Error codes Description
Pressure of the refrigeration
circuit is too high, or the water
EE1 flow is too low, or the coil is
obstructed or the air flow is
too weak.
Refrigeration circuit pressure
is too weak, or air flow is too
EE2
weak or the coil is obstructed.
Water flow is insufficient or the
detector is in short-circuit or
EE3
defective.
Problem with the connection to
EE4
PCB PROT2

PP1
a short-circuit.
The sensor is open or presents
PP2
a short-circuit.
The sensor is open or presents
PP3
a short-circuit.
The sensor is open or presents

Problem with the LED
controller or the PCB
888
connection.
Certain operations must be carried
out by an authorized technician.
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.
Check the connection
Verify or replace the sensor.
Verify or replace the sensor.
