Air Conditioner Operation

Operating Sequence in Different Modes

➠ In cooling or heating mode, the air conditioner maintains the set temperature with an accuracy of ±1°C.

➠ If the set temperature in cooling mode is more than 1°C lower than the ambient temperature, the air conditioner will not start.

➠ If the set temperature in heating mode is more than 1°C higher than the ambient temperature, the air conditioner will not start.

➠ In AUTO mode, temperature cannot be adjusted manually; the air conditioner automatically maintains a comfortable temperature of 23±2°C. If the temperature is +20°C, the air conditioner automatically starts in heating mode. At +26°C, the air conditioner switches to cooling mode.

➠ In dehumidification (DRY) mode, the air conditioner maintains the set temperature with an accuracy of ±2°C. If the room temperature is more than 2°C above the set temperature when the air conditioner is turned on, it will operate in cooling mode.

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

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

➠ In Sleep mode during heating, after the first hour the set temperature automatically decreases by 1°C, and after the second hour by another 1°C. The temperature then remains unchanged.

❗👉➨ In Sleep mode, the TIMER function is disabled.

Additional Functions

BLOW (Self-Cleaning) Function

The BLOW function (self-cleaning) is designed to remove moisture from the surface of the evaporator and internal cavities of the unit. Removing moisture prevents the growth of bacteria inside the unit.
