QUICK FREEZE SP

Use UP/DOWN keys to set desired value. 
This Parameter will set QUICK Freeze Set 
Point during QUICK Freezing  Defrost will 
not occur.

Example 

: If this set to -20 C, and quick 

freeze frequency is set to 1 hr ,then when 

 

it  is  set  to  quick  freeze  mode,  then  the

0

  

Comp. will take -20 C set point for 1 hr.

Use UP/DOWN keys to set desired value. 
This  is  the  maximum  amount  of  time 
allowed  for  Quick  Freeze.  If  set  to  “0”, 
there will be no quick freeze.

Fact. Set 

In time it may be possible that the display 
may  be  offset  by  a  degree  or  so.  To 
compensate for this error, you may need 
to add or minus the degrees required to 
achieve the correct temperature. Setting 

o

o

value is from -10 C to + 10 C.

Example :

 The temperature on the 

o

display is 28 C, whereas the actual 

o

temperature is 30 C. You will need to set 
the Calib. Val to 2, which means that 
once out of the programming mode, the 

o

temperature will show 30 C 

o

o

(28 C + 2 C).

Use UP/DOWN keys to set desired value.
This  parameter  is  used  to  protect  the 
compressor  from  restarting  in  a  short 
period of time and can be set between 0 to 
20 minutes.

Example  :

  If  this  parameter  is  set  at  3 

minutes,  the  relay  will  cut  off  at  the  set 
temperature,  but  will  not  restart  for  a 
minimum  of  3  minutes,  even  if  the 
differential  is  achieved  earlier.  This 
parameter is good to protect the life of the 
compressor or even in applications where 
the probe is placed at places where there 
are  sudden  &  short  changes  in 
temperature .
