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 R10 (12.7K
Ω
) and R11 (12.7K
Ω
).
Relation between temperature and voltage is following Table 3-1.
CC5, 6 is Noise filter.
