Abstract:
To provide a feed water device which decides a current proper wait-and-see operation time conforming to lifestyles of people, enhances an energy saving effect, and can prevent the excess of a start frequency of a pump.SOLUTION: A feed water device with a learning function comprises a control device 40 for performing a water small-quantity stop operation for stopping a pump via a wait-and-see operation of the pump for confirming that a water small-quantity state is continued when detecting the water small-quantity state that a use quantity of the pump at a discharge side is reduced. The control device 40 has a learning unit 42 for learning the adaptability and length of a wait-and-see operation time at which the pump performs a wait-and-see operation by the water small-quantity stop operation on the basis of a use frequency of the water of the pump at the discharge side, and a decision unit 43 for deciding the adaptability of the wait-and-see operation time or its length on the basis of a learning result by the learning unit 42, and an inputted current time.SELECTED DRAWING: Figure 3
