Error Detection
Method
Temperature detected by inside air temperature sensor is used to detect errors.
Error Generating
Conditions
When value detected by inside air temperature sensor is -40ºC or below (open circuit) or 70ºC or higher
(shorting).
Possible Causes Faulty sensor
Broken wire
Faulty control PCB
Faulty contact in connector
Troubleshooting
Note: Note 1:
Refer to the thermistor temperature - resistance conversion table when measuring resistance.
Thermistor temperature - resistance conversion table
If measured value deviates significantly from above values, thermistor is faulty.
Use tester to check resistance
Remove Indoor air
thermistor (R1T) from
X12A (3P) on control
PCB, and measure
resistance.
Is
thermistor
normal?
Note 1
YES
NO
Replace indoor air
thermistor.
If there is no faulty
contact, replace
control PCB.
