Fan Delay after Defrost / Fdd
This parameter can be set to between 0 and 60 seconds and defines how
1 Click: Temperature setpoint
long the delay is between the start of the compressor after defrost and the
Sub function: Up
fan starting again .
Fan Start Temperature / Ftd
1 Click: Temperature setpoint
This only applies if an evaporator temperature sensor is fitted . This parameter
Sub function: Down
determines at what evaporator temperature the fan will start after a defrost cycle
is complete .
If the time set in Fdd occurs before the temperature set in Ftd, the fan will start
in line with Fdd . If the temperature set in Ftd occurs first, then the fan will start in
1 Click: Temperature setpoint
line with Ftd . It is therefore a case of whichever parameter's setting is reached first
Sub function: Up
1 Click: Temperature setpoint
which determines when the fan starts .
Sub function: Down
Defrost Fan On / dFA
1 Click: Temperature setpoint
Set to yES, the fan will constantly run during defrost cycles .
Sub function: Up
Set to nO, the fan will not run during defrost cycles .
Initial Defrost Interval / idi
The initial defrost interval determines the time for first defrost after power-up . The
1 Click: Temperature setpoint
initial defrost is mainly intended for factory testing of the defrost functionality and
Sub function: Down
can be set to expire after a number compressor cycles according to the setting
1 Click: Temperature setpoint
of parameter idd . During normal operation, the defrost counter will be saved in
Sub function: Up
memory and restored after power loss, making the initial defrost unnecessary .

Initial Defrost Duration / idd
The initial defrost duration is the number of compressor cycles before the initial
defrost is deactivated .
0: idi No initial defrost
1 Click: Temperature setpoint
1-998: number of compressor cycles before deactivation
Sub function: Up
999: Initial defrost always active .

Sub function: Down
Defrost On Compressor Time / dCt
If this parameter is set to yES, then defrost cycles are based on the total time
the compressor has been running .
If this parameter is set to nO, then defrost cycles are related to elapsed time,
regardless of how long and how often the compressor has been on .
