DDY
Display delay The display shows the information selected with parameter ‘DDM’ during defrost and for
‘DDY’ minutes after defrost termination
FID
Evaporator Fans in defrost YES - Fans active during defrost and drain (‘DRN’) and recovery / NO - Fans o during
defrost and drain (‘DRN’) and recovery (fan start based on ‘FDD’ or ‘FTO’ - whichever rst)
FDD
Evaporator fan re-start
temperature after defrost
FTO
Maximum evaporator fan stop
after defrost
FSD
‘Evaporator fan stop delay after
door opens
Time in seconds: ‘-1’ = fan(s) do not stop / ‘0’ = fan(s) stop instantaneously / ‘1’-’900’ = fans
stop after prescribed time elapses
FCM
Thermostatic control fan mode ‘NON’ - The fans remain ON all the time (subject to door switch operation and defrosts).
‘TMP’ - Temperature-based control. The fans are ON when the compressor is ON. When
the compressor is turned OFF, the fans remain ON as long as the temperature dierence
Te-Ta is greater than ‘FDT’
TIM’ - Timed-based control. The fans are ON when the compressor is ON. When the
compressor is OFF, the fans switch ON and OFF according to parameters ‘FT1’, ‘FT2’ and
‘FT3’
FDT
Evaporator fan compressor
stop over-run
Where Evaporator (Te) -Air (Ta) temperature dierence for the fans to turn OFF after the
compressor has stopped
FDH
Temperature dierential for fan
re-start
Example: ‘FDT’ = ‘-1’ and ‘FDH=3’. If compressor is stopped, the fans are OFF when Te> Ta
‘-1’ (‘FDT’), whereas the fans are ON when Te < Ta ‘-4’ (‘FDT’-’FDH’)
FT1
Fan stop delay after compressor
stop
FT2 Timed fan stop When ‘FT2’ = ‘0’ the fans remain on all the time
FT3 Timed fan run When ‘FT3’ = ‘0’, and ‘FT2’ > ‘0’, the fans remain OFF all the time
ATM
Alarm threshold management ‘NON’ - all temperature alarms are inhibited (the following parameter will be ‘ACC’)
‘ABS’ - the values programmed in ‘ALA’ and ‘AHA’ represent the real alarm thresholds
‘REL’ - the alarm threshold is obtained by the sum of setpoint, thermostat dierential and
‘ALR’ / ‘AHR’
ALA
Low temperature alarm
threshold
AHA
High temperature alarm
threshold
ALR
Low temperature alarm
dierential
With ‘ALR’ = ‘0’ the low temperature alarm is excluded
AHR
High temperature alarm
dierential
With ‘AHR’ = ‘0’ the high temperature alarm is excluded
ATI
Probe used for temperature
alarm detection
PAD
Delay before alarm
temperature warning at power
on
ATD
Delay before alarm
temperature warning
ACC
Condenser periodic cleaning When the compressor operation time, expressed in weeks, matches the ‘ACC’ value
programmed, ‘CL’ ashes in the display. With ‘ACC’ = ‘0’ the condenser cleaning warning is
disabled

DSM
Door switch mode ‘NON’ - when ‘DI1’/’T3A’ = ‘DOR’ there is no response to a state change
‘ALR’ - when ‘DI1’/’T3A’ = ‘DOR’ and the digital input is ON, an alarm is generated after
‘DAD’ minutes
‘STP’ - when ‘DI1’/’T3A’ = ‘DOR’’ and the digital input is ON, in addition to the alarm, the
fans are stopped according to FSD and the compressor is stopped after ‘CSD’ seconds
