"Fdt"
Fan stop time on door open
The delay with wich the fan will be stopped after the door has been opened.
Min. 0 s
"0": fan stop immediately when door open.
Max. 999 s
"1-998": delay for fan stop after door open.
Default 0 s
"999": fan keep running all the time during door open.
"FLt"
Fan limit temperature
This function prevents the evaporator fan to operate if the temperature is
Min. 0°C
above the fan limit temperature.
Max. 50°C
If the defrost sensor registers a higher temperature than the one set here,
Default 50
the fan will be stopped to avoid the warm air circulation in the cabinet. This
parameter is active only when evaporator sensor is connected.
"FdF"
Fan limit Delta temperature
This is the evaporator delta temperature for the fan to switch ON after it is
Min. 1 K
switched off due to FLt setting.
Max. 10 K
Default 2
Lig Light settings
"CLC" Cabinet Light Source Control
This parameter can be set to one of these alternatives to control the light
Min. on
in the cabinet:
Max. dor
"on": always ON.
Default on
"oFF": always OFF.
"dor": door sensor only.
"Lod" Light OFF delay
Number of seconds the light will stay ON after the door has been closed.
Min. 0 s
Max. 300 s
Default 0 s
Pud Pull Down settings
Pull down (sometimes known as Super Cool) is a procedure for improving
cooling performance, accelerating the time used to reach the desired
temperature. Pull down settings overrule all other settings.
"Pit" Pull Down Initiate Temperature
This parameter indicates the temperature which causes a pull
Min. -40.0°C
down to start. If the temperature measured inside the cabinet
Max. 50.0°C
exceeds this value for longer than one hour, then pull down will
Default 50.0°C
start. During this period compressor will run at maximum speed
and stop defrost cycles until the desired temperature (PLt) is
reached or pull down duration (Pdd) expires. The period of one
hour is fixed and cannot be altered.
"PCy" Pull Down Cycling
This is the duration in minutes of the compressor cycling at the reduced
Min. 0 min
set point temperature. Once the desired pull down limit temperature
Max. 360 min
"PLt" has been reached during pull down, the compressor will continue to
Default 30 min
cycle ON/OFF for the duration of "PCy". At the end of the period defined by
"PCy", the set point temperature will return to normal and pull down will
cease.
"Pdi" Pull Down Defrost Interval
This is the time between defrost cycles during pull down. It is measured in hours and can be up to 48 hours.
Min. 0 hour
During pull down, this setting overrides the normal defrost interval settings.
Max. 48 hour
Default 15 hour
"Pdd" Pull Down Duration
Maximum time for pull down. If time expires pull down will stop, regardless of temperature.
Min. 0 hour
Max. 48 hour
Default 24 hour
