34 Compressor discharge temp.(Tp) The display value is between 30~129 degrees. If the temp. is lower than 30
degrees, the digital display digits will show “30”.If the temp. is higher than 99
degrees, the digital display tube digits will show singles digit and tens digit.
For example, the digital display digits show “0.5”,it means the compressor
discharge temp. is 105 degrees.)
35 AD value of current
The display value is hex number.
For example ,the digital display digits 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 singles 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 digits 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 Tp.
Bit1
Frequency limit caused by current
Bit0
Frequency limit caused by voltage
