/ Swimming Pool Heat Pump Inverboost C
Malfunction
Error code
Reason
Solution
VDC voltage too
high protection
EE10
1. Line voltage is too high
2. Driver board is damaged.
1. Check whether the power
supply is normal
2. Change driver board or main
board
IPM module
protection
EE11
1. Data mistake
2. Wrong compressor phase
connection
3. Compressor liquid and oil
accumulation lead to the
current becomes larger
4. Poor heat dissipation
of drive module or high
ambient temperature
5. Compressor or driver
board damaged
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
VDC voltage too low
protection
EE12
1. Mother line voltage is too
low
2. Driver board is damaged.
1. Check if the power is in the
normal range
2. Change driver board
Input current over
high protection.
EE13
1. The compressor current is
too large momentary
2. The water flow is abnormal
3. Power fluctuations within a
short time
4. Wrong reactor
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.
IPM module thermal
circuit is abnormal
EE14
1. Output abnormity of IPM
module thermal circuit
2. Fan motor is abnormal or
damaged
3. Fan blade is broken
1. Check if the motor speed
is too low or fan motor is
damaged, replace it by a new
one.
2. Replace a new driver board
3. Change the fan blade if it is
broken
IPM module
temperature too
high protection
EE15
1. Output exception of IPM
module thermal circuit
2. Fan motor is abnormal or
damaged
3. Fan blade is broken
4. The screw on driver board
is loose
1. Check the main board or
replace the driver board
2. Check if the motor speed
is too low or fan motor is
damaged, replace it by a new
one if any failure.
3. Change the fan blade if it is
broken
4. Check the screw on driver
board
