Input current over high
protection.
1. The compressor current is too large
instantaneously
2. Wrong connection for compressor phase
sequence
EE07 3. Compressor accumulations of liquid 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
EE11 lead to the current 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.
1. The compressor current is too large
momentary
EE13 2. The water flow is abnormal
3. Power fluctuations within a short time
4. Wrong reactor
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.
4. 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
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.
