8-2-5 Temperature Sensor Circuit
The upper circuit reads refrigerator temperature, freezer temperature, and defrost sensor temperature for defrosting and the
indoor temperature for compensating for the surrounding temperature into MICOM.
Opening or short state of each temperature sensor are as follows:
