What are basic function of Samsung AC modes?

The Smart AC Control supports many modes, so it is possible that your tado° app may show more modes than those available on your air conditioner.

In Auto mode, the air conditioner will automatically set the temperature and fan speed

depending on the room temperature detected by the room temperature.

• If using a multi-system, in Auto operation, the system selects a temperature setting and an appropriate operation mode (COOL or HEAT) based on the room temperature at the start of the operation.
  

 In Cool mode, the air conditioner will cool your room. You can  adjust the temperature and

    the fan speed to feel cooler in hot season.

• If current outside temperatures are much higher than the selected indoor temperature, it may take time to bring the inner temperature to the desired coolness.
•  Quiet mode ( ) makes the noise quieter during operating the indoor unit in the Cool mode.

The air conditioner in Dry mode acts like a dehumidifier by removing moisture from the indoor air. Dry mode makes the air feel refreshing in a humid climate.

To maximize the dehumidification capacity during the Dry operation, the  air conditioner could be operating at lower or higher temperature than the remote controller set temperature
