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 error
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.

Setting the day and time
Make sure that the keypad is not locked
(section 7.1.3.3) and that there are no
other advanced procedures running;
Press and release the
button: the first
available code is shown on the display;
Press and release the
button or the
button until you see “rtc”;
The day is shown in the format 1-7 (1 =
Monday, etc.).
