METHOD FOR CONTROLLING TERMINAL FOR HOT WATER SUPPLY SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a control method for a terminal of a hot water supply system where the operation of a terminal is not restricted by presence of other terminal in a standby state. SOLUTION: Terminals OP1-OP3 of a hot-water supply unit 1 are interconnected by a 2-core communication line L to bring them into a state available of mutual communication. Each of the terminals OP1-OP3 is configured to transmit a prescribed operation maintenance code to other terminals during its operation. On the other hand, a terminal to which an operation start request is made discriminates whether or not the terminal receives the operation maintenance code from the other terminals and does not execute the processing corresponding to the operation start request when receiving the operation maintenance code from the other terminals.
