Control device for hot water supply system, control method of hot water supply system and hot water supply control system

摘要

Problem to be solved: to provide a control system for a hot water supply system capable of reducing power consumption by reducing the number of defrosting operations.The control device of the hot-water supply system is connected to a driving plan preparation unit having a working time to perform a night boiling operation for each group, as well as an operation plan preparation part having a first operation plan and capable of communicating with a plurality of hot water supply units It is equipped with a communication section for receiving the frost detection detection signal transmitted from the hot water supply machine when the frost is detected by the hot water supply machine.The operation planning and preparation section, after receiving a frosting detection signal at the communication unit, in the first operation plan, plans to carry out a subsequent group operation plan after the group where the water feeder of the frosting detection signal belongs to the group where the hot water supply machine belongs Change to the second operation plan to avoid frosting.The communication unit transmits the second operation plan to each hot water feeder of the subsequent group.Diagram
