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: “――”

34 Compressor discharge temp.(T5) The display value is between 30~129 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 compressor
discharge temp. is 105 degree.)
35 AD value of current
The display value is hex number.
For example ,the digital display tube show “Cd”, it means AD value is 205. 36 AD value of voltage
37 EXV open angle for A indoor unit
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.)
38 EXV open angle for B indoor unit
39 EXV open angle for C indoor unit
40 EXV open angle for D indoor unit
41 EXV open angle for E indoor unit
42 Frequency limit symbol
Bit7
Frequency limit caused by IGBT
radiator
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.
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
43 Average value of T2 (Sum T2 value of all indoor units)/( number of indoor units in good connection)
