Value
Default
r0
Temperature difference
compared to main SETPOINT
0.2 – 10 °C
2 °C
d0
Defrost interval
(hours)
If d0 = 0 cyclical defrosts Off
0 – 24 hours
4 hours
d2
End-of-defrost setpoint.
Defrost is not executed if the temperature read by the defrost sensor is greater than
d2. (If the sensor is faulty defrosting is timed)
-35 – 45 °C
15 °C
d3
Max defrost duration
(minutes)
1 – 240 min
25 min
d7
Drip duration
(minutes)
At the end of defrost the compressor and fans remain at standstill for time d7, the
defrost LED on the front panel flashes.
0 – 10 min
0 min
F5
Fan pause after defrost
(minutes)
Allows fans to be kept at standstill for a time F5 after dripping. This time begins at the
end of dripping. If no dripping has been set the fan pause starts directly at the end of
defrost.
0 – 10 min
0 min
A1
Minimum temperature alarm
Allows user to define a minimum temperature for the room being refrigerated. Below
value A1 an alarm trips: the alarm LED flashes, displayed temperature flashes and the
buzzer sounds to indicate the problem.
-45 – (A2-1) °C
-45 °C
A2
Maximum temperature alarm
Allows user to define a maximum temperature for the room being refrigerated. Above
value A2 an alarm trips: the alarm LED flashes, displayed temperature flashes and the
buzzer sounds to indicate the problem.
(A1+1) – 99 °C
99 °C
tEu
Evaporator sensor temperature display
(displays nothing if dE =1)
Evaporator temperature
read only
Variables
Meaning
Value
Default
F3
Fan status with compressor off
0 = Fans run continuously
1 = Fans only run when compressor is working
2 = Fans disabled
1
F4
Fan pause during defrost
0 = Fans run during defrost
1 = Fans do not run during defrost
1
F6
Evaporator fans activation for air recirculation.
The fans activate for a time defined by F7 if they have not started working for the F6
time. If activation time coincides with the defrosting time, end of defrosting is awaited.
0 – 240 min
0 = (function not activated)
0 min
F7
Evaporator fans duration for air recirculation.
Fans working time for F6
0 – 240 sec
10 sec
dE
Sensor presence
If the evaporator sensor is disabled defrosts are carried out cyclically with period d0:
defrosting ends when an external device trips and closes the remote defrost contact or
when time d3 expires.
0 = evaporator sensor present
1 = no evaporator sensor
0
d1
Defrost type
, cycle inversion (hot gas) or with heater elements
0 = heating element
1 = hot gas
2 = heater with temperature control
0
dPo
Defrost at Power On
0 = disabled
1 = defrost at power-on (if possible)
0
dSE
Smart defrost
0 = disabled
1 = enabled
0
dSt
Smart defrost Setpoint (if dSE=1)
The counting of the time between the defrost is incremented only if the compressor is
ON and the evaporator temperature is less than dSt.
