2. Error definition and error detection method
When a short (high temperature intake) or an open (low temperature intake) of the thermistor is detected (the first detection),
the outdoor unit stops, turns to anti-restart mode for 3 minutes, and restarts when the detected temperature of the thermistor.
When a short or an open is detected again (the second detection) after the first restart of the outdoor unit, the outdoor unit
stops, turns to anti-restart mode for 3 minutes, and restarts in 3 minutes when the detected temperature is within the normal
range.
When a short or an open is detected again (the third detection) after the previous restart of the outdoor unit, the outdoor unit
makes an error stop.
When a short or an open of the thermistor is detected just before the restart of the outdoor unit, the outdoor unit makes an
error stop, and the error code "5102", "5103", 5104", "5105", "5106"or "5107" will appear.
During 3-minute antirestart mode, preliminary errors will be displayed on the LED display.
