Frequently Asked Questions

What is Voice Control/Hello Lisa?

"Hello Lisa" is a voice control feature that lets you turn on or control your AUX air conditioner by simply saying "Hello Lisa" followed by a command, like adjusting the temperature or mode. It works without needing a remote, app, or internet connection, making it super easy and convenient to use hands-free.

How do I enable or disable the Voice Control Function Mode (referred to as "Hello Lisa")
  1. Switch the air conditioner to Dehumidification Mode.
  2. Set the temperature to 60 degrees Fahrenheit (or 16 degrees Celsius, depending on your unit's default scale).
  3. Press the "-" (minus) button on the remote control eight times in succession.

This sequence will toggle the voice control feature on or off. If the process does not yield the expected result, consult your model's user manual or contact AUX customer support for verification.

How do I connect the Wi-Fi function?

To connect your AUX mini-split to Wi-Fi, please check the Wi-Fi setup manual included with your indoor unit. To connect your AUX mini-split to Wi-Fi:

  • Find the Wi-Fi setup manual with your indoor unit.
  • Download the "AC Freedom" app on your phone (iOS/Android).
  • Follow the app's setup wizard to connect to a 2.4GHz Wi-Fi network.
How can I switch from Celsius to Fahrenheit and back?

To switch the display temperature between Celsius and Fahrenheit on your AUX air conditioner, press and hold the "+" (plus) and "-" (minus) buttons on the remote control at the same time for 3 seconds. The display should toggle between Celsius and Fahrenheit. Repeat the process to switch back.

What's "SOFT" mode?

The "SOFT" mode on your AUX air conditioner runs the unit at a lower fan speed to create a quiet, gentle airflow. This mode ensures comfortable cooling with minimal noise, making it ideal for relaxing or sleeping.

What's the "I-FEEL" feature?

The "I-FEEL" feature on your AUX air conditioner uses a temperature sensor in the remote control to monitor the temperature at your location in the room. It adjusts the air conditioner's cooling or heating to maintain your desired comfort level based on where you are, rather than the unit's location.

How does "Self-Cleaning" work?

The "Self-cleaning" feature on your AUX air conditioner cleans the indoor and outdoor unit's coil in three steps:

  • Freezing: The unit cools to freeze moisture on the coil.
  • Melting: It heats up to melt the ice, washing away dirt.
  • Drying: The fan runs to dry the coil completely.

The process takes about 30 minutes, leaving your AC clean and ready to use. Activate it using the "Self-Clean" button on your remote. Check your user manual for model-specific instructions.

How often should I clean my filter?

You should clean your AUX air conditioner's filter every 4 to 6 weeks to keep it running efficiently. If you use the AC heavily or live in a dusty area, clean it more often, like every 2 to 3 weeks
