Abstract

An electronic control for a cooking oven includes an input selection panel for receiving user input selections and control logic responsive to the input, selection panel for establishing a time and temperature profile of the oven cavity and for controlling heating devices according to the time and temperature heating profile entered by the user. The input selection panel includes heating function selection devices for receiving user selection of a heating function from among a plurality of heating functions and timing function selection devices for receiving user selection of at least one timing function from among a plurality of timing functions. The timing functions are independent of the heating functions so that a user may select any combination of timing functions with any selected heating function. The input selection panel includes labeled selection devices and labeled parameter display devices that define a grammatical sentence. The sentence emulates standard instructions in a cooking recipe. The functions and parameters selected by selection devices are laid out with the parameter display devices in a manner that functions are logically selectable from left-to-right across the panel.
