<P>PROBLEM TO BE SOLVED: To provide a water distribution valve control device enabling water distribution to be excellently controlled for users even when a failure such as breakdown occurs in the water distribution valve control device. <P>SOLUTION: A water distribution valve control device 100 comprises: a controller 1; a signal input-output part 2 to which a target opening degree S2 and a normality signal S1 are inputted from the controller 1; and a valve adjusting part 3 connected to the signal input-output part 2. When a failure occurs in the water distribution valve control device 100, the signal input-output part 2 stops output of the normality signal S1 to the valve adjusting part 3 and maintains the opening degree of a water distribution valve 202 at an opening degree in the event that the failure has occurred. <P>COPYRIGHT: (C)2012,JPO&INPIT |
