Check5.1 Thermistor Resistance CheckCheck No.01 Disconnect the connectors of the thermistors from the PCB, and measure the resistance ofeach thermistor using multimeter.The data is for reference purpose only. When the room temperature thermistor is soldered on a PCB, remove the PCB from thecontrol PCB to measure the resistance. When the connector of indoor heat exchanger thermistor is soldered on a PCB, remove thethermistor and measure the resistance.Thermistor temperature (°C) Resistance (kΩ)–20 197.8–15 148.2–10 112.1–5 85.600 65.935 51.1410 39.9915 31.5220 25.0225 20.0030 16.1035 13.0440 10.6245 8.70750 7.176(R25°C = 20 kΩ, B = 3950 K)(kΩ)15010050–15 0 15 30 45(˚C) (R11905)MultimeterResistance range(R19751) Multimeter (R19752)Room temperaturethermistor
