If you cannot control the fan speed of the Mijia Air Conditioner Pro Eco 2.6 kW using remote control, please refer to the following methods:
1. Check if the remote control battery has power. If depleted, replace it with a new battery;

3. Please confirm if you can view the fan speed level on the LCD display area at the top of the remote control, and adjust it using the Fan Speed button;
4. If the remote control is functioning properly, ensure the air conditioner is receiving the remote signal (listen for a beeping sound);
5. Please turn off the air conditioner for 3 to 5 minutes, then restart it and check if it can be restored.
If the issue persists, please contact the after-sales service for further inspection.
If you cannot control the fan speed of the air conditioner using the Mi Home/Xiaomi Home APP, please refer to the following methods:
1. Remove the device from the Mi Home/Xiaomi Home APP, reset the air conditioner’s Wi-Fi, and control it using only the remote control;
2. Check if the issue occurs when using other remote-controlled devices at home to rule out signal interference;
3. If the issue persists after the above troubleshooting, please contact the after-sales service for inspection;
4. If the issue is resolved, check if the Mi Home/Xiaomi Home APP settings are affecting operation. You can reset the air conditioner’s Wi-Fi, reconnect to the Mi Home/Xiaomi Home APP, and clear historical data.
If both the remote control and the Mi Home/Xiaomi Home APP are unable to control the device, please contact the after-sales service for inspection.
