00
Normal display
Displays running frequency, running state, or malfunction code
Defrosting mode: “dF” or alternative displays between running
frequency and “dF” (ach appears for 0.5s.)
Forced cooling mode: the LED displays “FC” or alternative
displays between running frequency and “FC” (each appears
for 0.5s).
01
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)
GA algorithm models display “--”
02
The frequency after the
capacity requirement adapter
If the value is higher than 99, the digital display tube will show
single digit and tens digit.
03
Room temperature (T1)
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”.
04
Indoor unit evaporator
temperature (T2)
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 indoor unit is not
connected, the digital display tube will show: “--”
05
Condenser pipe temp.(T3)
06
Outdoor ambient temp.(T4)
07
Compressor discharge temp.
The display value is between 0~199 degree. If the temp. is
lower than 0 degree, the digital display tube will show “0”. 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)
08
AD value of current
The display value is a hex number.
For example, the digital display tube shows “Cd”, it means AD
value is 205.
09
AD value of voltage

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.)
