<p><P>PROBLEM TO BE SOLVED: To provide a heat source machine communication system that can cope with high-speed data communication while employing hardware resources with traditional slow communication speed. <P>SOLUTION: In a heat source machine communication system configured with a hot-water supply device and one or more communication terminals for performing data communication with the hot-water supply device, the hot-water supply device and at least one communication terminal are provided with switching means 5 which switches a clock frequency for data communication. By the switching means 5 changing a clock frequency, data transmission can be done at both of a traditional communication speed and a higher communication speed between devices provided with the switching means 5. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
