26 , outlet air from compressor is off, the automatic wind from fan motor is low, and wind can be set to high, medium or low by hand. When the indoor temperature is or above 26 , the unit enters the cooling mode and conducts the cooling programme (the preset temperature is 26 ), outlet air from compressor is on and indoor fan motor run in fixed wind speed.
