Lumina Touch+ creates overview in switch box

Seeing the old and new versions side-by-side immediately highlights the evolution in simplicity of use: more information on the touch screen of the operating screens and colours and symbols that make the information much easier for the user to read.  The ease of operation has also increased. Convenient navigation keys on the main screen give users instant access to the most important data in their houses. 

In this way, existing users can also benefit from the new ease of operation. And an expansion is not essential as even existing Lumina computer users can upgrade to the Touch+ version by updating their control computers.
