It links the zones specified by the manufacturer into a permitted control arrangement. It does not automatically make every pair of zones one unrestricted cooking surface.
What the observation means
The required cookware size and shape matter. A long griddle may need a flat compatible base and defined placement.
A useful next step
Follow the model's bridging instructions and approved accessory guidance. Confirm the linked indicators before cooking. If only part of the cookware heats unexpectedly, stop and check the arrangement rather than adding an adapter plate or selecting unrelated zones to compensate.
Manuals and supporting guidance
