8. Room Temperature Thermistor Circuit
● Fig. 8-1 shows the room temperature
thermistor circuit.
9. Heat exchanger temperature thermistor circuit
● The voltage at A depends on the room
temperature as shown in Fig. 8-2.
● The circuit detects the indoor heat
exchanger temperature and controls
the following.
(1) Low-temperature defrosting
during cooling and dehumidifying
operation.
The voltage at A depends on the heat
exchanger temperature as shown in
Fig. 9-2.
