NOMENCLATURE

Superior Design for Superior Performance

Gree’s discreet Multi21 Floor/Ceiling provides low-noise performance through design
and innovation. The Floor/Ceiling is a one-stop solution for heating and air conditioning
large and small rooms. This flexible climate solution conveniently disappears above the
surface of any room’s drop ceiling. Features include a highly effective inverter driven
variable speed compressor, 4-way air discharge, multi speed fan, swing louver
and a cleanable air filter.

Gree’s cutting edge fan technology is quiet and powerful. It efficiently circulates the
conditioned air throughout the space while safely removing water via the internal
condensate drain pump.

Flexibility and innovation make the Floor/Ceiling the best choice for creating ideal
climate conditions.

electric shock or damage to unit.

• In the event of a failure (burning smell, etc.), immediately disconnect all electrical
power to indoor and outdoor units.

SAFETY PRECAUTIONS

Please read the following before operation.

Recognize safety information. This is the safety-alert symbol. When you see this symbol on
the unit and in instructions or manuals, be alert to the potential for personal injury. Understand
these signal words: DANGER, WARNING, and CAUTION. These words are used with the
safety-alert symbol.

DANGER identifies the most serious hazards which will result in severe personal injury or death.

WARNING signifies hazards which could result in personal injury or death.

CAUTION is used to identify unsafe practices which may result in minor personal injury or

product and property damage.

NOTE is used to highlight suggestions which will result in enhanced installation, reliability, or operation.

NOTE: Your actual air conditioning & heating system and related devices may differ from

the images shown in this manual.

This appliance is not intended for use by children without responsible adult supervision.
Proper care should be taken to ensure safety.

Heat pumps, air conditioners & heating equipment should be installed, started up, and
serviced only by qualified installers and service technicians. Air conditioning, heat pumps
and refrigeration systems are hazardous due to high voltage electrical components, high
refrigerant pressures, and moving parts.

SYSTEM FUNCTIONS

WHISPER QUIET

Not only are the Gree systems energy efficient but they are quiet too. Floor/Ceiling operates
with sound levels starting as low as 37 dB(A).

MULTI FAN SPEEDS

Whether operating in either Cooling or Heating mode, the indoor fan can be set to your choice
of three different speeds (Low, Medium or High) to achieve maximum comfort.

BUILT IN CONDENSATE LIFT PUMP

The unit features a built-in drain pump that lifts condensate up to 39 inches above the drain
pan to a gravity condensate drain system. In most cases, the internal condensate lift mechanism
will avoid the need for an external condensate pump.

CONDENSATE SENTRY

The unit’s fail-safe mechanism recognizes when there is a high level in the condensate pan and
shuts off the system to prevent overflow.

INTELLIGENT PRE-HEATING

Multi21 Systems guard 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.

CONTROLLERS

The Floor/Ceiling unit comes with a factory supplied Wireless Remote Controller and a Wired
Tether Controller.

WIRELESS REMOTE

The Gree multi-functional infrared hand held wireless controller is sleek, ergonomically
designed, easy to use and has a large backlit LCD display.

TETHER CONTROLLER

The Gree wired Tether Controller mounts to the wall up to 26 feet from the unit.
It provides complete control over your unit’s operation mode, desired temperature,
fan speed, airflow direction and more.

5

SYSTEM FUNCTIONS

INTELLIGENT DEFROST

The 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
buildup. Once frost buildup has been detected, the system will switch into a defrost mode to
remove the frost.

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. This function is only available with the wired Tether Controller.

SWING LOUVER

The adjustable swing louvers can be controlled from the wireless controller. Vertical swing
louvers allows five different air discharge directions including Continuous Sweep. Maximize
comfort by adjusting the direction of airflow in the room by moving the louvers up or down.

POWER FAILURE MODE

Power interruptions are no problem for the

Multi21

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 Floor/Ceiling system will automatically return to the last operating mode.

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.

CLOCK

The wireless remote controller has a built-in clock feature. The remote will display the time of
day in a 24-hour format.

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.

6

SYSTEM FUNCTIONS

MODE BUTTON

The unit can be set to five different operating modes: HEAT, COOL, DRY, FAN ONLY and AUTO.

NOTE: AUTO MODE has fixed setpoints of 68° F heating and 77° F cooling, which are
not adjustable. The system will automatically select heating or cooling to maintain room
temperature within this band.

SLEEP MODE

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.

X-FAN MODE

When operating in humid areas, the X-fan or Dry Coil function allows the indoor fan to run for
a pre-determined amount of time after the unit is turned off (cooling or dry modes) to ensure
that additional moisture is removed from coil.

FAHRENHEIT °F / CELSIUS °C

The remote controller can be set to display in either °F or °C.

SELF-DIAGNOSIS

With an on-board computer using real-time diagnostics, the Gree Multi21 system helps to
prolong its own life. The automatic diagnosis feature continuously scans for unacceptable
operating conditions or malfunctions. If such conditions occur, the system takes corrective action
or stops. Error codes are shown on the unit display to facilitate easy troubleshooting and repair.

PRIVACY LOCK MODE

The wireless remote controller has a Privacy Lock. The Privacy 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
ETL certified per UL Standards.

REMOTE CONTROLLER OPERATIONS

The wireless remote controller is sleek, versatile and allows you to change room temperatures
and functions on your Multi21 Floor/Ceiling system from the palm of your hand. The large
LCD display and buttons make it easy-to-understand and easy-to-use.

The remote controller is set from factory to display temperatures in °F. If °C is desired, turn

the remote controller

OFF

with the

ON/OFF

button and then press “MODE“ and “ ” buttons

on the remote simultaneously for 5 seconds.

ON/OFF BUTTON

When the system is in OFF mode, the remote controller will
display the time and last room setpoint. When you press the
ON/OFF button, this indicator will be displayed and the
unit will start in the last operating mode and room setpoint.

NOTE: If the ON/OFF button is pressed too soon after a
stop, the compressor will not start for 1 to 5 min. due to the
inherent protection against frequent compressor cycling.
