1. A temperature control system for burner means including a pilot burner and a main burner having an associated gas valve means for controlling gas thereto, said system comprising:

  • thermoelectric generator means responsive to a flame from said pilot burner to generate a direct current potential;

    switch means for controlling the opening and closing of said gas valve means;

    converter means for converting the direct current potential to an oscillating current output voltage;

    direct current power supply means for receiving the oscillating output voltage and outputting a direct current (DC) output voltage, wherein said DC output voltage is at a higher potential than said direct current potential;

    control means for controlling operation of said switch means in response to an actual sensed temperature and a setpoint temperature, and for activating said converter means; and

    rechargeable energy source means for supplying power to said control means, said DC output voltage recharging said rechargeable energy source means.
