Anti-cold wind function when compressor stops

：

①

When TE is in the fall status, if TE>30

℃

,the indoor fan runs at low fan

speed;TE30

≤

℃

,indoor fan turns off;

②

When TE is in the rise status, if TE35

≥

℃

, the indoor fan runs at low fan speed; TE35<

℃

indoor fan turns off;

Residual-heat removing function after air-conditioner stops

：

When TE

＞

℃，

the indoor fan runs at the low fan speed, if

≤

℃

,the indoor fan turns off,

and air-conditioner stops for starting the process of residual heat removal and last for

≤

10seconds, within the 10second of process of residual heat removal, if TE< 35

℃

, the indoor

fan turns off at once.

⑾

Anti-high temperature protection

：

①

when run on Heating mode

，

if TE

≥

℃

and continuously last 10 seconds, the outdoor fan

stops; if TE

≥

℃

and last for 10s

，

the compressor stops again

；

When TE< 52

℃

and

satisfying 3minutes protection delay condition, the compressor resume normal work.

。

②

Such temperature protection is valid only if the TE sensor works normally.

⑿

The defrosting function under heating mode

①

When the outdoor sensor in good condition, the defrosting process starts, and the sleeping
