Orient air conditioner series owns unique rotary air vane technology. In cooling mode, air vane is opened counter clockwise. Cool air blows out horizontally and then falls down by gravitation. Thus room temperature is quickly and evenly achieved. Without decreasing the flow volume, the large diameter cross flow fan can greatly reduce the indoor units noise by lowering fan speed. It can maintain the most comfortable temperature and save energy. The turbo mode helps in achieving lowest temperatures in minimum time. When the power is off and then it gets on again the unit automatically restores the previous function settings.
