N Display Remark
00 Normal display Displays running frequency, running state, or malfunction code
01 Indoor unit capacity demand code
Actual data*HP*10
If a capacity demand code is higher than 99, the digital display shows single and
double digits.
For example, if the digital display shows “5.0”, the capacity
demand is 15. If the digital display tube shows “60”, 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 -
06
Indoor unit evaporator outlet temperature
(heating T2, cooling T2B)
If the temperature is lower than -9°C, the digital display shows “-9.” If the temper-
ature is higher than 70°C, the digital display shows “70.” If the indoor unit is not
connected, the digital display shows: “
”
07 Condenser pipe temperature (T3)
08 Outdoor ambient temperature (T4)
09 Compressor discharge temperature (T5)
The display value is between 0–129°C. If the temperature is higher than 99°C, the
digital display shows single and double digits.
For example, if the digital display shows “0.5”, the compressor discharge
temperature is 105°C.
If the digital display shows “1.6,” the compressor discharge temperature is 116°C.
10 AD value of current
The display value is a hexidecimal 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 shows single and double digits.
For example, if the digital display shows “2.0”, the EXV open angle is 120×4=480p.
15 Frequency limit symbol
Bit7
Frequency limit caused by IGBT
radiator
The display value is a hexa-
decimal number. For example,
the digital display show 2A,
then Bit5=1, Bit3=1, and
Bit1=1.
It means 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 volt-
age
16 DC fan motor speed 0: Off, 1: Turbo, 2: High, 3: Medium, 4: Low, 5: Breeze, 6: Supper breeze
17 IGBT radiator temperature
The display value is between 0–30°C. If the temperature is higher than 99°C, the digi-
tal display shows single and double digits.
For example, if the digital display shows “0.5”, the IGBT radiator temperature is 105 °C.
If the digital display shows “1.6”, the IGBT radiator temperature is 116°C.
