What to do if my Aqara Thermostat LCD screen displays a 6 fault icon?

If the LCD screen on your Aqara Thermostat displays a '6' fault icon, there are several potential causes. First, the thermostat might not be installed correctly; try removing it from the valve, taking out the batteries, waiting 30 seconds, and then reinstalling it to see if the problem goes away. Also, the temperature might be set too high, so try replacing the batteries. There could be an issue with the valve itself, in which case you should replace the valve, remove the batteries, wait 30 seconds, and reinstall the thermostat. Finally, the room may be too large for the radiator, or it might be over-ventilated; consider replacing the radiator or ensuring that doors and windows are properly closed.
