Group button BA 1-way KNX. Group button BA 1-way flush-mounted, conventional rockers can be placed on the group button BA 1-way. Two switching points are available. The group button BA 1-way is a KNX user module with an integrated bus coupler and support ring. It is dimensioned for installation in standard 58 mm flush-mounted switch boxes. It can be mounted either via the support ring using the device screws on the switch box or using claw fastening. A connection terminal is required to connect the bus line. The group button BA 1-way has a button mechanism with a middle position for adapting switch rockers from the conventional switch range of all Berker design lines, except ARSYS wg flush-mounted. When using rockers with a lens, the integrated LED can be used either as a status display or as an orientation light. Each button press on the 1-way group button BA causes the integrated bus coupler to generate a telegram and send it to the bus. The telegram format depends on the parameterized application. Depending on the selected parameterization, switching, touch, dimming or blind telegrams can be sent.
