Berker is one of the first manufacturers to bring out a home control unit with a capacitive touch screen, making it incredibly easy to use. The screen functions in a similar way to the iPhone screen, and the Comfort Center 9? is as easy to use as the intuitive smartphone. The central unit makes controlling KNX-controllable building functions as easy as child’s play. It has a comfortable 9-inch display, and all the functions are clearly laid out and quick to browse through, with the most commonly used functions always appearing on the front page. Anything you can’t find straight away can be located in a matter of seconds using the search function.
