Problem Error codes Description Solution
Water inlet sensor defect. P01
The sensor is open or presents a
short-circuit.
Verify or replace the sensor.
Water outlet sensor defect. P02
The sensor is open or presents a
short-circuit.
Verify or replace the sensor.
De-icing sensor defect. P05
The sensor is open or presents a
short-circuit.
Verify or replace the sensor.
Exterior temperature sensor defect. P04
The sensor is open or presents a
short-circuit.
Verify or replace the sensor.
Compressor aspiration sensor defect P07
The sensor is open or presents a
short-circuit.
Verify or replace the sensor.
The inlet and outlet difference in
water temperature is too high.
E06
Water flow volume is insufficient,
water pressure difference is too low/
too high.
Verify the water flow, or system
obstruction.
Antifreeze Protection
Cold mode
E07 Water outlet quantity is too weak.
Verify the water flow, or the outlet
water temperature sensor.
Level 1 antifreeze protection E19
Air temperature or water inlet
temperature is too weak.
Level 2 antifreeze protection E29
Air temperature or water inlet
temperature is still too weak.
High pressure protection E01
Pressure of the refrigeration circuit
is too high, or the water flow is too
low, or the coil is obstructed or the
air flow is too weak.
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.
Low pressure protection E02
Refrigeration circuit pressure is too
weak, or air flow is too weak or the
coil is obstructed.
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.
Flow detector defect E03
Water flow is insufficient or the
detector is in short-circuit or
defective.
Verify the water flow, verify the
filtration pump and the flow detector
to see if they have any possible
problems.
Communication problem E08
Problem with the LED controller or
the PCB connection. Check the connection of the NET and
NET 1 cables.
The compressor will not start E08
Phase missing or phase order
incorrect
check that the 3 phases are present
modify the phase order at the heat
pump’s electrical connection terminal
block
