Abstract: A digital cooking timer responsive to the temperature of a cooking medium and incorporating minimum and maximum time decoders to insure that the cooking period is within a predetermined range is described. An interval timer sets up a counting period upon immersion of the product in the cooking medium but is inhibited from starting its counting function by the minimum time decoder until elapse of a fixed time period. After elapse of the fixed time period, the interval timer is enabled when and if the cooking medium reaches a predetermined temperature. The maximum time decoder provides an override control that energizes the control device after a fixed period in the absence of an energizing signal for the control device from the interval timer.
