Sontec has been involved in the field of building technology and KNX since 1999. As an integrator numerous large and small projects with KNX were implemented. The ever increasing demand for specific special solutions has given them the motivation to set-up their own development department – in which they design and implement both hardware and software solutions. With the in-house control and visualisation system "Visu2" required standard automation functions can be extended in many projects. By joining as a KNX Member and gaining access to appropriate vendor tools and specifications they will now expand their services in the field KNX and thus guarantee their customers expertise to the "last bit".
