Method of
Malfunction
Detection
High-pressure control (stop) is activated in the cooling mode if the temperature being sensed by
the heat exchanger thermistor exceeds the limit.
The temperature detected by the outdoor heat exchanger thermistor is used to determine the
abnormal thermistor.
Malfunction
Decision
Conditions
Activated when the temperature being sensed by the heat exchanger thermistor rises above
68°C.
Deactivated when the temperature drops below 50°C.
When the outdoor heat exchanger thermistor input is 4.96 V or more during compressor
operation.
Supposed
Causes
The installation space is not large enough.
Faulty outdoor heat exchanger thermistor
Stop valve closed
Dirty heat exchanger
