It is a electric automatic check door circuit diagram, it is fixed a PTC thermal resistor component on the electric check door, this control system is composed of bimetallic strip, electrical heating coil, choke valve relay. When it is lower than the set point of temperature, the choke valve is closed by bimetallic strip, then the starter begins to work, the choke valve relya contact is closed by the voltage of voltage adjuster L terminal, the current flows electrical heating coil, the temperature of bimetallic strip rises, after the temperature rising, the choke valve opens slowly. When the bimetallic strip is heated enough, choke valve opens fully, it uses thermal resistor to control the current of electrical heating coil.
