4.2. Indoor fan functions according to set air input. Without high power wind.
4.3. Vertical air blade operates according to operating requirement of remote control.
4.4. Without sleep function. have gotten timing function.
5. Heating Function
5.1. In heating mode.temperature range is set between 16 ℃ and 32 ℃ .
5.2.While in heating function. the compressor cannot be closed within the first 3
minutes.Compressor can only be closed by changing function mode or turning off the
machine.
5.3.Have got function of compensating temperature for 3
℃
. 3
℃
Below measured temperature
at air inlet is considered the compared value to set temperature. (The others modes doesn't
have this function)
5.4.According to the setting temperature. The condition of compressor working is indoor
temperature-3
℃
≤
set temperature-1
℃
.stoping condition is indoor temperature

5.5.Blow rest heat energy function: the indoor fan motor will run in the mute model on the
condition of indoor coil temperature > 30
℃
.the indoor fan motor will turn off when the indoor
coil temperature fall to below 30
℃
.and residual heating function will last less than 40s.And the
four-way valve change in 2min.
5.6.Indoor fan motor control
：
5.6.1.Heating defend cold wind and blow rest heat energy function
：
The wind speed of indoor fan motor can be controlled by T inter- panel. as the following :
Compressor working to prevent cold wind.
1) When the T e(evaporator) presents rising state. When T e
＜
25
℃
, indoor fan motor will turn
off. When 25
℃
≤
T e
＜
30
℃
, the indoor fan motor will blow feeble wind model. When 30
℃
≤
T e
＜
38
℃
, the indoor fan motor will be in mute wind model. When T e
≥
38
℃
the indoor fan motor
will blow setting wind speed.
2) When the T e presents falling state. When T e
＞
34
℃
, the indoor fan motor will blow setting
wind speed; when 28
℃
＜
T e
≤
34
℃
, the indoor fan motor will be in mute wind model. When
23
℃
＜
T e
≤
28
℃
, the inter- fan motor will be in the feeble wind model. When the T e
≤
23
℃
, the
inter- fan will automatically turn off.
