34 Compressor discharge temp.(TP) 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
