Manual Defrost
The appliance will automatically run a defrost cycle every six hours.
To manually defrost the appliance:
1. Press and hold the DEFROST button for 5 seconds.
2. The defrost cycle will start immediately and the Defrost LED illuminates.
The defrost will last a maximum of 30 minutes.
3. The next automatic defrost will start six hours after the manual defrost
has finished.
Note:
If a button is not pressed for 10 seconds while using the
control panel it times out and reverts to standby mode.
When parameters are being set the Setpoint LED will flash on
the display.
Parameter Name Description Range
d1 Operating temperature Set the operating temperature of the appliance -2°C to 10°C

Temperature
Differential
The Temperature Differential is the allowed temperature difference above and below the
operating temperature before the compressor starts/cuts off
0 to 20°C
d3
Temperature Range
Set the minimum (d3) and maximum (d4) temperatures that the appliance can fluctuate
between
-40°C
d4 95°C
d5
Compressor Activation
Time Intervals
Enter the minimum time interval between the compressor turning off after turning on. 0-999 seconds
d6
Maximum Temperature
Differential Alarm
Set an alarm to sound if the temperature inside the appliance exceeds the set operating
temperature by a specified amount
0°C-50°C
d7
Temperature
Differential Alarm Delay
Set a delay before the temperature differential alarm is triggered 0-99 minutes
d8
Defrost Cycle Time
Intervals
Set the time between each defrost cycle 1-999 hours
d9
Maximum Defrost
Duration
Set the maximum length of the defrost cycle
Note: The defrost duration can be overridden by parameter d10 (below), if the
cut-off temperature is reached before the end of the defrost duration
0-999 minutes
d10
Defrost Cut-off
Temperature
Set the defrost cut-off temperature -45°C to 50°C
d11
Additional Cut-off
Defrost Period
Set an additional amount of defrost time after the defrost cut-off point has been reached (if
required)
0-99 minutes
d12
Delayed Actual
Temperature Display
Set the length of time the inner temperature of the appliance (before defrost started) is
displayed for after a defrost cycle has finished
0-99 minutes
d13
Compressor On/Off
During Defrost
Turn the Compressor On or Off during the defrost cycle On (1) or Off (0)
d14 Evaporator Drying Time
Set the amount of time the compressor remains turned Off after a defrost cycle, reducing the
amount of frost build up
0-99 minutes
=19 Temperature Offset
Should there be any variance between measured and actual temperature, the measured
temperature can be offset to compensate
-20°C to 20°C
=22 Unit of Measurement Set whether the temperature is displayed in Centigrade or Fahrenheit Centigrade (0) or Fahrenheit (1)
=23
Compressor Operation
During Probe Failure
Set whether the compressor runs or remains Off during a temperature probe failure
Compressor runs (1)
Remains Off until fault fixed (0
)
Runs intermittently with
parameters =24 and =25 (2)
=24
Compressor ‘On’
Duration
Set the length of time the compressor runs during a temperature probe failure 1-99 minutes
=25
Compressor ‘Off’
Duration
Set the length of time the compressor remains Off during a temperature probe failure 1-99 minutes
=34
Initial Defrost After
Startup
Set whether the appliance starts a defrost cycle 10 minutes after startup or after the time
programmed in parameter d8 (Defrost Cycle Time Intervals)
Begins 10 minutes after startup
(0) or when programmed (1)
=38
Minimum Temperature
Alarm
Set the display to flash should the inner temperature of the appliance drop beyond a specified
point from the programmed operating temperature
1°C to 50°C
Note: The cycle starts from the time the appliance is initially
powered up.
Note: Starting a manual defrost also resets the automatic
defrost timer.
