What to do if the Mijia Air Conditioner Pro Eco Inverter 1.0 HP cannot adjust the temperature?

If the Mijia Air Conditioner Pro Eco Inverter 1.0 HP cannot adjust the temperature, please follow the troubleshooting steps below:
When the remote control doesn't work:
1. First, check whether the remote control batteries have power. If they are dead, replace them with new ones;
2. If the batteries are working, check whether the display is normal and if other buttons on the remote work properly;
3. Check whether the air conditioner is in ECO mode or Sleep mode, as these modes limit temperature adjustment;
4. After confirming that the remote is functional, check whether the air conditioner is receiving the signal (e.g., listen for a beep sound);
5. Turn off the power to the air conditioner for 3–5 minutes, then restart it and see if the issue is resolved;
6. If the issue persists, please contact after-sales service.
When the Xiaomi Home App doesn't work:
1. Disconnect the App completely (remove the device from Xiaomi Home App and reset the air conditioner's Wi-Fi), and try using only the remote control;
2. Check whether other household devices are interfering with the signal. Observe if the issue occurs after operating another remote control;
3. If the above steps do not resolve the problem, please contact after-sales service;
4. If the issue is resolved, it is due to smart settings in the Xiaomi Home App (such as an automation like Sleep curve or ECO mode). In that case, reset the air conditioner's Wi-Fi, reconnect it in Xiaomi Home App, and clear the device’s historical data.
If both the remote control and the Xiaomi Home App cannot control the device, please contact after-sales service for inspection.
