P6
Parameter

Use UP/DOWN keys to set desired value. 
This parameter is used to protect the fan 
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,  once  compressor  will  cut  off  at 
the set temperature, it 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  when  there  are  power 
fluctuations  and  the  compressor  is 
switched off and on within a few seconds.

Example 

:  The  temperature  on  the

display  is  28.0 C,  whereas  the  actual 

O

temperature is 30.0 C. You may need to

Use UP/DOWN keys to set desired value. 
In time it may be possible that the display 
may be offset by a degree or so.
To compensate this error, you may need 
to add or minus the degrees required to 
achieve the correct temperature.

   Fact. Set 

This is maximum amount of time allowed

Example :

 If P7 is set to 15 Mins and P8 

parameter is set to 1 Hr. then after every 1 
Hr defrosting will take place for 15 mins.

Example  : 

If  P9  parameter  is  30  mins
