Electrical Control Function
Electrical Control System 125
07 Condenser pipe temp.(T3)
display tube will show “70”. If the indoor unit is not connected,
the digital display tube will show: “――”
08 Outdoor ambient temp.(T4)
09 Compressor discharge temp.(T5)
The display value is between 0~129 degree.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)
10 AD value of current
The display value is hex number.
11 AD value of voltage
12 Indoor unit running mode code
Off:0, Fan only 1,Cooling:2, Heating:3, Forced cooling:4,
Dry:6,Self-clean:8, Forced defrosting:10
13 Outdoor unit running mode code
Off:0, Fan only 1,Cooling:2, Heating:3, Forced cooling:4,
Dry:6,Self-clean:8, Forced defrosting:10
14 EXV open angle
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.)
15 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

17 IGBT radiator temp.
The display value is between 0~130 degree..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)

Condenser pipe temp. of 1# indoor unit 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 capacity demand is 0, , the
digital display tube will show “0. If the indoor unit is not
connected, the digital display tube will show: “――”(heating

22 1# Indoor unit capacity demand code
Actual data*HP*10
If capacity demand code is higher than 99, the digital display
tube will show single digit and tens digit. (For example, the
digital display tube show “5.0”,it means the capacity demand
is 15. the digital display tube show “60”,it means the capacity
demand is 6.0). If the indoor unit is not connected, the digital
display tube will show: “――”
23 2# Indoor unit capacity demand code
24 Reserved
25 Indoor room temp. of 1# indoor unit
If the temp. is lower than -9 degree, the digital display tube will
show “9”.If the temp. is higher than 70 degree, the digital
display tube will show “70”. If the capacity demand is 0, , the
digital display tube will show “0. If the indoor unit is not
connected, the digital display tube will show: “――”
