SYSTEM FUNCTIONS

WHISPER QUIET

Not only are the Gree systems energy efficient but they are quiet too. Vireo 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 Vireo 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 Vireo 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.
