Controlling your LG Wi-Fi AC is easier than searching for the remote every time you want to change the temperature or mode. With the LG ThinQ App, you can connect your air conditioner to your smartphone and manage settings like cooling mode, fan speed, temperature, and schedules directly from your phone.

In this guide, we’ll walk you through how to set up the LG ThinQ App and use it to control your LG Wi-Fi AC without needing the physical remote.

Before you start: Your LG Wi-Fi AC must already be connected to the LG ThinQ app. If you haven't completed the setup yet, follow our guide on how to connect your LG 5 Star Wi-Fi AC to the LG ThinQ app before continuing.

Control Your LG Wi-Fi AC From the LG ThinQ App (Android/iOS)

Once your LG AC is linked with the ThinQ App, using it becomes simple. You can turn the AC on or off, change the temperature, adjust the fan speed, and switch between different modes right from your phone. Let’s look at how you can control these features through the app.

1. Increase or Decrease the Cooling Temperature

Here's a step-by-step guide to control your LG AC's temperature with the LG ThinQ app. Just follow the steps as listed below. Make sure your smartphone and the LG AC must be connected to internet. You don't need to connect your smartphone to the same Wi-Fi to which your AC is connected. For your smartphone, you can also use its cellular mobile data to send remote control commands to your AC.

1. Open the LG ThinQ smart home app and tap the 'Device' tab. You will see all your LG ACs listed here. Tap the 'Power' button to turn on the AC as this will enable all the functions.

2. Once you tap the 'Power' button, your AC will start running and the app will show details such as the indoor temperature and target temperature. Tap the AC card/widget to open its functions.
3. Once you tap the AC card, you will see the controls on the screen as shown in the image below. From this software control panel you can control your AC's temperature, indoor unit's fan speed, airflow swing (if applicable), make it convertible (40%, 60%, 80% or set to AI Plus convertible). You will also see options for 'VIRAAT' mode or 'Jet Mode' and 'Himclean' (for cleaning heat exchanger) here.

4. To increase or decrease the AC temperature, see the the temperature control function just below the 'Power' button. Move the slider toward right to increase the temperature or move it left to decrease the temperature. You can also use the '+' and the '-' buttons to increase or decrease the temperature by 1 °C (celcius) with every single tap.

2. Increase or Decrease Indoor Unit's Fan Speed

At any instant of time, you may need to increase or decrease the indoor unit's fan speed. Here's how you can do it.

1. On the LG ThinQ app's control panel, tap the 'Fan Speed' option.

2. Here, you will see five speed options and a separate option for 'Auto' speed. Tap the desired level or use the '+' and '-' buttons to increase or decrease the fan speed respectively.

3. You can also enable the option 'Auto' if you wish to let the AC manage the fan speed automatically.

3. Adjust Airflow By Configuring Up/Down and Left/Right Swing Function

The airflow must be adjusted on your LG air conditioner, so that it evenly cools your rooms. The LG 5 star Wi-Fi ACs support both the up/down and left/right swing to direct the airflow in every corner of the room. To configure the swing function on your LG AC, follow the steps given below.

1. Tap the 'Airflow' flow in the main controls section within the smart home app.

2. Here, you will see two options 'UP/DOWN' and 'LEFT/RIGHT.'

3. If all the bars inside the airflow swing are grey then this means the swing is disabled.
4. To enable the up/down swing function tap the up/down arrows. Tapping the arrow button will activate only one mode of the up/down swing. There are a total of six up/down swing modes.
5. If you wish to set the up/down swing to work continuously then you have to enable all the six swing levels. To do this tap the 'Up/Down Swing' option to enable. Enabling this option will activate the auto up/down swing.
6. To disable the swing from any level just tap the 'Up/Down Swing' option to enable it and then disable it. You will see that all the swing levels turn grey which means that it has been disabled.
7. Similarly, you can configure the left/right swing as per your convenience.

4. Schedule Your LG AC For Auto Start and Off

You can set a schedule for your LG AC which will automatically turn it on and turn it off at your desired times. The 'Schedule' function is extremely useful and must be used while you go to bed for a sleep. Follow the steps below to configure the schedule option.

1. Tap the 'Schedule' option on the main controls screen.

2. Tap 'Turn On' option and set a time at which you wish your LG AC to turn on automatically.

3. Similarly, tap 'Turn Off' and set a time at which you wish your LG AC to turn off automatically.
4. Now, your LG AC will turn on and off at the set time interval. But please note that this would be for one time only. If you wish to set a daily schedule or a schedule that you wish to repeat on multiple days then you have to configure this setting.
5. Under 'Repeat Schedule' simply tap 'Add Schedule.'
6. Now select the 'Start Time' at which you want your LG AC to turn on automatically. Also, under the 'Repeat' option select the days you wish to repeat this schedule. If all the days are visible in blue then this means the schedule will repeat on all days. Tap the day to unselect on which you wish not to repeat the schedule.

7. Now come under 'Operation Settings' tap 'Power' and then select/tap 'Turn On.'
8. Here, you can configure settings such as 'Operating Mode', 'Target Temperature', and 'Fan Speed.' Tap 'Save' to save the schedule for automatic 'Turn On.'
9. Now we have to set a schedule for auto turn off. However, this is optional and you can choose to skip it if you wish.
10. Under the 'Repeat Schedule' tap 'Add Schedule' again. Select the 'Start Time' at which you wish your LG AC to turn off automatically. Also, select the days as per your turn on schedule.
11. Under 'Operation Settings' tap 'Power' and select 'Turn Off.' Finally, tap 'Save' to save this auto turn off schedule.

Note: The auto turn on and turn off times would be different depending on how long you want your LG to operate. For example, if you have set the start time as 11:00AM in the morning and you want the AC to operate 1 hour then turn off time would be 12:00PM. You can select any time range as per your usage and requirement.

5. Enable Sleep Timer For Your LG AC On LG ThinQ

You can enable sleep timer for your air conditioner, after running for that particular time period, your AC will turn off automatically. You can set the sleep timer starting from 30 minutes and up to 7 hours.

1. Tap the 'Sleep Timer' option on the main controls panel.

2. You will be asked to set a countdown timer for a time period. You can select 30 minutes, 1 hour, 2 hours, 3 hours and so on. The maximum time can be set for 7 hours only.

3. Tap 'Save' to set the countdown timer. If you wish to disable this option, tap the blue slider button just next to the 'Sleep Timer.'

6. Make Your 5-star LG AC Convertible To Save Power In LG ThinQ

One of the most useful features of your LG 5-star Wi-Fi AC is that you can make it convertible. The convertible feature lets you use your LG AC at 40%, 60% or 80% efficiency. By using this feature, you can save power and reduce your electricity bills. To configure this feature follow the steps below.

1. Tap the 'AI Plus Convertible' option and select the LG AC efficiency from 40%, 60% or 80%.

2. If you wish you can set your LG AC's to AI Plus (LG's artificial intelligence feature) to let your Air conditioner control the cooling capacity automatically based on current conditions.

7. How to Use Smart Diagnosis In LG ThinQ

The 'Smart Diagnosis' feature can help you identify faults with your AC's temperature sensor, digital inverter, fan motor, voltage, compressor, refrigerant, pressure sensor and the current sensor.

1. To use this feature, go to Useful Features > Smart Diagnosis option and then tap 'Get Started' button to start the smart diagnosis. If smart diagnosis finds an issue with the AC's hardware, it will report it and show you the results.
