Error detection condition
• Resistance value of sensor is
infinite or zero. (Open/Short)
• Resistance value of sensor is
infinite or zero. (Open/Short)
• Resistance value of sensor is
infinite or zero. (Open/Short)
• Resistance value of sensor is
infinite or zero. (Open/Short)
Compressor 2 case thermostat
operated.
Temperature change of TK1 could
not be detected though compressor
1 started the operation.
Temperature change of TK2 could
not be detected though compressor
2 started the operation.
Temperature change of TK3 could
not be detected though compressor
started the operation.
Temperature change of TK4 could
not be detected though compressor
started the operation, or the
difference from other TK sensor
changed for a constant time only
within the specified range.
