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 (T2BA)
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: “--”
18 Indoor unit B evaporator outlet temperature (T2BB)
19 Indoor unit C evaporator outlet temperature (T2BC)
20 Indoor unit D evaporator outlet temperature (T2BD)
21 Indoor unit E evaporator outlet temperature (T2BE)
22 Indoor unit A room temperature (T1A)
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: “--”
23 Indoor unit B room temperature (T1B)
24 Indoor unit C room temperature (T1C)
25 Indoor unit D room temperature (T1D)
26 Indoor unit E room temperature (T1E)
27 Indoor unit A evaporator temperature (T2A)
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: “--”
28 Indoor unit B evaporator temperature (T2B)
29 Indoor unit C evaporator temperature (T2C)
30 Indoor unit D evaporator temperature (T2D)
31 Indoor unit E evaporator temperature (T2E)
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 hexadecimal
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
46 F indoor unit capacity
47 F indoor unit capacity demand code
48 F indoor unit evaporator outlet temperature (T2BF)
49 F indoor unit room temperature (T1F)
50 F indoor unit evaporator temperature (T2F)
51 EXV open angle for F indoor unit
