SYSTE FUNCTIONS
WHISPER QUIET
Not only are the systems energy efficient but they are quiet too. Floor/Ceiling operates
with sound levels starting as low as 36 dB(A).
ULTI FAN SPEEDS
Whether operating in either Cooling or eating mode, the indoor fan can be set to your choice of
three different speeds (Low, Medium or igh) to achieve maximum comfort.
INTELLIGENT PRE-HEATING
Stealth 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 RE OTE
The multi-functional infrared hand held wireless controller is sleek, ergonomically
designed, easy to use and has a large backlit LCD display.
TETHER CONTROLLER
The 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.
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 ODE
The unit will sense room temperature at the remote controller instead of at the indoor unit during
Cooling Mode. 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.

SYSTE FUNCTIONS
SWING LOUVER
The adjustable swing louvers can be controlled from the wireless controller. Swing louvers allow
nine 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 ODE
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 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.
CLOCK
The wireless remote controller has a built-in clock feature. The remote will display the time of day
in a 24-hour format.
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.
ODE BUTTON
The unit can be set to five different operating modes: EAT, 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 ODE
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.
6

SYSTE FUNCTIONS
X-FAN ODE
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 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 ODE
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 A RI (Air conditioning, eating, and Refrigeration Institute) and are
ETL certified per UL Standards.
