NOTE The oven temp was checked by the thermometer when each stage is 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".
A cooling fan continues the rotation 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.)
