gives this failure. Check whether high or low-pressure
switch is broken or not well connected.
F09 DC fan failure (one)
Compressor
speed down
Speed of DC fan or one of the DC fan (for dual fan
system) can't reach the required value or no feedback
signal. Please check whether the PCB or fan motor is
broken.
F10 DC fan failure (two) Compressor stops
Speed of both DC fans (for dual fan system) can't reach
the required value or no feedback signal. Please check
whether the PCB or fan motor is broken.
F11
System evaporating
pressure too low
Compressor stops
If system too low-pressure protection detected by
evaporating pressure sensor happened 3 times in a
certain period of time, it gives this failure code and unit
can't be restarted until repowered. Check whether system
has not enough refrigerant or leakage inside (more likely it
is not enough refrigerant that caused this abnormal
evaporating pressure); whether fan motor and water pump
is working OK; whether condenser is blocked; whether
EEV whether EEV works normally; whether water
temperature too low, and whether water inlet & outlet
temperature has too big difference in cooling(should no
bigger than 8
℃ ).
F12
System condensing
pressure too high
Compressor stops
If system too high-pressure protection detected by
condensing pressure sensor happened 3 times in a certain
period of time, it gives this failure code and unit can't be
restarted until repowered. Check whether water flow rate
is not enough (more likely it is not enough water flow rate
that caused system build up too high pressure); whether
fan motor and water pump is working OK; whether
condenser is blocked; whether EEV works normally;
whether water temperature too high, and whether water
inlet & outlet temperature has too big difference (should no
bigger than 8
℃
)
E01
Communication
between operation
panel and indoor
PCB or outdoor PCB
failure
Compressor stops
Communication failure between operation panel and the
indoor or outdoor PCB. Check the cable connection in
between. Check whether the last three switches on
outdoor power PCB are set to 001; whether last three
switches on indoor PCB are set to 001. Unit recovers
when communication recovers.
E02
Outdoor power PCB
and driver PCB
communication
failure
Compressor stops
Check the communication cable between outdoor power
PCB and driver PCB. Check whether outdoor power PCB
and driver PCB is broken.
E03
Compressor phase
current failure
(open/short circuit)
Compressor stops
Check whether the power cable to compressor is broken
or short-circuit.
E04
Compressor phase
current overload
(over current)
Compressor stops
Check whether the power cable to compressor is broken
or short-circuit.
E05
Compressor driver
failure
Compressor stops
Check whether compressor drive PCB is broken, or cable
to compressor is wrong connected.
E06
Module VDC over
high/low voltage
failure
Compressor stops Input voltage too high or too low.
E07 AC current failure Compressor stops
Check the current to outdoor unit, and compare it with the
unit current shown on the operation panel. If the difference
is not big, check whether the system has enough
refrigerant (more likely it is not enough refrigerant that
caused this abnormal low current). If the difference is big,
