4MXC8 Cassette Indoor Unit Highlights

  • Offers efficiency up to 16.00 SEER.
  • Ceiling mounting for indoor heating and cooling.
  • This ductless cooling and heating system is specially designed with air vents that efficiently reduce operation noise to provide quiet comfort.
  • Turbo function provides temporary high-speed operation to reach your desired temperature quickly.
  • Sleep function automatically adjusts temperature based on set sleeping time to maintain comfort in the room, saving energy.
  • Auto clean function runs the fan when the ductless cooling and heating unit is stopped to prevent bacteria from forming. The unique catechin filter made from natural green tea provides long-lasting sterilization and removes up to 95 percent of potentially harmful bacteria.
  • Timer allows you to set when and how the unit operates.
  • Control your ductless heating and cooling system from anywhere in the room with a wireless remote control (purchased separately). The “I feel” function senses temperature at the remote control instead of at the thermostat.
  • In case of power loss, the ductless heating and cooling system’s memory function will restart the previous operation mode without the need to reset the system.
  • The unit ships with a wired controller displaying temperature, operational mode, and time settings.
