Abstract
A system for maintaining appropriate control of an actuator in the event of a power disruption without being adversely affected by the period of the power disruption. The actuator may close during the power disruption but will be fully opened upon the return of power to the system. After being opened, the actuator may be kept open with less power than needed for opening it.
