Abstract
When an ECU is powered on, an overall control unit determines whether a temperature detected by a temperature sensor is lower than or equal to a predetermined temperature. When it is determined that the detected temperature is lower than or equal to the predetermined temperature, the overall control unit provides a second operation start command for operating a valve driving motor control unit in a rotation direction alternately switching mode, to the valve driving motor control unit. When the valve driving motor control unit receives the second operation start command from the overall control unit, the valve driving motor control unit starts operating in the rotation direction alternately switching mode.
