indoor fan stops immediately.

Overheated protection ：
a)When heating function runs ， if TE ≥ TE9 and last for 10seconds ， the outdoor fan stops ； if TE ≥ TE10
and last for 10seconds, then stop the compressor ； When TE< TE11 and after the 3 minutes protection
delay, the compressor resumes normal working.
b
） .This temperature protection is valid only when the TE temperature sensor runs normally.

The auxiliary electric heating function
① The electric heating function may not start unless the heating mode runs normally e.g. the
compressor starts, the outdoor fan runs, the four-way valve is electrified, the indoor fan is on as well
as the availability of the below conditions:
a)TE < TE12 ；
b)TA < TA3 ；
c)TS – TA ≥ 3 ℃；
d)The compressor runs continuously in heating mode for 4min ；
② The auxiliary electric heating may withdraw working if meet one of the below conditions:
a)TA > TA3 ；
b)TS – TA < 2 ℃；
c)TE > TE11 ；
③ If one of the compressor, four-way valve and indoor fan doesn’t work or there is error feedback
from the indoor fan, the auxiliary electric heating withdraw from work;
④ If the sensor of TE is damaged and the turn-off without non-electricity occurred in the ongoing
auxiliary electric heating process, the indoor fan turns in the low speed wind operation for 40 seconds
and stops
；

Intelligent defrosting function
Under the operation of the intelligent defrosting mode, t ① he air-conditioner starts the defrosting
process if satisfying the requirement of one of the below five conditions (the sub-conditions included
shall all be satisfied). During the defrosting process, the sleeping light is twinkling:
● a) The outdoor fan starts the overloading protection and the outdoor fan stops;
b) Restart the outdoor fan after stop and the continuous running time over than 10 minutes;
c)The accumulated operation time of the compressor
≥ 45min ；
d)The continuous operation time of the compressor ≥ 20min ；
e)TE ≤ TE12 。
●
a) After the 5 minutes operation of the heating mode or 5 minutes later after the defrosting process,
starts the capture motion for the max. difference value between TE and TA, when the difference
between TE and TA being reduced up than X min and the time lasts
≥ 3min ；
b)The continuous operation time of the compressor ≥ 5min ；
c)The accumulated operation time of the compressor ≥ 45min ；
d)TE ≤ TE12 ；
Note ： When the wind speed correction available, if the wind speed of the indoor fan drops by one gear,
