troubleshooting, then restart debugging from
progress 01 after power is on.
06/oC
Display
circularly
System detects no error on outdoor component.
10s later, next step starts.
07_ Detect
indoor
components
07/XX/error
code
Display
circularly
System detects error on indoor components. XX
means the project code of IDU with error, e.g.
no.1 IDU has d5 and d6 errors, meanwhile no.3
IDU displays error d6 and d7, then the nixie tube
will display “07”, “01”, “d5”, “d6”and “03”
circularly. After errors are eliminated, system will
start next step automatically. If power is off
during troubleshooting, then restart debugging
from progress 01 after power is on.
07/XXXX/error
code
Display
circularly
If errors occur in IDU which the project code is
≥
3-digit number, then it will display the 2 big
digits of project code first, then the 2 small
digits, finally the error code, e.g: L1 error occurs
in no.101 IDU, then the nixie tube will display
“01”,“01” and “L1” circularly. Display method is
the same for several IDUs with multiple errors.
07/oC
Display
circularly
No error on components of IDU. 5s later, next
step starts.
08_ Confirm
preheated
compressor
08/U0
Display
circularly
Preheat time for compressor is less than 8
hours. Display will be as in the left until the
preheat time reaches 8 hours. Press main
board’s SW3 button to confirm manually that the
preheat time has reached 8 hours. Then start
next step. (Note: Compressor may get damaged
if it is started without 8 hours of preheat time)
08/oC
Display
circularly
Compressor has been preheated for 8 hours. 2s
later, next step starts.
09_ Refrigerant
judgments
before startup
09/U4
Display
circularly
System is lack of refrigerant and display will be
as in the left. Please cut off power of IDU and
ODU and check if there is leakage on pipeline.
Solve the leakage problem and complement
refrigerant into the unit. Then connect power
and restart debugging from progress 01. (Note:
Before re-charging refrigerant, unit must be
power off in case system starts progress 10
