LIST OF 1ST-LEVEL VARIABLES
(User Level)
VARIABLES
MEANING
VALUES
DEFAULT
r0
Temperature differential
referred to the main SET-POINT.
Defines the hysteresis of the temperature referred to the SET-POINT.
0.2 ÷ 10.0 °C
2.0 °C
d0
Defrost interval
(hours)
With d0=0 and dFr=0 defrosts are excluded.
0 ÷ 24 hours
4 hours
d2
Defrost end set-point
.
Defrosting is not performed if the temperature read by the defrosting probe is
greater than the value d2.
(In case of faulty probe defrosting is performed on time)
-35 ÷ 45 °C
15°C
d3
Maximum defrost duration
(minutes)
1 ÷ 240 min
25 min
d7
Dripping duration
(minutes)
At the end of defrosting, the compressor and fans remain stationary for the
set time d7, the defrosting LED on the front of the panel flashes.
0 ÷ 10 min
0 min
F5
Fan pause
after defrosting (minutes)
Allows the fans to remain stationary for a time F5 after dripping. This time is
counted from the end of the dripping. If the dripping is not set, at the end of
defrosting the fans pause immediately.
0 ÷ 10 min
0 min
A1
Minimum temperature alarm
Absolute temperature referring to the ambient probe under which, once the
delay time Ald has elapsed, the low temperature alarm is activated, which
consists of activating the Buzzer (if present), the
EL
word alternating with the
temperature on the display and the flashing of the alarm presence icon.
When the alarm returns, the "alarm presence" icon remains on steady to
indicate the intervention until the UP key is pressed.
-45.0 ÷ (A2-1)
°C
-45.0°C
A2
Maximum temperature alarm
Absolute temperature referring to the ambient probe above which, once the
delay time Ald has elapsed, the high temperature alarm is activated, which
consists of activating the Buzzer (if present), the
EH
word alternating with
the temperature on the display and the flashing of the alarm presence icon.
When the alarm returns, the "alarm presence" icon remains on steady to
indicate the intervention until the UP key is pressed.
(A1+1) ÷ +99.0
°C
+99.0°C
dFr
Enable real-time defrosting of evaporators
With d0=0 and dFr=1 it is possible to set up to 6 real-time defrosts over a
day through the
dF1…dF6 parameters.
0 = disabled
1 = enabled
0
dF1…
dF6
Programming the evaporator defrost times.
You can set up to 6 times for defrost.
The time is in the form HH.M where HH represents the hour and M the tens
of minutes (Ex. 0=0 min; 1=10 min, etc.). The flashing dot (.) indicates that a
time is displayed and not a temperature.
00.0 ÷ 23.5

tdS
Start of day phase
00.0 ÷ 23.5
6.0
tdE
End of day phase
00.0 ÷ 23.5
22.0
