  • Chaos Swing - Electronically controlled louvers and fan speeds creating a more natural, random flow of air, reducing temperature stratification.
  • Inverter - Inverter heat pump air conditioners use a variable speed compressor, rather than the constant speed found in conventional ACs. Instead of shutting off once the desired temperature is reached, the inverter compressor continues to operate at low speed to maintain that temperature. It is quieter to operate and uses less energy than conventional ACs, which cycle on and off.
  • Dehumidifying Mode -  Indoor unit accurately senses room temperature and controls humidity by shutting down the compressor before a room is over-cooled.
