How to get started


I have bought and installed the Tado Smart AC control V3

I have installed everything and it has confirmed that it recognise my AC unit.

But where can I find information about the app? what are the meanings of the symbols in the app? Does the AC unit need to be switched on so that Tado can interact with it? in certain videos I have seen previous Tado version used a dot to shot it is connected to the AC, does V3 has the same?

Because what settings I change in the app it doesn´t affect on the AC unit.

So where to find, preferably step by step, guidance how to use the app to control my AC unit?

Thanks for helping me out :)
