5.10 List of Level 2 variables
(installer level)
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 defrosting
0 = Fans run during defrost
1 = Fans do not run during
defrost
1
F6
Evaporator fans activation for air recirculation.
The fans are activated for a time defined by F7 if they
have not started operating for the time F6. If the time
of activation coincides with the defrost phase,
the defrost end is still awaited.
0 – 240 min
0 = (function not activated)
0 min
F7
Duration of activation of the evaporator fans for air
recirculation
Fans working time for F6
0 – 240 sec
10 sec
dE
Evaporator probe 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
Variables Meaning
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 defrost is stopped on time set by the d3
parameter)
-35 – 45 °C
15 °C
d3
Max defrost duration
(minutes)
1 – 240 min
25 min
d7

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)

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
