Description
Compressor stop delay on door
open (Sec.)
Cdd
0
0
999
It sets the delay in stopping the compressor when the door is opened. If set to "0",
the compressor stops immediately. If set to 999 it will disable the function and does-
not stop the compressor
System Resume after door open
(Mins)
Srt
0
0
60
If the door is kept open for a long time, the compressor and fan will resume after
this time if they are switched o due to open door. (Note : 'Srt' must be always great-
er than' Cdd' and 'Fdt') If Srt=0, the system resume feature is disabled and the sys-
tem will resume only when the door is closed.
Power On Delay (Sec.)
Pod
120
0
300
This is the delay in seconds between power-on and the output relays being activa-
ted.

Time delay to raise alarm if the door is kept open. If the door is closed before the
delay time, no alarm will be raised

Time delay to raise high temperature alarm during pull down, power-up and defrost
in order to avoid wrong alarm signal during these conditions.

Hgd
EETc 11, 12
It denes the required type of defrost:
“no” : defrost function is disabled
“nAt” : natural defrost (OFF-cycle defrost)
EETc 21, 22
It denes the required type of defrost:
“no” : defrost function is disabled
“nAt” : natural defrost (OFF-cycle defrost)
“EL” : electrical defrost
“Hgd” : hot gas defrost
Minimum defrost Interval (Mins)
dii
360
1
4320
Denes
the minimum time period between the start of two defrost cycles. If the
evaporator temperature goes below the defrost start temperature (dEt), the control-
ler triggers the defrost after this period. It not, it triggers the defrost at the Maxi-
mum defrost interval (dAi)
Maximum defrost Interval (Mins)
dAi
420
1
4320
Maximum time period between the start of two defrost cycles.
Minimum defrost time (Mins)
dit
5
0
240
Denes
the minimum duration of a defrost cycle. During this period, the controller
will not check the temperature. Once the minimum time has expired, the tempera-
ture will be checked and if the terminate temperature "dtt" has been reached, the
defrost cycle will end. If “dtt” has not been reached, defrost will continue until the
maximum defrost time "dAt" is reached
Maximum defrost Time (Mins)
dAt
30
0
480
Maximum duration of a defrost cycle. The controller will terminate the defrost after
this time, even if the evaporator sensor is congured and the evaporator tempera-
ture is less than terminate temperature (dtt).
Defrost Terminate Temp (°C)
dtt
6
0
50
It
denes the evaporator temperature at which defrost must be terminated. The
controller will terminate the defrost based on the defrost terminate temperature
(dtt) or the Maximum defrost time (dAt). If no evaporator sensor is used, defrost will
be terminated based on the maximum defrost time (dAt)
Defrost On accumulated Compres-
sor Run Time
dCt
No
No
Yes
If it is set to "Yes", the defrost interval is calculated based on the total time the com-
pressor has been running. If it is set to “No”, then defrost interval is based on the
elapsed time, regardless of compressor ON time.
Defrost Start by Evaporator Temp
(°C)
dEt
-100
-100
0
Evaporator Temperature at which the defrost will be triggered after a minimum de-
frost interval to avoid excess frost on the evaporator (only active if the evaporator
sensor is congured)
Drip
O time (Mins)
dot
2
0
60
Denes
the time delay to start the compressor after terminating defrost. This feature
is to ensure no water droplet on the evaporator before starting the cooling cycle
