TEMPERATURE SETTING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a temperature setting method which does not raise the set temperature exceeding a specific temperature even in case of the fault that a switch is continuously in the ON state. SOLUTION: This temperature setting method is so constituted that the set temperature is raised when the switch is changed from OFF to ON by depression until the set temperature reaches the specific temperature and raised continuously when the switch is continuously in the ON state by continuous depression, and then the set temperature is raised exceeding the specific temperature when the switch is changed from ON to OFF by releasing operation after the depression when the set temperature is as high as the specific temperature.
