Pr1 Error in prob e in upper part of the b oiler
Solutions:
- Check that the type of probe is in conformity
with parameter P0 settings;
- Check the probe is intact;
- Check the equipment-probe connection;
- Check the temperature of the upper part of
the boiler.
Main consequences:
- The equipment stops working.
Pr2 Error in prob e in lower part of the b oiler

8.1.3.13 Defrosting
Defrosting can be enabled in the following way:

Automatically, when the temperature of the
evaporator is below that established in parameter
d17 (only if P4 has a value other than 0);
In any case, between one defrosting procedure and
another, the compressor must have been left switched
on for a period either longer than or equal to d18
minutes. Otherwise the request to enable the defrosting
procedure will not be accepted.
If P4 = 1, d2 represents the temperature of the
evaporator, above which the defrosting procedure is
terminated. Vice versa, if P4 = 0 or P4 = 2, parameter
d2 is not taken into consideration.
If during the defrosting procedure the evaporate or
probe is above the threshold set by means of
parameters d2 and P4 = 1, the request to enable the
defrosting procedure is not accepted.
Installation and user manual
The defrosting procedure consists of three stages:

Defrosting stage: Parameter d3 establishes the
maximum duration of the stage.
Output status:

The compressor is active if d1 = 1,otherwise it is
switched off;

The defrosting relay is active if d1 = 0 or d1 =
1,otherwise it is switched off;

The fans are switched on if d1 = 2, otherwise they
are switched off.

Dripping stage: Parameter d7 establishes the
duration of the stage.
Output status:
-
The compressor is switched off;
- The defrosting relay is active if d1 = 0 or d1 =
1,otherwise it is switched off;
-
The fans are switched off.

Drying stage.
Parameter d16 establishes the duration of the
stage. Output status:

The compressor acts according to parameter d8;
- The defrosting relay is active if d1 = 0 or d1 =
1,otherwise it is switched off;
-
The fans are switched off.
If the "Anti-Legionella" or the "Overboost"
functions are in progress, the defrosting
procedure will not be enabled.
