- Symbol: Typically represented by a triangle (or circle) with 3 arrows connected, or with the letter A symbol
- Function: Automatically adjusts fan speed, temperature, and humidity
- Usage Time: Suitable for all weather conditions and times of the day.
- Operating Mechanism: Relies on integrated smart temperature sensors. When Auto Mode is activated, the fan in the evaporator will rotate gently for about 1 minute. Then, the air conditioner will automatically adjust the fan to maintain a consistent room temperature.
3.2. Heat Mode - Heating mode
Heat Mode is a heating mode, usually found on two-way air conditioners. It has the effect of heating and is commonly used on cold days.

Besides, when turning on the heating mode, users should note the following issues:
- It is advisable to set the temperature difference from 5 - 10 degrees Celsius compared to the actual outdoor temperature. This helps avoid electricity consumption and does not affect the durability of the equipment
- When turning on Heat mode on cold days, users may experience dry skin, dry throat, or nosebleeds. Therefore, you should use a humidifier or place a water basin in the room to increase humidity.
3.3. Air conditioner mode - Cool mode

- Operating Mechanism: when this mode is activated, the fan and compressor will operate at maximum until the room temperature reaches the set temperature. Then, the condenser will be controlled on/off to maintain the temperature not deviating more than 1 degree Celsius from the set temperature.
3.4. Dehumidification Mode - Dry Mode
In contrast to the other modes, users can also activate the dehumidification mode, also known as Dry mode.

- Usage Time: During rainy days or prolonged humidity in the Northern region, users often turn on the Dry mode to achieve a drier space
- Operating Mechanism: When this mode is activated, the air conditioner will remove moisture from the air. At this point, the fan and compressor operate less, resulting in effective energy savings
When activating this mode, users should not leave it on for too long, only 1 - 2 hours per day is advisable. This prevents dry skin, skin irritation, or dehydration.
