NOTE The oven temp was checked by the thermometer when each stages are started .
If the oven temp is same or higher than 105 ˚ C, the oven was judged as "with preheating".
When the oven temp is lower than 105 ˚ C or the cooling fan stops, the oven was judged as "without
preheating".
The cooling fan continues to rotate when Oven temperature is more than 120 ˚ C. Then,
it stops when it is less than 105 ˚ C
NOW COOLING is indicated during the cooling fan movement after operation is finished.
(It isn't indicated during a fan movement to stop on the way.)
