64
36
AD value of voltage
For example ,the digital display tube show “Cd”, it means AD value is
205.
37
EXV open angle for A indoor unit
Actual data/4.
If the value is higher than 99, the digital display tube will show single
digit and tens digit.
For example ,the digital display tube show “2.0”,it means the EXV
open angle is 120×4=480p.)
38
EXV open angle for B indoor unit
39
EXV open angle for C indoor unit
40
EXV open angle for D indoor unit
41
EXV open angle for E indoor unit
42
Frequency limit symbol
Bit7
Frequency limit caused by IGBT
radiator
The display value
is hex number. For
example, the
digital display tube
show 2A,then
Bit5=1, Bit3=1,
Bit1=1.
It means
frequency limit
caused by T4,T3
and current.
Bit6
Frequency limit caused by PFC
Bit5
Frequency limit caused by T4.
Bit4
Frequency limit caused by T2.
Bit3
Frequency limit caused by T3.
Bit2
Frequency limit caused by T5.
Bit1
Frequency limit caused by current
Bit0
Frequency limit caused by voltage
43
Average value of T2
(Sum T2 value of all indoor units)/( number of indoor units in good
connection)(cooling:T2B, heating:T2)
44
Outdoor unit fan motor state
Fan off:0, High speed:1, Med speed:2, Low speed:3 Breeze:4, Super
breeze:5
45
The last error or protection code
00 means no malfunction and protection
17.5 Protection
17.5.1 Three minutes delay at restart for compressor.
17.5.2 Temperature protection of compressor discharge.
When the compressor discharge temp. is getting higher, the running frequency will be limited as below rules:

V O L T _ L T M _ F R E Q 2 _ A D D
Note: if the low voltage protection occurs and not resumes within 3min, it will keep the protection always
after restart the machine.
