Error codes Description
The sensor is open or presents
P01
a short-circuit.
The sensor is open or presents
P02
a short-circuit.
The sensor is open or presents
P05
a short-circuit.
The sensor is open or presents
P04
a short-circuit.
Water flow volume is
E06 insufficient, water pressure
difference is too low/too high.
Water outlet quantity is too
E07
weak.
Air temperature or water inlet
E19
temperature is too weak.
Air temperature or water inlet
E29
temperature is still too weak.
Pressure of the refrigeration
circuit is too high, or the water
E01 flow is too low, or the coil is
obstructed or the air flow is
too weak.
Refrigeration circuit pressure
E02 is too weak, or air flow is too
weak or the coil is obstructed.
Water flow is insufficient or the
E03 detector is in short-circuit or
defective.
Problem with the LED
EE8 controller or the PCB
connection.
Phase missing or phase order
incorrect
Certain operations must be carried
out by an authorized technician.
Verify or replace the sensor.
Verify or replace the sensor.
Verify or replace the sensor.
Verify or replace the sensor.
Verify the water flow, or system
obstruction.
Verify the water flow, or the
outlet water temperature sensor.
Verify the high pressure switch
and the refrigeration circuit
pressure.
Verify the water or air flow.
Verify that the flow switch is
working correctly.
Verify the water inlet/outlet valve
openings.
Verify the by-pass setting.
Verify the low pressure switch
and the refrigeration circuit
pressure to determine if there
is a leak.
Clean the coil surface.
Verify the fan rotation speed.
Verify that there is free air flow
to the coil.
Verify the water flow, verify the
filtration pump and the flow
detector to see if they have any
possible problems.
Verify the cable connection.
check that the 3 phases are
present
modify the phase order at
the heat pump's electrical
connection terminal block
