VARIABLES
MEANING
VALUES
DEFAULT
dtC
HOT temperature differential
referred to main SETPOINT.
It is expressed in absolute value and defines the
temperature hysteresis for HOT referred to temperature
SETPOINT.
(dtn+0.2) ÷ 10 °C
2,0 °C
dtF
COLD
temperature
differential
referred
to
main
SETPOINT. It is expressed in absolute value and defines the
temperature hysteresis for COLD referred to temperature
SETPOINT.
(dtn+0.2) ÷ 10 °C
2,0 °C
dtn
NEUTRAL temperature area
referred to main SETPOINT.
Cold and hot are not activated in neutral area; it
symmetrically includes an upper part (hot) and a lower part
(cold) respect to temperature SETPOINT.
dtF>dtn ÷ 0 °C
dtC>dtn ÷ 0 °C
0,0 °C
dUU
HUMIDIFICATION differential
referred to main SETPOINT.
It is expressed in absolute value and defines the
humidification hysteresis referred to humidity SETPOINT.
(dUn+1) ÷ 10
rH%
5 rH%
dUd
DEHUMIDIFICATION differential
referred to humidity
SETPOINT. It is expressed in absolute value and defines the
dehumidification hysteresis referred to humidity SETPOINT.
(dUn+1) ÷ 10
rH%
5 rH%
dUn
NEUTRAL humidity area
referred to main SETPOINT.
Humidification and dehumidification are not activated in
neutral area; it symmetrically includes an upper part
(humidification) and a lower part (dehumidification) respect
to humidity SETPOINT.
dUU>dUn ÷ 0

0 rH%
d4
Defrosting interval
(hours). d4=0 disables defrosting
0 ÷ 24 hours
0 hours
d5
Defrosting maximum duration
(minutes)
1 ÷ 60 min
10 min
d6
End defrosting setpoint
.
Defrosting is not carried out if the temperature read by the
defrosting probe is higher than value
d6.
(In case of faulty probe, timed defrosting is carried out)
-35 ÷ 45 °C
15°C
d7
Dripping duration
(minutes)
At the end of defrosting, the compressor and the fans remain
still for the
d7
set time, the defrosting icon flashes.
