Cook Surface Sensors. The Infinite Cooking System creates heat only after sensing a pan on the cooking surface. The cook surface diameters respond to both the presence and precise size of a pan. The heat is transferred directly to the pan so the cooktop surface remains cool to the touch. Cooking Flexibility Five induction zones including a 6 in. 7 in. 8 in. and 10 in. combine to create a remarkably versatile cook surface for the ultimate flexibility. Enhanced Settings. Power Boost affords rapid heat acceleration while at the same time reducing energy consumption. For the discerning chef the Keep Warm Setting allows you to maintain the perfect serving temperature of cooked foods directly on the cook surface. And for complete safety digital controls enable shut-off at eighteen hours and discretional lockout from the off position. Precision Touch Controls. Fifteen preset touch settings provide a level of digital heat control that inspires confidence in even the most particular chef.
