P01
circuited.
The sensor is open or has short-
P02
circuited.
The sensor is open or has short-

Refrigerating circuit pressure too
E01 high or water flow too low or coil
obstructed or air flow too weak.
Refrigerating circuit pressure too
E02 low or air flow too weak or coil
obstructed.
Insufficient water flow or sensor
E03
short-circuited or faulty
Insufficient water flow volume,
E06 water pressure difference too
low/too high.
E07 Water outlet quantity too low.
LED controller or PCB connection
E08
fault.
Air and inlet water temperature
E19
too low.
Air and inlet water temperature
E29
even lower.
Certain operations must be performed
by an approved engineer.
Check or replace the sensor.
Check or replace the sensor.
Check or replace the sensor.
Check or replace the sensor.
Check the high pressure switch
and the refrigerating circuit
pressure.
Check the water or air flow. Check
the flow controller is working
properly.
Check that the water inlet/outlet
valves are opening.
Check the by-pass settings.
Check the low pressure switch and
the refrigerating circuit pressure to
see if there is a leak.
Clean the coil surface.
Check the fan rotation speed.
Check the free circulation of air
through the coil.
Check the water flow, check the
filtration pump and flow sensor for
any faults.
Check the water flow or for a
system obstruction.
Check the water flow rate or the
outlet water temperature sensor.
Check the wiring.
Turn off the heat pump and drain
the capacitor. Freezing risk.
