Thermistor temperature is “-6ºC or higher”
continuously for 6 hours or longer.
F-thermistor temperature is “0ºC or higher”
continuously for 6 hours or longer.
R-thermistor temperature is “+10ºC or higher”
continuously for 6 hours or longer.
R-thermistor temperature is “lower than damper
closing temperature 5ºC” continuously for 2 hours
or longer.
External air temperature is “40ºC or higher”
continuously three times at external air
temperature data update timing.
Door open status has continued for 15 minutes
or longer, or door opening frequency is 200 times
or more/day.
The inverter microprocessor detected
a compressor wiring error.
The inverter microprocessor detected
compressor overload status.
The inverter microprocessor detected abnormal
drop of compressor rotation speed.
The inverter microprocessor detected
a compressor startup fault.
The inverter microprocessor detected overcurrent
in the compressor drive circuit.
Communication error between main
microprocessor and inverter microprocessor
The inverter microprocessor detected
a compressor motor position error.
* The external air temperature thermistor is located on the operation PWB.
