Frequency limit symbol
Bit7
Frequency limit caused by
IGBT radiator
The display value is a
hexidecimal number.
For example, the
digital display show
2A, then Bit5=1,
Bit3=1, and Bit1=1.
This means that a
frequency limit may be
caused by current, IPM
or T3.
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

T2B fault
00:No fault,01:T2B-A fault, ,02:T2B-B fault ,03:T2B-C
fault,04:T2B-D fault, 05:T2B-E fault, 06:T2B-F fault(The display
priority is A-B-C-D-E-F)

Average value of T2
(Sum T2 value of all indoor units)/(number of indoor units in
good connection)( The heating is the average value of T2, and
the cooling is the average value of T2B)
