dehumidification mode for 30 minutes, then the machine start defrost, the icon
compressor stop working and fan motor operate under high speed. When the sensor detects
the temperature of evaporator≥2℃ and the defrost time ≥10 minutes, the auto-defrost mode
end and the compressor start to work, the machine began to dehumidify, the icon
off. When the machine start the defrost function, during the 30 minutes of continuously
dehumidification, work process, when the sensor detects the temperature of evaporator≥0℃
and lasts 2 minutes, then the defrost function will be cancelled. If in this 30 minutes, the
sensor detects the temperature of evaporator≥0℃,while within continuous 2 minutes, the
sensor detects the temperature of evaporator≤-1℃,then the defrost mode is still valid, then
the machine will start to auto defrost after 30 minutes of continuously dehumidification.
8. Compressor protection function
During the operation, any malfunction forced compressor failed, resulting compressor
shut off, it takes 3 minutes to rework for protection purpose.
When compressor stops working, if immediately restart, cooling system pressure is not
balanced, easy to lead for overload, so the machine is equipped with the compressor delay
3 minutes to re-start function.
9. High/Low temperature protection function
When the sensor detects the ambient temperature ≤0℃ or ≥40℃,the machine will
stop working and the digital tube will show C2 and flashing.The fan motor will continue to
work at previous setted speed for 3 minutes,then stop.
When NTC detect the evaporator's temperature ≥ 40 ℃ and last 2 minutes,the
machine will stop working and the digital tube will show C1 and flashing.
When power off,then restart the machine, if the ambient temperature＞0℃ or ＜
40 ℃ ,the machine come back to dehumidify normally.(It takes 3 minutes from the
compressor stop to it come back to work for compressor protection purpose.)
