How to control the Mijia Air Conditioner Pro Eco A+++ 9K with the remote control?

The remote control of the Mijia Air Conditioner Pro Eco A+++ 9K uses infrared technology. Simply point it at the front of the air conditioner (where the display screen is) to operate it.
Note:
1. The infrared receiver is located behind the display screen that has a certain level of transparency;
2. The effective range of the remote control is within 8 meters and approximately 45° to the left and right;
3. Avoid placing obstacles between the remote control and the air conditioner, as this can block the infrared signal.
