Air Conditioner Operating Sequence in Different Modes

➠ In cooling or heating mode, the air conditioner maintains the set temperature within ±1 °C. If the set cooling temperature is higher than the ambient temperature by more than 1 °C, the unit will operate in ventilation mode.

➠ If the set heating temperature is lower than the ambient temperature by more than 1 °C, the unit will operate in ventilation mode. In AUTO mode, the temperature is not adjusted manually; the air conditioner automatically maintains a comfortable temperature of 25 ± 2 °C. At 20 °C, the unit will automatically start in heating mode. At 26 °C, it will switch to cooling mode.

➠ In dehumidification (DRY) mode, the unit maintains the set temperature within ±2 °C. If the room temperature exceeds the set temperature by more than 2 °C at startup, the unit will operate in cooling mode.

➠ When the temperature drops more than 2 °C below the set point, the compressor and outdoor unit fan stop, while the indoor unit fan operates at low speed.

➠ In SLEEP** mode when cooling, the set temperature increases automatically by 1 °C after the first hour and by another 1 °C after the second hour. The temperature then remains unchanged.

➠ In SLEEP** mode when heating, the set temperature decreases automatically by 2 °C after the first hour and by another 2 °C after the second hour. The temperature then remains unchanged.
