Abstract:
To provide a water supply device which enables one of a plurality of processors mounted on a single substrate to detect abnormality in another processor and perform back-up operation.SOLUTION: A water supply device comprises a processor mounted substrate with a first processor and a second processor having a lower role than the first processor. The second processor transmits an operation confirmation request to the first processor in a first operation state. When receiving the operation confirmation request from the second processor, the first processor returns an operation confirmation response. When the second processor does not receive the operation confirmation response corresponding to the latest operation confirmation request already transmitted to the first processor within a certain period since the transmission of the latest operation confirmation request while the first processor controls an inverter, the second processor switches off the first processor at least once and then transfers to a second operation state to control the inverter.SELECTED DRAWING: Figure 1
