2. Error detection method
Anomalously low temperature
or high temperature (resistance)
is detected on the indoor heat
exchanger sensor (Th2
1
, Th2
2
).
3.
Condition of Error displayed
• When the temperature sensor
detects -28
°C or lower for 15
seconds continuously, the
compressor stops. After 3-
minutes delay, the compressor
starts again automatically,
but if this error occurs again
within 60 minutes after the
initial detection.
4. Presumable cause
• Defective indoor heat
exchanger sensor connector
• Indoor heat exchanger
temperature sensor anomaly
• Faulty indoor control PCB
