Abstract
A relay device and a hot water supply device are provided. A communication adapter downloads an update program for software update of the constituent devices of a hot water supply system from a management center via a communication network (the Internet). The downloaded update program is stored in a storage part in the communication adapter. When there is more than one software update target device, the communication adapter sequentially selects one of the target devices and sequentially transmits the update program stored in the storage part to the devices one by one via a communication line.
Claims16
A relay device communicably connected between a hot water supply system and a management device of the hot water supply system, the relay device comprising:
- a first communication part configured to transmit/receive information to/from the hot water supply system via a communication line;
- a second communication part configured to transmit/receive information to/from the management device via a communication network;
- a storage part comprising a program storage area;
- and
- a control part controlling operations of the first communication part and the second communication part and writing and reading to/from the program storage area,
- wherein the first communication part receives, from each of a plurality of devices which are components of the hot water supply system, identification information and version information of software of the devices,
- the second communication part receives an update program for software update of the devices from the management device,
- the control part writes the update program received by the second communication part to the program storage area and extracts one or more software update target devices from the devices based on the identification information and the version information of the devices, and
- when there are more than one software update target device, the control part sequentially selects one of the software update target devices and transmits the update program stored in the program storage area to the selected one device by the first communication part.
