AU482FIBHA: function specification of SW01, SW02, SW04, SW05, SW06, SW07
Table 1
SW01 SW02 Display of 7 segments LED (LD1,LD2,LD3)
0 0 FFF shows capability overloading (if capability overloading function is chose)
Outdoor diagnosis code
1 Outdoor running mode
2 Defrosting area set: display 1------shows that L is set at "12"
When the following condition is available, the unit enters into defrosting running:
(TE: defrosting temp., TA: ambient temp.)
TE≤C×TA－α
Note：C：TA＜0℃，C=0.8
The value of α can be set according to the selection of jump wiring:

5
INV receiving frequency（decimalism） e.g. 84 stands for 84HZ
6
Quantity of indoor units connected（decimalism） e.g. 6 stands for 6 indoor units
7 Back up running: TS sensor: 1 ,
This function is preset and not available.
8 Back up running: TA sensor: 1 ,
This function is preset and not available.
9 Back up running: PD sensor: 1 ,
This function is preset and not available.
13 Display compensation of capacity class: 4------class 4, 6-----class 6
After the start-up of system is over, the frequency of compressor has gotten the
target frequency confirmed by the request of indoor unit capacity for 5 minutes,
and then the unit will modulate the capacity.
(Note: class 4 and class 6 can be selected. Class 4 is that the capacity class
whose range is from 4 classes higher to 3 classes lower than the target frequency.
Class 6 is that the capacity class whose range is from 6 classes higher to 4
classes lower than the target frequency. For the unit without pressure sensors,
there is no this function.)
14 Display "U" shows that indefinite capacity is chose
Display "d" shows that definite capacity is chose (indoor total capacity can't be
over 130%）
15 Display o1-----stands for HP
Display o2-----stands for HP
Display H1-----shows that can be connected with central communication
