Possible causes
Solutions
AL05
Low-pressure fault on the
cooling circuit
Evaporator clogged or obstructed.
Clean the evaporator and remove any
obstacles in front of the evaporator.
Ventilated air fault.
Check that the fan is operating
correctly.
Cooling fault.
Call a qualified technician.
AL06
Heating water flow fault
No flow or low flow rate in the dehumidifier
circuit.
No alarm (shunt between terminals 20-21).
AL07
Phase sequence fault (on
three-phase models only)
Failure to correctly observe the cabling on
the appliance supply voltage terminal.
Invert the phases on the supply voltage
terminal (appliance disconnected from the
power supply).
Electricity provider has changed the
sequence of the phases.
Call a qualified technician, who will
contact the electricity provider to find out
if any changes have been made to your
installation.
Temporary disconnection of the power
supply to one or more phases.
AL09
Antifreeze
Pool water temperature inside the
condenser (ST1) too low (≤ 0 °C).
Make sure filtration is running properly
(if defective, drain out the condenser, to
prevent from icing).
AL10
Operating limit
(pool heating)
Outside temperature is too low < -8°C.
Condition has an impact on the appliance
cooling cycle. Only the electric heater is
heating the dehumidifier circuit.
Wait until the outside temperature rises (>-
8°C) to restart the cooling cycle, especially
for pool heating.
AL11
Defrosting
The sensor on the evaporator (ST3) has
reached a temperature reading of -5°C for
60 seconds. Defrost mode is required.
Wait for the defrost cycle to end.
AL12
RTC discharged/broken
• The appliance has remained
disconnected from the power supply for
more than 72 hours = RTC discharged
•
RTC broken
• Reconnect the appliance power supply
and update the date and time (see
§”2.3.5 Adjusting the heat pump timer
(RTC)”).
