Connect to Wi-Fi:

• Ensure your smartphone or tablet is connected to the same Wi-Fi network you want your AC to connect to.
• Enter your Wi-Fi credentials in the TCL Home app when prompted.
• Wait for the AC to connect to the Wi-Fi network. This may take a few minutes.

Configure Your AC Settings:

• Once the AC is connected and Matter integration is enabled, you can configure various settings in the TCL Home app.
• Set your preferred temperature, fan speed, and mode (cool, heat, fan, etc.).

Link with Smart Home Assistant (Optional):

If you have a smart home assistant (Google Assistant, Amazon Alexa), you can link your TCL account to control the AC with voice commands.

Troubleshooting Tips:

• Connection Issues: Ensure your Wi-Fi network is stable and within range of the AC unit. Restart your router if necessary.
• Pairing Problems: Make sure the AC is in pairing mode.
• App Issues: Ensure the TCL Home app is up to date. Reinstall the app if problems persist.
