Abstract: In an electronic control device for electric ranges having a plurality of individual heat settings to selectively energize a heating element of the range under the control of a digital input to produce switching pulses having different on-off ratios, each heat setting has an associated time controlled constant power period in the start-cooking or roasting range, and in the subsequent finish-cooking range there are produced switch-on and switch-off pulses having a constant time pattern at every heat setting, while the time duration of the constant power period and the duration of the switch-on pulses in the finish-cooking range are different from one heat setting to another.
