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.

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

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.
