KMIR545-H219 + 5xKSIE009-H221-I

KSIE009-H221-I | Indoor Unit

Don't let the simple, clean lines of the elegantly-styled KSIE indoor wall-mounted unit fool you. It is jam-packed with high-tech features. With the Follow Feeling function activated, the temperature sensor moves from the wall unit to the remote control. The sensor then directs the mini-split to adjust heating and cooling based on the temperature immediately surrounding anyone carrying the remote.

Also enjoy 12 fan speeds, along with heating, cooling, dedicated dehumidification, turbo function and sleep mode. Auto clean function cleans and dries the evaporator to prevent mildew growth and maintain healthy indoor air quality. The new Home Away freeze protection feature maintains the room at 46º F when you are away for an extended period during the heating season.

The remote control allows for manual operation of the unit when necessary. With the new Quick-Hook Design, the fan coil hangs on the wall easier and faster. An additional gap for pipe installation as well as right to left adjustments add to installation simplicity.

  • 3D air flow technology distributes the air evenly throughout the room. 
  • 24 hour timer and memory function
  • Turbo mode for fast heating & cooling
