105
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.

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.
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 voltage

17
IGBT radiator temperature
The display value is between 0–30
℃
. 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 IGBT
radiator temperature is 105
℃
.
If the digital display shows “1.6", the IGBT radiator
temperature is 116
℃
.
18
Indoor unit number
The indoor unit can communicate with outdoor unit.
General: 1, Twins: 2
19
Condenser pipe temperature of #1 indoor
unit
If the temperature is lower than 0
℃
, the digital display shows
“0”. If the temperature is higher than 70
℃
, the digital display
shows “70.”
If the capacity demand is 0, the digital display shows “0”.
If the indoor unit is not connected, the digital display shows:
“――”(heating T2
,
cooling T2B)
20
Condenser pipe temperature of #2 indoor
unit
21
Reserved
22
#1 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 reads “5.0”, the capacity
demand is 15.
If the digital display shows “60”, the capacity demand is 6.0.
If the indoor unit is not connected, the digital display shows:
“――”
23
#2 Indoor unit capacity demand code
24
Reserved
25
Indoor room temperature of #1 indoor unit
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 capacity demand is 0, the digital display shows “0”.
If the indoor unit is not connected, the digital display shows:
“――”
26
Indoor room temperature of #2 indoor unit
If the temperature is lower than 0
℃
, the digital display shows
“0”.
If the temperature is higher than 70
℃
, the digital display
shows “70”.
If the capacity demand is 0, the digital display shows “0".
