KNX Weather Centre Units

The EMX-8 weather centre unit combines the core and the sensors of the Griesser KNX control in a single unit. The central unit offers flexible and extensive options for the solar shading automation of small to large systems, especially in residential construction. The advantage lies in the central configuration and administration of all important automatic programs using ETS. This makes it easy to set interdependencies dealing with automatic timing or shading. Programming and commissioning are quick, secure and simple due to the communication with the motor control via the Griesser object. The Griesser object links the central unit with all motor controls via a group address.
