the setting value for more than 5 seconds. Ventilator will return to previous condition.
D. Description of Parameter Item 12 and 13 (Humidity sensor function)
When the ventilator is in stand by condition or any speeds that are not the highest speed, if humidity
sensor detects that the humidity concentration is higher than the setting value for more than 5 sec-
onds, the ventilator will start up automatically and run at high speed. Only when the humidity concen-
tration is lower than the setting value for more than 5 seconds. Ventilator will return to previous condi-

A. Description of Parameter Item 02, 03 and 04 (automatic bypass function)
refer to the parameter list number 3 and number 4, if the fresh air temperature within the X and X+Y,
then bypass open, if fresh air temperature lower than X, or higher than X+Y, then bypass closed, i.e. by
setting X=19, Y=3, then when fresh air between 19 and 22 celsius, bypass open, when fresh air lower
