Description
Fan Delay After Defrost (Sec.) (appli-
cable only for EETc 2x series)
Fdd
0
0
960
Denes delay in switching “ON” the fan from compressor start after defrost to avoid
warm air circulation
Fan Start Temperature after defrost
(°C) (applicable only for EETc 2x ser-
ies)
Ftd
25
-25
25
It determines at what evaporator temperature the fan will start after a defrost cycle.
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 rst, then the fan will start in
line with “Ftd”
Fan ON during Defrost (applicable
only for EETc 2x series)
dFa
no
no
Yes
Denes the status of the fan during defrost. Set to "Yes", the fan will run during de-
frost cycles and set to "No", the fan will be kept o during defrost cycles
Initial Defrost Interval (Mins)
idi
180
0
4320
The initial defrost interval determines the time for rst defrost after power-up. The
initial defrost is mainly intended for factory testing of the defrost functionality and
can be set to expire after a number compressor cycles according to the setting of
parameter idd.
Initial defrost duration (Cycles)
idd
0
0
999
The initial defrost duration is the number of compressor cycles after which initial de-
frost is deactivated.
“0” : No initial defrost
“1-998” : number of compressor cycles before deactivation
“999” : initial defrost always active.

Fan Control Method
FCt
FAo
FAo
FPL
Denes the fan control method:
“FAo” : fan always on
“FFc” : fan follows compressor (fan runs only when compressor is ON)
“FPL” : fan cycling (fan cycling during compressor o cycle)
Fan ON Delay (Sec.)

Fan Stop Delay (Sec.)

Time delay to stop the fan after compressor cut-out
Fan On Cycle (Sec.)
FoC

0
960
If fan control method is selected as "FPL", it denes the fan ON time during compres-
sor OFF cycle.
Fan Stop Cycle (Sec.)
FSc
0
0
960
If fan control method is selected as "FPL", it denes the fan OFF time during com-
pressor OFF cycle.
Fan stop delay on door open (Sec.)
Fdt
0
0
999
The delay to stop the fan after the door has been opened:
“0” : fan stop immediately when door opens
“1-998” : delay for fan stop after door opens
“999” : fan keep running all the time, fan does not stop while door is opened
Fan Minimum Stop Time (Sec.)
FSt
10
0
960
Minimum time that the fan must stop whenever it is switched o.
Fan Limit Temperature (°C)
FLt
50
0
50
This function prevents the evaporator fan from operating if the evaporator tempera-
ture is above the fan limit temperature. If the defrost sensor registers a higher tem-
perature than the one set here, the fan will be stopped to avoid the warm air circula-
tion in the cabinet. The fan will restart when the evaporator temperature goes 2 °C
less than FLt (FLt - 2 °C). It is active only when the evaporator sensor is congured.
