Parameter
Description
Values/Range
FnC
Fan operation mode: C-n= in parallel with compressor, OFF in defrosting. C-y= in
parallel with compressor, ON during defrosting. O-n= continuous mode, OFF during
defrosting. O-y= continuous mode, ON during defrosting.

O, n
O, y
Fnd
Fan delay after defrosting: time interval between end of defrosting and activation of
fans.
0...255 min
FCt
Temperature differential to prevent fan fluctuation, if the temperature difference
between the evaporator and the control probe is greater than the parameter FCt, the
fans are activated.
0.0°C...50.0°C
0°F...90°F
FSt
Fan stop temperature: temperature at which the fans are stopped.
- 50... 110°C
- 58...230°F
FHy
Fan restart differential: When the fans stop, they can only restart if the fan control
probe reaches the value FSt- FHy.
0.1°C...25.5°C
1°F...45°F
Fod
Fan activation time after defrosting: forces activation of fans for the indicated time.
During this time the compressor is switched off. This serves to expel warm air before it
starts to get cold again.
0...255 min
Fon
Fan time ON: with FnC= C_n or C_y, (fans in parallel with compressor). Sets the ON time
of the fans when the compressor is switched off. With Fon=0 and FOF ≠ 0 the fans are
always off, with Fon=0 and FOF=0 the fans are always off.
0...15 min
FOF
Fan time OFF: with FnC= C_n or C_y, (fans in parallel with compressor). Sets the OFF
time of the fans when the compressor is switched off. With Fon=0 and FOF ≠ 0 the fans
are always off, with Fon=0 and FOF=0 the fans are always off.

5.1.5 Alarms
Parameter
Description
Values/Range
rAL
Temperature alarm probe selection: selects the probe used for temperature alarm
signalling.
nP, P1, P2, P3
ALC
Temperature alarm configuration: rE= alarm thresholds are relative to set point. Ab=
alarm thresholds are absolute.
-
ALU
High temperature alarm threshold: if this temperature threshold is exceeded for ALd
time, the HA alarm is signalled.
ALC= rE
0...50°C or
90°F
ALC= Ab
ALL...150°C or
302°F
ALL
Low temperature alarm threshold: if the temperature falls below this threshold for
ALd time, the LA alarm is signalled.
ALC= rE
0...50 °C or
90°F
ALC= Ab
- 55°C or -
67°F...AL
U
AHy
Temperature alarm return differential: temperature alarm return differential.
0.1°C...25.5°C
1°F...45°F
ALd
Temperature alarm delay: time interval between the detection of the alarm condition
and its signalling.
0...255 min
Ao
Temperature alarm signalling delay at switch-on.
0 min...23 h
50 min
EdA
Alarm signalling delay after defrosting.
