The Smart Oven's Element IQ puts the power where it's needed most. For each of the 9 pre-set programs, Element IQ delivers the right power at the right time and when adjusted to taste, it even remembers. Element IQ works much like the dimmer in your light switch-it can turn the power up or down. Instead of the 5 heating elements having a fixed wattage, Element IQ automatically puts the power where it is needed most for the specific cooking task. Not only does the Smart Oven heat up faster than a conventional wall oven, it's also more energy efficient than its predecessor, making it a kitchen tool you will use every day.
