Temperature control is achieved using the REF-02 +5 V Reference/Thermometer and a CMP-02 Precision Low Input Current Com-parator. The CMP-02 turns on a heating ele-ment driver (Q1) whenever the present temperature drops below a setpoint temperature determined by the ratio of RI to R2. The circuit also provides adjustable hysteresis and single supply operation.
