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.
-30 – 30 °C
1 °C
dFd
Display viewing during Defrost
0 = current temperature
1 = temperature at the
start of the defrost
2 = “DEF”
1

subsequent
switching on of the compressor.
