SYSTE FUNCTIONS
WHISPER QUIET
Not only are the ree 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 uard 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.

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.

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.

TROUBLESHOOTING
PROBLE
System does not restart.
Indoor unit emits unpleasant odor
when started
You hear a“water flowing”sound.
A thin fog or vapor coming out
of the indoor unit when system is
running.
You hear a slight cracking sound
when the system stops or starts.
The system will not run.
The unit is not heating or cooling
adequately.
Water leakage from the
outdoor unit.
CAUSE/SOLUTION
Cause: The system has a built-in three-minute delay to prevent short and/or rapid
cycling of the compressor.
Solution: Wait three minutes for the protection delay to expire.
Cause: Typically unpleasant odors are the result of mold or mildew forming on
the coil surfaces or the air filter.
Solution: Wash indoor air filter in warm water with mild cleaner. If odors persist,
contact a qualified service professional to clean the coil surfaces.
Cause: It is normal for the system to make“water flowing”or“gurgling”sounds
from refrigerant pressures equalizing when the compressor starts and stops
Solution: The noises should discontinue as the refrigerant system equalizes after
two or three minutes.
Cause: It is normal for the system to emit a slight fog or water vapor when
cooling extremely humid warm air.
Solution: The fog or water vapor will disappear as the system cools and
dehumidifies the room space.
Cause: It is normal for the system to make “slight cracking” sounds from parts
expanding and contracting during system starts and stops.
Solution: The noises will discontinue as temperature equalizes after 2 or 3 minutes.
Cause: There are a number of situations that will prevent the system from running.
Solution: Check for the following:
• Circuit breaker is “tripped” or “turned off.”
• Power button of remote is not turned on.
• Batteries in the remote controller are low.
• Remote controller is in sleep mode or timer mode.
• Otherwise, contact a qualified service professional for assistance.
Cause: There are a number of reasons for inadequate cooling or heating.
Solution: Check the following:
• Remove obstructions blocking airflow into the room.
• Clean dirty or blocked air filter that is restricting airflow into the system.
• Seal around door or windows to prevent air infiltration into the room.
• Relocate or remove heat sources from the room.
Cause: It is normal for the outdoor unit to generate condensate water in the
reverse cycle heating and defrost mode.
Solution: This is normal. No action is required.

CAUTION
TROUBLESHOOTING
PROBLE
Water leaking from the indoor
unit into the room.
Wireless remote controller
does not work.
The unit will not deliver air.
Moisture or condensation
on the discharge air louvers
or outlet vents.
CAUSE/SOLUTION
Cause: While it is normal for the system to generate condensate water in cooling
mode, it is designed to drain this water via a condensate drain system to a safe location.
Solution: If water is leaking into the room, it may indicate one of the following.
• The indoor unit is not level right to left. Level indoor unit.
• The condensate drain pipe is restricted or plugged. All restrictions must
be removed to allow continuous drainage by gravity.
• If problem persists, contact a qualified service professional for assistance.
Cause: There are a number of possible reasons
Solution: Check the following:
• The batteries might be low. Change the batteries.
• The remote controller must be within 25 ft. (7.5 m) with no obstructions
of the indoor unit. If remote controller needs to be replaced, contact a
qualified service professional for assistance. In the meantime, use the
Aux Button to operate the system.
Cause: There are a number of system functions that will prevent air flow.
Solution: Check for the following:
• In heating mode, the indoor fan may not start for three minutes if the
room temperature is very low. This is to prevent blowing cold air.
• In heat mode, if the outdoor temperature is low and humidity is high,
the system may need to defrost for up to 10 minutes before beginning
a heating cycle.
• In dry mode, the indoor fan may stop for up to three minutes during the
compressor off delay.
• Otherwise, you should contact a qualified service professional for assistance.
Cause: It is normal for the system to develop condensation or moisture on the
discharge air louvers when cooling warm humid air for a long period of time.
Solution: The condensation or moisture will disappear as the system cools and
dehumidifies the room space.
S top operation and call for service in the following circumstances:
• You hear a harsh or unusual sound during operation.
• Unusually foul odor is emitted during operation.
• Water is leaking in the room.
• You notice a burning smell or see smoke.
• Circuit breaker trips frequently, or unit stops abnormally often.
