Electrical Control Function
Electrical Control System 172
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

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.

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 ℃.
The indoor unit can communicate with outdoor unit.
General: 1, Twins: 2
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)
Condenser pipe temperature of #2 indoor
unit
#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:
“――”
#2 Indoor unit capacity demand code
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:
“――”
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".
