Title:
CONTROLLER FOR HOT WATER SUPPLY APPARATUS
Document Type and Number:
Japanese Patent JP3461131
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent inadvertent alteration of target temperature during fluctuating operation.
SOLUTION: This controller 4 for a hot water supply apparatus comprises a bath remote controller 40 and a main remote controller 50 wherein each controller is provided with a voice control section 45 for generating voice from a speaker 48. When the temperature regulation switch 42 of the remote controller 40, 50 is operated during fluctuating operation designated by means of the fluctuating operation switch 44 of the bath remote controller 40, a voice guide notifying the fluctuating operation is delivered from the speaker 48 of the operated remote controller. Since the fluctuating operation can be recognized even if the hot water supply set temperature is tried to be altered inadvertently when the hot water temperature is deviated from a desired level during fluctuating operation, it can be determined that the reason why the hot water supply set temperature can not be altered is not because of failure of the apparatus but because of erroneous operation.
