The mode button on the Gree AC remote control is the key to selecting the operating mode. This button allows you to cycle through the different modes, including HEAT, COOL, DRY, FAN ONLY, and AUTO. Familiarize yourself with the location and function of the mode button on your remote control.

Setting the AC to Auto Mode

To set your Gree AC to the auto mode, follow these steps:

  1. Locate the mode button: Identify the mode button on your Gree AC remote control. This button is typically labeled with the “MODE” text or a symbol representing the different operating modes.

  2. Press the mode button: Press the mode button repeatedly until the display on the remote control shows the “AUTO” indicator. This indicates that the air conditioner is now in the auto mode.

  3. Confirm the auto mode: Verify that the auto mode is successfully engaged by checking the display on the indoor unit of your Gree AC. The display should also show the “AUTO” indicator, confirming that the system is in the auto mode.

Understanding Fixed Setpoints in Auto Mode

It’s important to note that in the auto mode, Gree ACs have fixed setpoints for heating and cooling. These setpoints are not adjustable by the user and are set at 68°F (20°C) for heating and 78°F (25.5°C) for cooling.

The Gree AC system will automatically select the appropriate mode (heating or cooling) to maintain the room temperature within this predefined temperature range. This feature ensures optimal comfort and energy efficiency, as the system will automatically adjust its operation based on the current room conditions.

Additional Features in Auto Mode

Gree ACs offer several additional features that can be utilized in the auto mode to enhance your comfort and energy savings. These features include:

  1. Sleep Mode: The sleep mode function gradually adjusts the temperature setpoint to provide a more comfortable sleeping environment. This feature can be activated using the remote control while the AC is in the auto mode.

  2. Energy Savings Mode: The energy savings mode optimizes the AC’s operation to minimize energy consumption without compromising comfort. This mode can be enabled through the remote control while the system is in the auto mode.

  3. Intelligent Defrost: Gree ACs are equipped with an intelligent defrost system that automatically detects and removes frost buildup on the outdoor unit’s heat exchanger. This feature ensures efficient operation and maintains optimal heating performance, even in cold weather conditions.

To activate these additional features, refer to the user manual or consult the Gree AC remote control instructions for the specific steps to enable them while the system is in the auto mode.

Troubleshooting and Maintenance

If you encounter any issues or have questions regarding the auto mode operation of your Gree AC, refer to the manufacturer’s user manual or contact Gree’s customer support for assistance. Regular maintenance, such as cleaning the air filters and outdoor unit, can also help ensure optimal performance of your Gree AC in the auto mode.


By following the steps outlined in this comprehensive guide, you can easily set your Gree AC to the auto mode and take advantage of its advanced features. Remember to familiarize yourself with the remote control, understand the fixed setpoints, and explore the additional energy-saving and comfort-enhancing functions available in the auto mode. With this knowledge, you can enjoy a comfortable and efficient indoor environment with your Gree air conditioner.
