definition
Discharge temperature fault
2. Error definition and error detection method
1) If the discharge temperature of 120 °C [248°F] or more is detected during the above operation (the first detection), the outdoor
unit stops once, turns to anti-restart mode for 3 minutes, and restarts after 3 minutes automatically.
2) If the discharge temperature of 120° C [248°F] or more is detected again (the second detection) within 30 minutes after the
second stop of the outdoor unit described above, the mode will be changed to 3 - minute restart mode, then the outdoor unit
will restart in 3 minutes.
3) If the discharge temperature of 120°C [248°F] or more is detected (the 30th detection) within 30 minutes after the stop of the
outdoor unit described above (regardless of the first or the 29th stop), the outdoor unit will make an error stop, and the error
code "1102" will be displayed.
4) If the discharge temperature of 120°C [248°F] or more is detected more than 30 minutes after the previous stop of the outdoor
unit, the detection is regarded as the first detection, and the operation described in step 1 above will start.
5) For 30 minutes after the stop (the first stop or the second stop) of the outdoor unit, preliminary errors will be displayed on the
LED display.
