Gree Livo Air Conditioner Remote Buttons and Functions Guide

Thank you for choosing a Livo GEN3 (LIVV) Heat Pump System! You can feel confident in your selection because the same pride in craftsmanship and engineering knowledge that goes into millions of other GREE-installed products worldwide has gone into your unit. Please read this owner’s manual carefully before operation and retain it for future reference.

INTRODUCTION

Superior Design for Superior Performance
GREE Inverter-driven, Mini Split Heat Pumps are beautifully designed to deliver effective cooling or heating while fitting unobtrusively into any decor. The indoor unit’s aesthetically pleasing, minimalist design blends nicely in any home or office. Your unit offers quiet, energy-efficient comfort, powered by GREE’s famous G10 Inverter technology. To speed up the process of bringing conditioned air exactly where you want it, the unit features vertical airflow control. Customizable mode controls allow you to adjust fan speeds, select sleep-time settings, and more, all through the easy- to-use wireless remote controller, or an optional Wired Controller. There are Turbo mode, I-FEEL function, WiFi connectivity, and other advanced features to make your system even more versatile, for year-round comfort and energy savings.

Front Panel Display
The front panel on the indoor unit contains system status lights and an easy- to-read LED display.

this manual.

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

WARNING
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.

WARNING

• Disconnect electrical power to the indoor and outdoor units before performing any maintenance or cleaning.
• Do not attempt to repair the GREE system yourself. Incorrect repairs may cause electric shock or fire.
• Contact a qualified service technician for all service requirements.

SYSTEM FUNCTIONS

WHISPER QUIET
Not only are the GREE systems energy efficient but they are quiet too. LIVV High-Wall units operate with sound pressure levels starting as low as 26 dB(A).

MULTI FAN SPEEDS
Whether operating in either Cooling or Heating mode, the indoor fan can be set to your choice of four different fan speeds (low, medium, high, and turbo) to achieve maximum comfort.

INTELLIGENT PREHEATING
The LIVV 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 FUNCTION
The unit will sense room temperature at the remote controller instead of at the indoor unit. It then adjusts airflow and temperature accordingly for ultimate personal comfort.

ADJUSTABLE AIRFLOW
The LIVV system has a bi-directional airflow control for maximum comfort. The indoor unit has adjustable vertical and horizontal swing louvers and can be set in multiple discharge directions from the wireless remote controller.

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 the quickest results

VACATION MODE (FREEZE GUARD)
Vacation mode (freeze guard) sets the unit to 46°F (8°C) in heating to keep the temperature in the space above freezing.

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 is not adjustable. The system will automatically select heating or cooling to maintain room temperature within this band.

SLEEP MODE
The LIVV offers a Sleep Mode function for your comfort. The unit will automatically adjust the 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 MODE
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.

SELF-DIAGNOSIS
Your LIVV has a built-in computer that uses real-time diagnostics which help prolong the unit’s 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 MODE
Power interruptions are no problem for the LIVV 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 3VIR system will automatically return to the last operating mode.

INTELLIGENT DEFROST
The LIVV 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 build-up. Once frost buildup has been detected, the system will switch to defrost mode to remove the frost.

WASHABLE POLYMERIC AIR FILTER
The polymeric mesh filters save energy by preventing the indoor coils from being plugged with dirt and lint. This economical and sturdy filter may be washed, vacuumed, and reused.

FAHRENHEIT / CELSIUS
The remote controller and indoor wall unit front panel can be set to display at either °F or °C.

REMOTE LOCK-OUT
The wireless remote controller has a Lock feature. The Lock averts unauthorized access or tampering with the system settings.

AGENCY LISTINGS
All systems are listed with AHRI (Air Conditioning, Heating, and Refrigeration Institute) and are ETL certified per UL Standards.

• There’s an abnormal sound during the operation.
• The circuit breaker trips off frequently.
• The air conditioner gives off a burning smell.
• The indoor unit is leaking.
• Do not try to service or repair the unit yourself.
• If the unit operates abnormally it may cause internal or external damage, electric shock or become a fire hazard

ENERGY SAVING TIPS

1. Reduce room setpoint at night: During the night hours, you don’t require the same level of conscious cooling or heating. Try using Sleep Mode to gradually relax room temperature and allow the unit to run less and save energy.
2. Curtains and shades: In the summer, it is recommended to block the effects of the sun. Close window curtains and shades on the south and west side of your home to help block solar heat. In winter, the sun is your friend. Open curtains and shades to allow solar heat into your room.
3. Close doors: If you don’t need to heat and cool your whole home, confine the heating and cooling to one room by closing doors.
4. Service the unit: Some basic maintenance might be all you need. The outdoor unit will greatly benefit from a good hosing off, leaves, grass clippings, and other debris can stick to coil fins and make the unit work up to 15% harder!
5. Rearrange the room: Furniture that obstructs the airflow, needs to be removed or rearranged accordingly.
6. Try 75 degrees: 75°F is a good point for an air conditioner to run at its optimal performance level. Even a 5-degree change in temperature can make your unit use up to 40% more energy.
7. Lighting: Turning lights off can help reduce your heat. Each light bulb is a tiny heater. Your air conditioner must waste energy overcoming the heat from your lights to reach and hold your desired room temperature.
8. Zero occupancy: During zero occupancy turn your unit to Auto mode and make sure windows and curtains are closed. Although the room temperature may be less than optimal for a few minutes when you return, the unit will soon have the room back to your desired temperature.
9. Don’t forget the fan: The fan is much like a car. The faster it runs, the more energy it uses. Try saving money by using the comfortable quiet low fan speed as much as possible
