Beschreibung
Zusammenfassung:	[Object] To provide an electric valve control device capable of returning the electric valve from a locked state to a normal state and an electric valve device.[Solution] An electric valve control device (70) includes a computer (80) configured to control a stepping motor (66) of an electric valve (5). Upon detection of an out-of-step state of the stepping motor (66) when the stepping motor (66) is controlled to rotate a rotor (41) in a first direction for changing a valve opening degree of the electric valve (5), the computer (80) is configured to control the stepping motor (66) to rotate the rotor (41) in a second direction opposite to the first direction.
