1) When the door is opened, the door S/W closed and MICOM input is ‘Low’.

Then the door-open is sensed.

2) When the door is closed, the door S/W is opened and MICOM input is ‘high’.

Then the door closed is sensed.

1) “V” motor’s location sensing which is for G.A. fuzzy control is done by reed S/W.

2) There occure a “high” to “Low” and “Low” to “High” conversion period on con02 pin6 by the

motion of swing fan. “V” motor’s location is detected by it
