The induction cooktop has four cooking zones, 2 @1200 W & 2 @ 2300 W for a total of 7000 W. If one zone is not used, a 300 W boost for five minutes can be applied to each of the other zones, so it’s possible to boost both 2300 W zones to 2600 W & a single 1200 W zone to 1500 without exceeding the capabilities of the device.
I have a whistling stovetop kettle that holds two litres of water. This amount can be boiled in 5½ minutes on one of the larger zones with boost invoked for the first 5 minutes before it automatically drops back to the normal maximum level.
To adjust individual zones, tough the relevant zone selector then slide you finger along the temperature control sensor. Repeat for other zones as needed.
Very impressive technology.
