Abstract
When interruption of electric service occurs, each of a number of electric actuators forcibly drives a motor using electric energy stored in an electricity storing portion and returns a valve to a predetermined opening position. When receiving a charge start command from a host device, each of the electric actuators starts the charging of the electricity storing portion. The host device divides the electric actuators into groups according to predetermined priority of charging and transmits charge start commands to the electric actuators for each of the groups in order of the priority.
