8.1.3.13 Defrosting
Defrosting is enabled:
•
Automatically, when the temperature of the
evaporator is below the temperature established in
parameter d17 (only if P4 has a value other than 0);
In any case, the compressor must have been left
switched on for a period either longer than or equal
to d18 minutes between two defrosting procedures.
Otherwise the request to enable the defrosting
procedure will not be accepted.
If P4 = 1, d2 represents the temperature of the
evaporator. The defrosting procedure terminates
when the temperature exceeds the temperatures
represented by d2.
If P4 = 0 or P4 = 2, parameter d2 is not taken into
consideration.
If during the defrosting procedure the evaporator or
thermistor is above the threshold set by parameters
d2 and P4 = 1, the request to enable the defrosting
procedure is not accepted.
•
The parameter d3 establishes the maximum
duration of the stage.
•
When defrosting mode is on, the heating
element will commence operation
If the “Anti-Legionella” or the “Overboost”
functions are in progress, the defrosting
procedure cannot be enabled.
