Wiring a bedroom on one bus cable

Four dimmable circuits, three glass panels, a heating zone — and every control decision carried by a single Velbus bus cable. The loads come home to the cabinet; the logic lives in software links. Use the panels below the plan to operate the room.

Concept animation, not an installation guide — routes are illustrative and containment, regulations and load design are out of scope. Circuit levels are example presets (bedsides 70 %, centre 100 %, wall lights a gentle 40 %). Button frames carry valid checksums; every panel LED follows the status broadcast of its load, never the press. The emitter toggle is the point: swap the heating hardware and the Velbus side is untouched — what you see is one option of many.
