08 Outdoor ambient temp.(T4)
09 Compressor discharge temp.(T5)
10 AD value of current
11 AD value of voltage
12 Indoor unit running mode code
13 Outdoor unit running mode code
14 EXV open angle
15 Frequency limit symbol
16 DC fan motor speed
17 IGBT radiator temp.
Indoor unit number
18
19 Evaporator pipe temp. T2 of 1# indoor unit
20 Evaporator pipe temp. T2 of 2# indoor unit
21 Evaporator pipe temp. T2 of 3# indoor unit
will show "-9".If the temp. is higher than 70 degree, the
digital display tube will show "70". If the indoor unit is not
connected, the digital display tube will show: "――"
The display value is between 13~129 degree. If the temp. is
lower than 13 degree, the digital display tube will show
"13".If the temp. is higher than 99 degree, the digital display
tube will show single digit and tens digit. (For example, the
digital display tube show "0.5",it means the compressor
discharge temp. is 105 degree. the digital display tube show
"1.6",it means the compressor discharge temp. is 116
degree)
The display value is hex number.
Off:0, Fan only 1,Cooling:2, Heating:3
Off:0, Fan only 1,Cooling:2, Heating:3, Forced cooling:4
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.)

The display value is between 30~120 degree. If the temp. is
lower than 30 degree, the digital display tube will show
"30".If the temp. is higher than 99 degree, the digital display
tube will show single digit and tens digit. (For example, the
digital display tube show "0.5",it means the IGBT radiator
temp. is 105 degree. the digital display tube show "1.6",it
means the IGBT radiator temp. is 116 degree)
The indoor unit can communicate with outdoor unit well.
General:1, Twins:2
If the temp. is lower than 0 degree, the digital display tube
will show "0".If the temp. is higher than 70 degree, the digital
display tube will show "70". If the indoor unit is not
89
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.
