Errors
Pr1
Upper boiler probe error
Solutions:
-
Check that the type of probe corresponds to
the setting under parameter P0;
-
Check that the probe is integral;
-
Check the connection between the appliance
and the probe;
-
Check the temperature of the upper part of
the boiler.
Main consequences:
-
The appliance stops working.
Pr2
Lower boiler probe error
Solutions:
-
As above only in relation to the probe for the
lower part of the boiler.
Main consequences:
-
The appliance stops working.
Pr3
Evaporator probe error
Solutions:
-
As above only in relation to the evaporator
probe.
-
The appliance stops working.
When the cause of the alarm disappears, the
appliance resumes normal operation.
7.1.3.13
Defrosting
Defrosting is activated:
Automatically,
when
the
evaporator
temperature falls below the temperature set
under parameter d17 (only if P4 is not 0);
In any case, between one defrosting cycle and
the next, the compressor must have been on for at
least d18 minutes. Otherwise, the defrosting
request is not accepted.
If P4 = 1, d2 is the evaporator temperature above
which defrosting stops. Vice versa, if P4 = 0 or P4 =
2, the parameter d2 is not considered.
If, when defrosting, the evaporator probe is above
the threshold set under parameter d2 and
parameter P4 = 1, the defrosting request is not
accepted.
Defrosting is made up of the following stages:
Defrosting phase: parameter d3 determines
the maximum duration of this phase.
Output statuses:
-
Compressor active where d1 = 1,
otherwise off;
-
Defrost relay active where d1 = 0 or d1 = 1,
otherwise off;
-
Fans on where d1 = 2, otherwise off.
Dripping phase: parameter d7 determines the
duration
of
this
phase.
Output statuses:
-
Compressor off;
-
Defrost relay active where d1 = 0 or d1 = 1,
otherwise off;
-
Fans off.
Drying phase: parameter d16 determines the
duration of this phase. Output statuses:
-
Compressor according to parameter d8;
-
Defrost relay active where d1 = 0 or d1 = 1,
otherwise off;
-
Fans on.
If the Anti-legionella function or the
Overboost function is in operation,
defrosting is not activated.
