Problem Possible cause 1
st
solution 2
nd
solution
Probable accumulation of
condensation. See
Paragraph 4.3.
Put the heat pump in
standby, see Paragraph
5.2.2, if the leak stops, this
is normal condensation.
Water leaks from the heat
pump.
Possible water leak from
the water exchanger or from
hydraulic unit connection
devices. See Figure 1
and/or Figure 5.
Tighten the fastening nut,
for an example, see Figure
5.
Insufficient water flow
Increase water flow in the
hydraulic circuit that
supplies the heat pump.
Error message EE b is
displayed.
Flow sensor incorrectly
connected or defective.
Check connections and
replace if necessary.
Replace the control board.
Ambient temperature under
-15 [°C]. See Paragraph
5.2.7.
Wait until ambient
temperature rises to start
the heat pump.
Error message EE c is
displayed.
Ambient temperature lower
than minimum working
temperature. See
Paragraph 5.2.7.
Set minimum working
temperature again, see
Paragraph 5.2.7, or wait
until ambient temperature
rises to start the heat pump.
Error message EE d is
displayed.
Functional parameter
changes. Parameter 9 is not
set to 0.
Set correct parameter
values to 1. See Paragraph
5.2.13.7.
Replace the control board.
See Figure 9.
The heat pump does not
work

and error message
EE 1 is displayed.
Pool temperature sensor
incorrectly connected or
defective.
Check the sensor
resistance value, see
Paragraph 6.1.1, and
replace if necessary.
Replace the control board.
See Figure 9.
The heat pump does not
work

and error message
EE 2 is displayed.
Ambient temperature
sensor incorrectly
connected or defective.
Check the sensor
resistance value, see
Paragraph 6.1.1, and
replace if necessary.
Replace the control board.
See Figure 9.
The heat pump is running

sensor incorrectly
connected or defective.
Check the sensor
resistance value, see
Paragraph 6.2.1, and
replace if necessary.
Replace the control board.
See Figure 9.
Automatic defrost did not
run correctly.
Increase water flow at pump
inlet.
The heat pump is running

and error message EE 4 is
displayed.
Plate heat exchanger
temperature sensor
incorrectly connected or
defective.
Check the sensor
resistance value, see
