If the fan speed of the Mijia Air Conditioner Pro Eco 3.5 kW cannot be adjusted, please follow these steps:
When the remote control cannot adjust the fan speed:
1. Check whether the remote control batteries have power. If they are depleted and the remote is unresponsive, replace them with new ones;
2. After confirming the batteries are functional, check whether the remote control display is working and if other buttons respond correctly;
3. Make sure you are checking the fan speed level in the upper LCD area of the remote control and using the fan speed button to make adjustments;
4. If the remote appears normal, confirm whether the air conditioner is receiving the remote signal, such as by listening for a beep sound;
5. Turn off the air conditioner power for 3 to 5 minutes, then restart it and check if the fan speed adjustment works again;
6. If the issue still cannot be resolved after following the above steps, please request after-sales service for further inspection.
When the Mi Home/Xiaomi Home APP cannot adjust the fan speed:
1. Disconnect the air conditioner from the Mi Home/Xiaomi Home APP completely. Delete the device in the app and reset the air conditioner's Wi-Fi settings. Then control it only using the remote control;
2. Check if there is interference from other remote-controlled devices in your home. Confirm whether the problem occurs when using another device’s remote;
3. If the issue persists after these checks, please request after-sales service for further inspection;
4. If the problem is resolved after disconnection, it is due to smart settings in the Mi Home/Xiaomi Home APP. You can reset the air conditioner's Wi-Fi and reconnect it to the app to clear the previous data.
If both the remote control and the Mi Home/Xiaomi Home APP are unable to adjust the fan speed, please contact after-sales service for inspection.
