Roth Touchline⁺ App enables you to control your floor heating system either via Wi-Fi when you are at home or via the internet when you are abroad. Once the system has been setup for App control, it is possible for you to see actual temperatures, to change set points and to check and change the mode of operation of the complete system or each single room. With this new Touchline⁺ App, you are able to control more than one controller and you can have controllers placed on several locations controlled by the same App. You will get a nice overview of all your controllers (which you can name) and by pressing the specific controller, you will connect safely via our Roth portal server. Functions: * Quick login on already registered controllers if you save your password at first login. * Same login on all your saved controllers if you want. * System mode can easily be changed from the overview of the controllers. * Easy and foreseeable setting of both the room temperature and room mode. * Possibility to sort the favorite list to place the most used controllers or rooms in the top. * Quick access to all functions via drop-down menu. * Easy set-up when more users are required. * New and improved help menu. First setup of the system must be done locally on the Wi-Fi network where both controller and smart device are connected. This goes for all controllers at all locations. The App supports the following languages: English, Danish, Dutch, Finnish, French, German, Norwegian, Polish, Portuguese, Romanian, Spanish and Swedish.

Bei geeigneten Bedingungen aktiviert das System einen angeschlossenen Ventilator und sorgt so jederzeit für eine effiziente Entfeuchtung im Innenraum.
