Thermistor Resistance Check
Check No.01
Disconnect the connectors of the thermistors from the PCB, and measure the resistance of
each thermistor using tester.
The data is for reference purpose only.
When the room temperature thermistor is directly mounted on a PCB, remove the PCB from
the control PCB to measure the resistance.
When the connector of indoor heat exchanger thermistor is soldered on the PCB, remove
the thermistor and measure the resistance.
