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.
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.
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.
SELF-DIAGNOSIS
With an on-board computer using real-time diagnostics, the Gree U-Match 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.
AGENCY LISTINGS
All systems are listed with AHRI (Air conditioning, Heating, and Refrigeration Institute) and
