ABSTRACT:
A first control device controls a temperature of an object so as to make it near a first predetermined temperature. A second control device stops heating the object if a temperature thereof reaches a second predetermined temperature as a result of a temperature thereof increasing because the first control device is substantially disabled. The second predetermined temperature is higher than the first predetermined temperature.
