Room temperature and Evaporator temperature Sensor Input
DESCRIPTION
Number 24, 25 of Micom is Terminal of A/D convertor Input.
Room temperature and Evaporator temperature is sensing by change of Thermister Resistance, Micom is put
in 5V by ratio between R18 (12.7KΩ) and R20 (12.7KΩ).
Relation between temperature and voltage is following Table 3-1.
CC8, CC9 is Noise filter.
