New concept for KNX beginners

Preconfigured sets CasaConnect KNX

Each set contains typical KNX devices for an appartment or house. Weather station, control panel, room controller, smoke, motion and water detectors and actuators for heating, sun protection, light and for switching have already been addressed at the factory and linked together in a KNX project. After installation, the devices communicate with each other immediately, without ETS.

The individual set-up of the functions is conveniently done at the CasaConnect KNX central unit. You can also get help via the remote maintenance function without the need for a specialist technician to visit you.
