The 'Cool' mode ensures a consistent temperature, the 'Fan' mode allows you to adjust airflow speed, the 'Dehumidify' mode reduces excess moisture in the air, and the 'Sleep' mode gradually increases the temperature by 1 centigrade every hour for a more comfortable night's rest. This unit is an all-in-one solution for maintaining your ideal indoor climate. Please note: the included exhaust hose must be connected for the air conditioner to function correctly.
