If you want to install your Smart AC Control to a different air conditioner, or if you want to reset the installation process as your AC is not responding to the Smart AC Control, please do the following in the tado° app:
Go to Settings > Rooms & Devices.
Select the room in which the Smart AC Control is located.
Select Restart AC Setup.
Restarting the installation won’t delete your tado° rooms or reset Wi-Fi and Smart Schedule settings. However, the Smart AC Control won’t be able to control your air conditioner until the installation is completed.
