Defrosting
Pressing this area enables selection of a manual defrosting cycle, which is started up by pressing area
. When
the cycle starts up the following page is displayed.
Defrosting can also be done automatically at time intervals set by parameter d0, provided this value is not set at 0.
Regardless of how have been started up, defrosting cycles are managed by the following parameters.
d0
Interval between two consecutive defrosts
d1
Type of defrost
d2
Evaporator temperature to end defrost (can be set if P4 is set to 1)
d3
Defrost duration
d4
Defrost start-up at the beginning of a blast chilling/blast-freezing cycle
d5
Defrost start-up delay from the start of conservation after blast chilling/blast-freezing
d7
Drip duration
d15
Minimum compressor switch-on duration for starting hot gas defrost
d16
Pre-drip duration (can be set if hot gas defrost is selected)
The type of defrost can be selected by parameter d1. There are four ways of performing a defrost cycle.
d1=0
Electric defrost
d1=1
Hot gas defrost
d1=2
Air defrost
d1=3
Air defrost with door open
An automatic defrost cycle is activated at the start of a blast chilling/blast-freezing cycle if d4=1. Regardless of the
parameter d4 value, automatic defrost is activated with a delay as compared to the beginning of the conservation
phase set by parameter d5.
If the evaporator probe is present when a defrost cycle is to be activated, this only starts if the temperature indicated
by the evaporator probe is lower than the value of parameter d2.
