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)
44 Outdoor unit fan motor state 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
