13 Outdoor unit amendatory capacity demand code
14 The frequency corresponding to the total indoor
units' amendatory capacity demand
15 The frequency after the frequency limit
16 The frequency sending to compressor control
chip
17 Indoor unit A evaporator outlet temperature (T
2B
A)
If the temperature is lower than -9
℃
, the digital display shows “-9.” If the
temperature is higher than 70
℃
, the digital display shows “70.” If the
indoor unit is not connected, the digital display shows: “――”

A) If the temperature is lower than 0
℃
, the digital display shows “0.” If the
temperature is higher than 50 ℃ , the digital display shows “50.” If the
indoor unit is not connected, the digital display shows: “――”

32 Condenser pipe temperature (T3)
33 Outdoor ambient temperature (T4)
34 Compressor discharge temperature (TP) The display value is between 30–129
℃
. If the temperature is lower than
30 ℃ , the digital display shows “30.” If the temperature is higher than
99
℃
, the digital display shows single and double digits. For example, if
the digital display shows “0.5", the compressor discharge temperature is
105
℃ .
35 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.
36 AD value of voltage
37 EXV open angle for A indoor unit
Actual data/4.
If the value is higher than 99, the digital display shows single and double
digits.
For example, if the digital display shows “2.0", 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 a hexidecimal
number. For
example, the
digital display
show 2A, then
Bit5=1, Bit3=1,
and Bit1=1.
This means that
a frequency limit
may be caused
by T4, T3, or the
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
