Serves as temperature control when thermistor or other temperature-sensing resistive device is connected to input. Dual complementary transistor Q1 is high-stability d-c amplifier, with zener diode CR1 providing threshold level. With sharp-breaking charatcteristic for zener, hysteresis con be less than 10 mv between turn-on end turn-off. -P. C. Murray, Accurate DC-Level Detector, EEE, 13:12, p 65.
