The Gira Pushbutton Sensor 3 Komfort, 4-gang (5134 00) provides a multi-control wall interface for KNX installations. It is intended for use where occupants need manual access to several configured building functions from one location. ETS commissioning defines the functions available for the specific application, so integrators should consult the relevant Gira application description rather than assume every function is supported. The product belongs to the Komfort version of the Pushbutton Sensor 3 range. Before specifying it, verify the compatible bus coupler, rocker set and design frame, together with the mounting dimensions and wiring requirements. Use the current manufacturer documentation to confirm the exact feature set for article 5134 00.
