Initial Pull Down:
OFF - Disable
ON - Enable
Initial Pull Down (IPD) can be used for providing faster cooling when the cabinet is
powered up with warmer inside temperature. During IPD, defrost will be skipped
until the cabinet air temperature reaches cut-out temperature or the IPD duration
expires. IPD operates only during power-up and can be enabled/disabled using it.
Initial pull down and pull down du-
ration (Hrs)
IPD

Maximum time IPD and Pull Down can run. IPD and Pull Down will terminate as
soon as this time expires, regardless of the cabinet air temperature.

120
It indicates the temperature at which IPD or Pull Down will be initiated:
• At Power up: If the cabinet air temp. > Pit for more than 5 minutes it will trigger
the Initial Pull Down
• During Normal operation: if the cabinet air temp stays above Pit>1hr it will trig-
ger the Pull Down

This parameter sets the cut out temperature oset during Pull-down cycle to ach-
ieve more cooling. When set as “0” pull down feature is disabled.

Description
Compressor
COP
Min Run time (Sec.)
Crt
0
0
1800
To prevent the compressor from frequent cut-outs, it ensures that the compressor
runs for at least the specied time. It overrides the cut-out temperature. (Tip: setting
it too high could lead to unneccessary deep temperatures)
Min Stop time (Sec.)
CSt
120
0
1800
To prevent the compressor from frequent cut-ins, it ensures that the compressor re-
mains o for at least the specied time under this parameter. It overrides the cut-in
temperatures. (Tip: setting it too high could lead to unneccessary warm tempera-
tures)
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”, the function will be disabled and
the compressor will not be stopped
System Resume after door open
(Mins)
Srt
0
0
60
If the door is kept open for a long time, the compressor and the fan will resume after
this time, if they switched o due to an 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.
Second Compressor start delay

0
960
Delay time for starting the second compressor in dual compressor control
