Multi-zone Free Match



  • M2OF, M3OF, M4OF, M5OF multi-zone ductless outdoor unit works with up to five indoor systems. Each indoor system comes with its own control, so you can set each room to a different temperature. Free match with any wall mount, ceiling cassette, duct system or console. DC INVERTER HEAT PUMP provides year round comfort allowing unit to reverse refrigerant process in cold weather, by extracting outside heat and transferring inside.

Excellent for house additions without forced air heating systems or where ductwork is not possible.

  • Turbo Operation: unit maximizes cooling or heating output capacity to attain desired temperature in the shortest amount of time
  • Anti-Cold-Air
  • Prevents cold air from blowing out at the beginning of operation by automatically regulating fan speed according to temperature
  • Sleep Mode
  • Unit automatically increases (cooling) or decreases (heating) 2°F/hour for first 2 hours, and holds steady for next 5 hours before switching off and returning to preset temperature for both energy savings and comfort
  • Hydrophilic Aluminum Fin
  • – Improves indoor unit cooling efficiency by enabling unrestricted flow of condensate water between aluminum fins
    – Improves outdoor unit heating efficiency by accelerating defrosting process
