System Functions - Gree Multi21 Series Owner's Manual

SYSTEM FUNCTIONS

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.
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.
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 Mini-Floor Console 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.
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.
