Absolutely must turn on this switch on your air conditioner

The second tip: Turn on sleep mode at night.
Most people probably haven't used this function and don't understand its specific function. When the air conditioner is in cooling mode, if we select the "sleep" function, after the room temperature reaches the set temperature or after running for 1 hour, the set temperature will automatically rise by 1°C, and after another hour of operation, it will rise by another 1°C. After a total of 8 hours of operation, it will stop running, having risen a total of 2°C in 8 hours. The principle behind sleep mode's energy saving is to reduce the difference between the ambient temperature and the set temperature, making it easier for the compressor to stop, thus saving energy. Additionally, sleep mode will automatically adjust the fan speed to the minimum to prevent catching a cold from strong airflow while sleeping at night, and the noise of the indoor unit will also be minimized. In winter, if the air conditioner is in heating mode, after running in sleep mode for 1 hour, the set temperature will drop by 2°C, and after another hour of operation, it will drop by another 3°C. After a total of 8 hours of operation, the air conditioner will stop running, having dropped a total of 5°C in 8 hours.
