If the remote control of the Mijia Air Conditioner Pro Eco 3.5 kW is not working or its buttons are unresponsive, please follow these steps:
1. Check whether the remote control batteries have sufficient power. Replace them if needed;
2. If the issue persists, try restarting the air conditioner by turning off the power and then turning it back on;
3. Check the surrounding environment for possible signal interference. Devices such as routers or high-power appliances placed nearby can affect signal transmission;
4. After installing new batteries, press and hold a button on the remote control. Use your phone’s camera to observe the front of the remote. If you can see a red flashing dot through the camera, it indicates that the remote is transmitting a signal;
5. If the problem still cannot be resolved, please request after-sales service for inspection.
