HOT WATER SUPPLIER HAVING A MALFUNCTION DEVICE

摘要

A malfunction detection device for a hot water supplier has a tank temperature detection thermistor (40) for detecting a hot water temperature of a hot water storage tank (3) and is configured such that when the detected hot water temperature of the hot water storage tank (3) is a reference temperature or higher, a relay (49) provided at a tank printed circuit board (45) stops power supply from a tank unit (2) to a heat pump unit (1). A heat pump shutdown command is a standby power saving command for saving a standby power of the heat pump unit (1).
