AUX air conditioner service manual

the temperature difference correction value shall be -1℃，if the wind speed of the indoor fan rises by
one gear, the temperature difference correction value shall be +1℃.
● a)The accumulated operation time of the compressor≥3hour；
b)The continuous operation time of the compressor≥20 minutes；
c) The difference value between TE and TA less than Y℃.
● a）The difference value between TE and TA less than Y℃ and continuously last for 5minutes；
b)The accumulated operation time of the compressor is over than 45minutes；
c)The continuous operation time of the compressor is over than 20minutes；
The air-conditioner starts the defrosting process if satisfying the conditions, and records the TE value
then before defrosting starts. Compare the TE value after defrosting with the one before defrosting, if
the value of the later is not 3℃ more than the former one, it will not start the defrosting process
according to this condition until the mode conversed and the air-conditioner to be restarted for heating
or after another defrosting process;
●The air-conditioner starts time counting after overheating protection delay (the outdoor fan stops)
and starts an force defrosting process two hours later.
②The intelligent defrosting process quit if satisfying one of the below four conditions:
a)The duration of the intelligent defrosting process≥9min；
b)After the 4 minutes defrosting process，if TE≥0℃ and the TE rise by 2℃ within 10seconds；
c)After the 5 minutes defrosting process，if TE≥5℃；
d)Test the current of the compressor 1 minute later after compressor starts, When the current of the
compressor ≥6A（3.2Kw、3.5Kw wall-mounted unit require the current of the compressor≥8A）and
continuous lasts for 5 seconds.
