Abstract
A heating apparatus with a simplified operating panel comprising a multi-command key actively incorporating several similar functions and a voice synthesizer section such as a PARCOR synthesizer is disclosed. The accepted function of the multi-command key or the next operating step is announced by a synthetic voice. A program recall function is provided to confirm each stage of a preset programmed heating at given timing. The heating progress condition detected by a sensor and a timer is announced by a synthetic voice. Any loss of the functions of the sensor or the timer is detected immediately, followed by the stoppage of heating and the alarm and announcement of the fault.
