limit caused by T4,
T3 and current.
Bit3
Frequency limit caused by T3.
Bit2
Frequency limit caused by T5.
Bit1

IGBT radiator temp.
The display value is between 30~120 degree. If the temp. is
lower than 30 degree, the digital display tube will show
“30”.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)

Indoor unit number
The indoor unit can communicate with outdoor unit well.
General:1, Twins:2

Evaporator pipe temp. T2 of 1# indoor unit
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 indoor unit is not
connected, the digital display tube will show: “――”

1# Indoor unit capacity demand code
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: “――”

Room temp. T1 of 1# indoor unit
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 indoor unit is not
connected, the digital display tube will show: “――”
