7.1.3.12 Errors
Pr1
Upper boiler probe error
Solutions:
- Check
that
corresponds
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
evaporator probe.
- The appliance stops working
When the cause of the error
disappears,
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:
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
operation,
activated.
