sensor failure
The Heat Pump will continue to work, but less efficiently (up to 5%).
Call customer
service.
F18
Indoor coil temp.
sensor failure
The Heat Pump will continue to work normal, except for cooling mode.
Call customer
service.
F21
Mixture valve 1
temperature sensor
failure

F27
Indoor EEPROM failure
The Heat Pump will continue to work, but less efficiently
(up to 5%).
Call customer
service.
F28
Water pump PWM
signal feedback failure
The Heat Pump will continue to work, but less efficiently
(up to 5%).
/
F29
Mixture valve 1 failure
The Heat Pump will continue to work, except for the first heating
circuit. It will start again to heat the first heating circuit when the
temperature on TV1 falls 1°C below set point.
/
F30
Mixture valve 2 failure
The Heat Pump will continue to work, except for the second heating
circuit. It will start again to heat the first heating circuit when the
temperature on TV1 falls 1°C below set point.

S01
Indoor anti-freezing
protection in cooling
Clean the cleaning element (filter), check water pressure, water set
temperature for cooling, hand valve is partly or totally closed.
/
S02
Too small water flow
rate
Clean the cleaning element (filter), check water pressure, hand valve is
partly or totally closed.
/
S03
Water flow switch
failure
Call customer service.
/
S04
Communication failure
Call customer service.
/
S05
Serial port connect
error
Call customer service.

S06
Water outlet Temp. too
low protection in
cooling
Clean the cleaning element (filter), check water pressure, hand valve is
partly or totally closed, cooling set temperature is set too low.
/
S07
Water outlet Temp. too
high protection in
heating/hot water
Compressor stops if water outlet is higher than 57
℃
in heating or hot
water mode. Check whether temperature sensor Tc and Tw is OK and
well connected; whether set water temperature too high; whether
system flow rate too small.
/
S08
Unit defrosting failure
Clean the cleaning element (filter), check water pressure, hand valve is
partly or totally closed. Moist screed can also cause this error.
/
S09
Water outlet Temp. too
low protection in
defrosting
Clean the cleaning element (filter), check water pressure, hand valve is
partly or totally closed. Moist screed can also cause this error.
/
S10
Too small water flow
rate failure
Clean the cleaning element (filter), check water pressure, hand valve is
partly or totally closed, temperature setting is set to high. Air in the
system can cause this error.
/
S11
Indoor anti-freezing
failure in cooling
Clean the cleaning element (filter), check water pressure, water set
temperature for cooling, hand valve is partly or totally closed.
/
S12
Floor curing function
failed to finish
Too much moisture in the floor, house without insolation, low ambient
temperatures.
