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.
