Outdoor Unit Features:
Outdoor units are equipped with base heaters that enable efficient operation in heating mode even in extreme cold. The air conditioner activates the defrost mode only when necessary and only for as long as needed to defrost the heat exchanger. This ensures that heating operates almost continuously. AUX air conditioners utilize an intelligent defrost system that improves energy efficiency by 5% and increases heating performance by up to 20% in low outdoor temperatures.
Users can choose between lower and upper air outlet options. This flexibility allows users to adjust the air supply position based on convenience and usage habits:
- Lower Air Outlet: Provides an effect similar to floor heating.
- Upper Air Outlet: Offers faster heating compared to floor heating, delivering a more immediate warming effect.
