WHISPER QUIET Not only are the Stealth systems energy efficient but they are quiet too. Our High-Wall units operate with sound pressure levels starting as low as 26 dB(A). MULTI FAN SPEEDS Whether operating in either Cooling or Heating mode, the indoor fan can be set to your choice of four different speeds (Low, Medium, High or Turbo) to achieve maximum comfort. INTELLIGENT PRE-HEATING The system guards against the annoying cool air blown into the room in heating mode. The system constantly monitors the discharge air temperature. It will delay the indoor fan until the indoor coil has warmed up to prevent blowing uncomfortable cool air into the room. I FEEL MODE The unit will sense room temperature at the remote controller instead of at the indoor unit. It then adjusts airflow and temperature accordingly for the ultimate in personal comfort control and energy savings. ADJUSTABLE AIRFLOW The system has a bi-directional airflow control for maximum comfort. The indoor unit has adjustable vertical swing louvers and can be set in multiple discharge directions from the wireless remote controller. TURBO MODE Use Turbo Mode for situations where you wish to achieve the desired room temperature in the shortest possible time. This mode runs the unit at ultra high speeds for quickest results. FREEZE GUARD Room Freeze Guard protection will automatically keep the room temperature from getting too cold, where water pipes might freeze TIMER MODE The unit can be programmed to turn ON or OFF after a specific amount of time. The time period is adjustable between one half and 24 hours.
