Display running frequency, running state or malfunction code
Actual data*HP*10
If the capacity demand code is higher than 99, the digital display tube
displays a single digit and tens digit. (For example, the digital display tube
displays "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 temp. is lower than 0 degree, the digital display tube displays "0". If
the temp. is higher than 70 degree, the digital display tube displays "70".
If the temp. is lower than -9 degree, the digital display tube displays
"-9".If the temp. is higher than 70 degree, the digital display tube
displays "70". If the indoor unit is not connected, the digital display tube
displays: "--"
The display value is between 13~129 degree. If the temp. is lower than
13 degree, the digital display tube displays "13". If the temp. is higher
than 99 degree, the digital display tube displays a single digit and a tens
digit. (For example, if the digital display tube displays "0.5",it means the
compressor discharge temp. is 105 degree. If the digital display tube
displays "1.6",it means the compressor discharge temp. is 116 degrees).
The display value is a hex number.

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

The display value is between 30~120 degrees. If the temp. is lower than
30 degrees, the digital display tube displays "30".If the temp. is higher
than 99 degrees, the digital display tube displays a single digit and a tens
digit. (For example, if the digital display tube displays "0.5",it means the
IGBT radiator temp. is 105 degrees. If the digital display tube displays
"1.6", it means the IGBT radiator temp. is 116 degrees).
The indoor unit can communicate well with the outdoor unit.

If the temp. is lower than 0 degree, the digital display tube displays "0".If
the temp. is higher than 70 degrees, the digital display tube displays "70".
If the indoor unit is not connected, the digital display tube displays: "--".

The display value is a
hex number. For ex.,
the digital display tube
displays 2A, then
Bit5=1, Bit3=1, Bit1=1.
It represents the
frequency limit caused
by T4, T3 and current.
