Document Type and Number:
Japanese Patent JP3081280
Kind Code:
B2
Abstract:
PURPOSE:To ensure the safety by a method wherein a priority order is decided in a way that comparison with a limit temperature is effected once when temperature setting is switched in priority, in a hot water feeder having a priority change-over switch. CONSTITUTION:A priority change-over switch to switch priority to change over priority of temperature setting is located at least to one of a plurality of remote control devices, and a limit temperature is set based on an independently stored safety temperature. Control is made such that two temperatures of the one being the limit temperature and the other being a priority temperature from which priority switching is made are compared with each other by a comparing circuit and when the priority temperature is below the limit temperature, the priority temperature forms a final decision temperature and in a reverse case, the limit temperature forms the final decision temperature. Or, temperature stored in a memory part is compared with a set temperature before priority switching and a higher temperature is set to a limit temperature or after completion of priority switching, the limit temperature is varied to a maximum temperature which is capable of being set and to which priority switching is made.
