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.
Depending on your AC model, tado° supports the following modes:
This is usually the default mode set on most ACs. In this mode, the AC cools your room to the temperature you set on the AC remote and, then, maintains that temperature.
This is the opposite of the Cool Mode. In this mode, the AC warms your room to the temperature you set on the AC remote and then maintains that temperature.
This mode is usually used to ventilate the room. In this mode, no cooling or heating happens.
In this mode, the AC removes excess moisture from the room. The fan runs at a low speed and the cooling is on for short intervals of time. This mode is usually used during extremely humid weather.
In this mode, the AC automatically switches between different modes to arrive at the most efficient one. The AC automatically cools or heats based on the measured room temperature. Some ACs also set the temperature and fan speed.
You can learn more about the different modes in the manual of your AC.
tado° also does not yet support some other modes like Energy Saving, Eco, Turbo, Sleep, etc.
