d 2 -99 +99.9 (*) +2.0 defrost stopping setpoint
It is significant exclusively if the parameter /Ab has value 1, it establishes the temperature to
which a defrost gets stopped and it is referred to the evaporator probe.
d 3
0 99 min. 30 defrost maximum length
It establishes the defrost maximum length.
Passed the defrost maximum length from the moment in which the instrument activates a
defrost cycle, if the temperature read by the evaporator probe is below the setpoint established
with the parameter d 2 the defrost ends.
If the parameter d 3 has value 0 the instrument never presents a request of a defrost cycle.
d 4
0 1 --- 0 defrost cycle at the instrument start
It establishes if the instrument automatically must present a request of a defrost cycle at the
moment of the instrument start, as indicated:
0 = inactive
1 = the instrument automatically presents a request of a defrost cycle at the moment of the
instrument start.
d 5 0 99 min. 0 delay to a defrost cycle activation from the instrument
start
If the parameter d 4 has value 0 and if the parameter d E has value 0, it establishes a time
interval to add to the interval established with the parameter d 0; the value so obtained estab-
lishes the time interval that pass from the moment of the instrument start to the moment in
which the instrument automatically presents the following request of a defrost cycle.
If the parameter d 4 has value 0 and if the parameter d E has value 1, it establishes a time
interval to add to the interval established with the parameter d 0; the value so obtained estab-
lishes for which time interval the compressor output must be remained activated from the
moment of the instrument start in order that the instrument can automatically activate the
following defrost cycle.
If the parameter d 4 has value 0 and if the parameter d E has value 2, it establishes a time
interval to add to the interval established with the parameter d 0; the value so obtained estab-
lishes for which time interval the temperature read by the evaporator probe must be remained
below the setpoint established with the parameter d F from the moment of the instrument start
in order that the instrument can automatically present the following request of a defrost cycle.
If the parameter i 0 has value 1 it establishes the delay with which the instrument presents a
request of a defrost cycle from the moment of the multifunction digital input activation.
If the parameter d 4 has value 1 it establishes the delay with which the instrument automatically
presents a request of a defrost cycle from the moment of the instrument start.
A manual presentation of a request of a defrost cycle during the count of the delay established
with the parameter d 5 clears the delay.
d 6
0 1 --- 1 locking of the displayed temperature from a defrost cy-
cle activation
It establishes if to lock the displayed temperature from the moment in which the instrument
activates a defrost cycle, as indicated:
0 = inactive
1 = if in the moment in which the instrument activates a defrost cycle the temperature read
by the cabinet probe is below the value obtained adding the working setpoint to the
hysteresis (differential) established with the parameter r 0 the value so obtained
establishes the temperature above which the locking of the displayed temperature gets
activated, if in the moment in which the instrument activates a defrost cycle the
temperature read by the cabinet probe is above the value obtained adding the working
setpoint to the hysteresis (differential) established with the parameter r 0 every value to
which the temperature read by the cabinet probe increases establishes the temperature
above which the locking of the displayed temperature gets activated, except if the
increasing happens below the value obtained adding the working setpoint to the
hysteresis (differential) established with the parameter r 0 when it is worth what saw in
the previous case; the unlocking of the displayed temperature happens from the
moment of a defrost cycle end when the temperature read by the cabinet probe falls
below the temperature above which the locking of the displayed temperature gets
activated (if during a defrost cycle the working setpoint gets modified it is worth what
saw in the previous cases except that the unlocking of the displayed temperature
happens from the moment of a defrost cycle end).
A temperature alarm activation that happens during a locking of the displayed temperature
gives the unlocking of the displayed temperature.
d 7
0 15 min. 2 dripping length
It establishes the dripping length.
d 9
0 1 --- 0 disabling times to the compressor output activation over-
ride
It is significant exclusively if the parameter d 1 has value 1, it establishes if to clear the disabling
times to the compressor output activation in the moment in which the instrument presents a
request of a defrost cycle, as indicated:
0 = inactive
1 = in the moment in which the instrument presents a request of a defrost cycle the
disabling times to the compressor output activation get cleared.
d E 0 3 --- 0 defrost interval kind of count
It establishes the defrost interval kind of count that the instrument must manage, as indicated:
0 = periodic (the defrost interval establishes the time interval that pass from the moment of
the instrument start or from the moment in which the instrument presents a request of
a defrost cycle to the moment in which the instrument automatically presents the
following request of a defrost cycle)
1 = for sum of the lengths of the compressor output activation (the defrost interval
establishes for which time interval the compressor output must be remained activated
from the moment of the instrument start or from the moment in which the instrument
activates a defrost cycle in order that the instrument can automatically activate the
following defrost cycle)
2 = for sum of the lengths of the persistence of the temperature read by the evaporator
probe below the setpoint established with the parameter d F (the defrost interval
establishes for which time interval the temperature read by the evaporator probe must
be remained below the setpoint established with the parameter d F from the moment of
the instrument start or from the moment of a defrost cycle end in order that the
instrument can automatically present the following request of a defrost cycle
2 = real time (the instrument automatically presents a request of a defrost cycle at every
time established with the parameters Hd1, Hd2, Hd3, Hd4, Hd5 and Hd6, according
with the real hour and minute established with the label rtc, see the chapter REAL HOUR
AND MINUTE).
d F -99 +99.9 (*) 0.0 defrost interval count enabling setpoint
It is significant exclusively if the parameter d E has value 2, it establishes the temperature above
which the defrost interval count gets disabled and it is referred to the evaporator probe.

lishes the temperature above which the upper temperature alarm gets activated and it is re-
ferred to the cabinet probe.
