code
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)
02 Amendatory capacity demand code
03
The frequency after the capacity requirement
transfer
04 The frequency after the frequency limit
05 The frequency of sending to 341 chip
06
Indoor unit evaporator outlet temp.(heating T2
，
cooling T2B)
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”.
07 Condenser pipe temp.(T3) 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: “――”
08 Outdoor ambient temp.(T4)
09 Compressor discharge temp.(T5)
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 displ
ay 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
13 Outdoor unit running mode code Off:0, Fan only 1,Cooling:2, Heating:3, Forced cooling:4
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,
Bit6
Frequency limit caused by
PFC
Bit5 Frequency limit caused by T4.
