MEANING
DEF.
r0
Temperature differential in relation to principal
SET-POINT < Range: 0,2 ÷ 10,0°C >
Expressed in absolute values and defines hysteresis
(positive if mOd=0 or negative if mOd=1) of
temperature in relation to SET POINT.
2,0
d0
Defrosting interval
< Range: 0 ÷ 24 hours >
If d0=0 defrosting is excluded.
4
dd2
Delayed defrost for the second evaporator
<Range: 0 ÷ 10 sec > - 0 = contemporary start
The defrost process of the second evaporator starts
dd2 seconds after the defrost process of the first
evaporator. This avoids overloading the electrical
system during the defrost process in the event of
limited power. When dd2=0, defrost processes 1
and 2 start simultaneously.
dd2 is forced to 0 if d1 = 1 or 2. (Cycle inversion
defrosting)
d21
Defrosting 1 end set point
< Range:-35 ÷ 45°C >
Defrosting 1 is not performed if the temperature
read by the defrosting probe is higher than value
d21. (In the event of a defective probe, defrosting 1
is performed on a time basis.)
15
d22
Defrosting 2 end set point
< Range:-35 ÷ 45°C >
Defrosting 2 is not performed if the temperature
read by the defrosting probe is higher than value
d22. (In the event of a defective probe, defrosting 2
is performed on a time basis.)
15
d31
Maximum defrosting time
< Range: 1 ÷ 240 min >
25
d32
Maximum defrosting time
< Range: 1 ÷ 240 min >

remain inactive for the set period of time d7 and the
defrosting LED on the front of the board flashes.
0
F5
Fan stop after defrosting < Range: 0 ÷ 10 min >
Keeps fans inactive for a period of time F5 after
dripping. This period is timed from the end of
dripping. If dripping is not set, the fans pause directly
after defrosting.

alternating with the temperature on the display, as
well as the flashing alarm icon.
-45
A2
Maximum temperature alarm
< Range: (A1+1) ÷ 99°C >
Absolute temperature referred to by the ambient
probe above which, following the ALD delay, the
HIGH temperature alarm is triggered, activating the
buzzer (if present) and showing the letters EH
alternating with the temperature on the display, as
well as the flashing alarm icon. When the alarm is
reset the alarm icon remains on without flashing to
indicate that the event occurred, until the UP key is
pressed.

min. etc.). The winking point (.) shows that it is
displayed a time and not a temperature.
