SYSTE 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).
ULTI 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 ODE
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 ODE
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
TI ER ODE
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.

SYSTE FUNCTIONS
ODE BUTTON
The unit can be set to five different operating modes: H AT, COOL, DRY, FAN ONLY and AUTO.
NOTE: AUTO MOD has fixed setpoints of 68° F heating and 78° F cooling, which are
not adjustable. The system will automatically select heating or cooling to maintain room
temperature within this band.
SLEEP ODE
The Vireo offers three selectable sleep modes for your comfort. The unit will automatically
adjust room temperature during your sleep time. This slight change in temperature will not
affect your comfort level due to the natural effects that sleeping has on the body, but it will
save on energy consumption and will lower electric bills.
ENERGY SAVINGS ODE
This feature will automatically select the optimal compressor and fan speeds to allow for
energy savings while operating in Cooling or Heating modes. The compressor and fan will
automatically slow down as the room temperature reaches the set point.
SELF-DIAGNOSIS
Vireo has a built-in computer which uses real-time diagnostics which help prolong the unit’s
life. The automatic diagnosis feature continuously scans for errors or malfunctions and fault
codes are shown on the unit display to facilitate troubleshooting and repair.
POWER FAILURE ODE
Power interruptions are no problem for the Vireo system. User selections and system parameters
are stored in non-volatile memory. These parameters are retained during a power failure. When
power is returned, the Vireo system will automatically return to the last operating mode.

SYSTE FUNCTIONS
INTELLIGENT DEFROST
The Vireo Intelligent Defrost function increases room comfort and saves energy by eliminating
unnecessary defrost cycles. In heating mode, the unit will monitor the outdoor coil for frost build
up. Once frost buildup has been detected, the system will switch into a defrost mode to remove
the frost.
POLY ERIC AIR FILTER
The polymeric mesh filters save energy by preventing the indoor coils from being plugged with
dirt and lint. This economical and sturdy filter may be washed, vacuumed and reused.
FAHRENHEIT °F/CELSIUS °C
The remote controller and indoor wall unit front panel can be set to display in either °F or °C.
PRIVACY LOCK ODE
The wireless remote controller has a Lock feature. The Lock averts unauthorized access or
tampering with system settings.
AGENCY LISTINGS
All systems are listed with AHRI (Air conditioning, Heating, and Refrigeration Institute) and
are TL certified per UL Standards.
