Electrical Control System
If the temp. is lower than -9 degree, the digital display tube will
show "-9".If the temp. is higher than 70 degree, the digital
display tube will show "70". If the indoor unit is not connected,
the digital display tube will show: "――"
The display value is between 0~129 degree.If the temp. is
higher than 99 degree, the digital display tube will show single
digit and tens digit. (For example, the digital display tube show
"0.5",it means the compressor discharge temp. is 105 degree.
the digital display tube show "1.6",it means the compressor
discharge temp. is 116 degree)
The display value is hex number.

Actual data/4.
If the value is higher than 99, the digital display tube will show
single digit and tens digit.
For example ,the digital display tube show "2.0",it means the
EXV open angle is 120×4=480p.)

The display value is between 0~130 degree..If the temp. is
higher than 99 degree, the digital display tube will show single
digit and tens digit. (For example, the digital display tube show
"0.5",it means the IGBT radiator temp. is 105 degree. the
digital display tube show "1.6",it means the IGBT radiator
temp. is 116 degree)
The indoor unit can communicate with outdoor unit well.
General:1, Twins:2
If the temp. is lower than 0 degree, the digital display tube will
show "0".If the temp. is higher than 70 degree, the digital
display tube will show "70". If the capacity demand is 0, , the
digital display tube will show "0. If the indoor unit is not
connected, the digital display tube will show: "――"(heating
T2，cooling T2B)
Actual data*HP*10
If capacity demand code is higher than 99, the digital display
tube will show single digit and tens digit. (For example, the
digital display tube show "5.0",it means the capacity demand
is 15. the digital display tube show "60",it means the capacity
demand is 6.0). If the indoor unit is not connected, the digital
display tube will show: "――"
Electrical Control Function
The display value is hex
number. For example,
the digital display tube
show 2A,then Bit5=1,
Bit3=1, Bit1=1.
It means frequency limit
caused by T4,T3 and
current.
