For example ,the digital display tube show “Cd”, it means AD value is
205.
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.)
EXV open angle for B indoor unit
EXV open angle for C indoor unit
EXV open angle for D indoor unit
EXV open angle for E indoor unit
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.
Frequency limit caused by PFC
Frequency limit caused by T4.
Frequency limit caused by T2.
Frequency limit caused by T3.
Frequency limit caused by T5.
Frequency limit caused by current
Frequency limit caused by voltage
(Sum T2 value of all indoor units)/( number of indoor units in good
connection)
Outdoor unit fan motor state
Off:0, High speed:1, Med speed:2, Low speed:3 Breeze:4, Super
breeze:5
The last error or protection code
00 means no malfunction and protection
