When heat exchanger sensor (1) temperature of
–20°C or under continued for more than 15
seconds while operation is stopped.
(This is not displayed during operation.)
When room temperature sensor temperature of
–20°C or under continued for more than 15
seconds while operation is stopped.
(This is not displayed during operation.)
When air conditioner is operating and indoor fan
motor is turned ON, indoor fan motor speed of
300 rpm or under continued for more than 30
seconds. (Air conditioner stops.)
After cooling starts, when the temperature
difference at the indoor heat exchanger sensor (1)
after 13 minutes and after 16 minutes is greater
than –2ºC, operation is stopped.
When outdoor air temperature sensor temperature
of –20°C or under continued for more than 10
seconds while operation is stopped.
(This is not displayed during operation.)
When heat exchanger sensor temperature of –20
°C or under continued for more than 10 seconds
while operation is stopped.
(This is not displayed during operation.)
When heat exchanger sensor (2) temperature of
–20°C or under continued for more than 15
seconds while operation is stopped.
(This is not displayed during operation.)
After the decision speed has been 0 rps or more for
9 continuous minutes and the discharge pipe sensor
has sent a 10 second or more broken wire signal.
(Compressor is stopped.)
After the decision speed has been 0 rps or more for
9 continuous minutes and the
power transistor
sensor has sent a 10 second or more broken wire
signal. (Compressor is stopped.)
