Malfunction
Input current over
high protection.
Error
code
1. The compressor current is too large
instantaneously
2. Wrong connection for compressor
phase sequence
3. Compressor accumulations of liquid
EE07
and oil lead to the current becomes
larger
4. Compressor or driver board damaged
5. The water flow is abnormal
6. Power fluctuations within a short time
1. Signal wire is not well connected or
damaged
EE08
2. Controller failure
3. Driving failure
1. Poor connection of communication
wire
EE09
2. PCB failure
3. The wire is damaged
1. Line voltage is too high
EE10
2. Driver board is damaged.
1. Data mistake
2. Wrong compressor phase connection
3. Compressor liquid and oil
accumulation lead to the current
EE11
becomes larger
4.Poor heat dissipation of drive module
or high ambient temperature
5. Compressor or driver board damaged
1. Mother line voltage is too low
EE12
2. Driver board is damaged.
Error
code
1. The compressor current is too large
momentary

Solution
1.Check if the power in the normal range
2. Check the compressor
3. Check the compressor phase
4. Check the phase sequence connection
5. Check the waterway system and
filtration pump
6. Check mains power input
1. Stop the power supply and restart.
Re-connect the signal wire or replace a
new one
2. Check the controller or replace a new
one
3. Check the driving system or update it.
1. Stop the power supply and restart.
2. Reconnect the communication wire or
replace a new one
3. Check the wirings according to the
electric diagram
4. Replace a new PCB
1. Check whether the power supply is
normal
2. Change driver board or main board
1. Program error, turn off electricity
supply and restart after 3 minutes
2. Check compressor sequence
connection
3. Check the pressure of system by
pressure gauge
4. Check if the ambient and water
temperature is over high
5. If it is the refrigration system failure,
send it to the service center
6. Change driver board
1. Check if the power supply is in the
normal range
2. Change driver board
Solution
1. Check the compressor if it works
normally
2. Check the waterway system
3. Check if the power is in the normal
range
4. Check if the reactor is used correctly.
