9. Heat Exchanger Thermistor Circuit
Heat exchanger temperature is noticed inside the room
(1) Preheating
(2) Low-temperature defrosts at cooling
and
dehumidification operation time.
(3) Not working of reversing valve or detection of opening of heat exchanger thermistor is controlled.
According to heat exchanger temperature, the voltage of point becomes as it is shown in Fig. 9-2.
