ABSTRACT:
Solenoid valves for controlling the gas flow to burners are controlled by an electronic microprocessor card by means of pulse-width modulated signals. The electronic card can receive signals from a timer to be set by the user, and from means by which the user selects the heat output of the burners. The first of said means to be operated by the user after setting the time makes the relative burner dependent on the timer. When the two data (time and heat output) have been set, the card extinguishes the flame of the dependent burner when the set time has expired.
