A control circuit for controlling a bimetal actuated choke valve adapted to be driven by a heater energized by electric power whose duty ratio is changed in response to ambient temperature. The control circuit is integrally formed by a hybrid integrated circuit, wherein the characteristics of the duty ratio with respect to the ambient temperature are adjusted by at least one resistance provided externally of the hybrid integrated circuit.
