<p><P>PROBLEM TO BE SOLVED: To provide a remote control system for a water heater in which each information processor can confirm operation states of other information processors without affecting transmission of control signals controlling the operation of the water heater. <P>SOLUTION: Each information processor has an its own-processor message board section which stores state information representing its operation state, and an other-processors message board section which stores state information sent from other information processors each time the state information of the processors changes. Each information processor can obtain the latest operation states of the other processors without receiving the state information in short cycles from the other processors by referring to the state information stored in the other-processors message board section, and does not occupy a communication line to transmit the state information, the control signals therefore can speedily be transmitted. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
