16.1 Alarms resolution
Alarm code Cause Solution proposed
ALB01 Condensation high pressure, the most of times this alarm is
caused by the too high set of water produced both in heating
and in DHW. Other more frequent reasons for this are: the
wrong position of the regulation probles (B2 and B3) respect
to the flow of the unit and the insufficient flow of the water to
the plate heat condensator.
1) put the probes B2 and/or B3 at the same height respect
to the flow accumulation input of the machine.
ALB02 Vedi ALB01 See ALB01
ALB03 The low pression from transducer can be connected to
the internal dynamic of the machine. But it could also be a
symptom of transducer malfunction or a refrigerant loss.
If the alarm is frequent 2/3 times consecutive in 4-6 hours
survey the unit with a leak detector and contact the service.
ALC03 Alarm envelope, the compressor is gone out from his work
field. In this case the reasons are several and listable.
We suggest at first to evaluate the use of the unit that
can be incoherent with the working field of the unit, for
example, operation DHW with external temperature too
high. Please, refer to the section “operative zone allowed”
of this guide.
ALC04 The compressor can’t create a minimum delta of pressure in
a certain interval of time the reason can be the inertia of the
system and the proximity between the temperature of air and
water
If it happens occasionally it is a simple reporting non serious
nature allowing the unit to continue to operate.
ALP03 Lack of flow in the hydraulic circuit, caused by the air present
in the system, solid particles o excessive pressure losses
Vent the system of all the air present, regular cleaning of the
system. Avoid excessive losses of pressure in the hydraulic
circuit, in particular avoid restrictions of the system.
ALW03 Caused by air currents cooling the coil finned during the
defrosting process
Study a different position of the machine or hinder the
direct wind through the unit.
ALD04 Alarm that depends on the internal dynamics of the machine Contact the assistance
ALD06 Alarm that depends on the internal dynamics of the machine Survey the unit with a leak detector and contact the service
ALD07 Alarm that depends on the internal dynamics of the machine Contact the service
ALL01 Lack of communication between inverter and electronic
board caused by power surges and minor power current or by
electromagnetic fields that trouble the network
Control the counter that supplies the machine to avoid to
overload it, check the domestic line, avoid electromagnetic
fields in the nearby
ALL02 Lack of communication between inverter and electronic
board caused by power surges and high power current or by
electromagnetic fields that trouble the net
Check the counter that supplies the machine to avoid the
overload, ccheck the domestic line, avoid electromagnetic
fields in the nearby.
Then contact the service
