Example :

Use UP/DOWN key to set 
desired value. 

If L1 parameter(Evap. fan 
stop temp.) is set to 2°C, and 
the L4 is set to 2°C, then 
evap. fan will cut off at 2°C 
and restart only at 0°C. 

To change the 
L4 parameter, 
press the SET key.

Function 

: Evap. fan 

differential (hysteresis).

PROGRAMMING MODE 
COIL PROBE DIFF.

L4 Parameter

Example : 

The temperature 

on the LCD is 28°C, whereas 
the actual temperature is 
30°C. You will need to set this 
parameter to 2°C, which 
means that once out of 
programming mode, the 
temperature will show 30°C

Use UP/DOWN key to set 
desired value. 

In time it may be possible that 
the temp. on LCD 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.

(28°C + 2°C).

Use UP/DOWN key to set 
desired value. 

1 = Evap. Fan will stay OFF   

 

      during defrost.

0 = Evap. fan will stay ON  
      during defrost.

L6 parameter,

Use UP/DOWN key to set 
desired value. 

This parameter controls the 
evap. fan on/off status 
depending on the digital input 
(Door input).

0 = Evap. Fan will stay ON 

      OFF with door fault.   

1 = Evap. fan will turn stay  

      door fault.

Function :

   To set Condenser 

delay to start before comp.

Example : 

If this parameter 

set to 10 sec and P6 = 3 min. 
then condenser will turn ON 
10 seconds before 
compressor. 

Use UP/DOWN key to set 
desired value. 

To change the

defrost.

Use UP/DOWN key to set 
desired value. 

       during Hot gas defrost.

1 = Condenser will be ON  

0 =  Condenser will be OFF   

      during Hot gas defrost.

To change the 
d2 time parameter, 
press the SET key.

PROGRAMMING MODE

Function 

: To  set  quick  freeze 

set point.

Use UP/DOWN key to set 
desired value. 

Example : 

If this is set to -

5°C,  and quick freeze time 
duration is set to 1 hr, then 
when it is set to quick freeze 
mode,  the compressor will 
take -5°C set point for 1 hr.

Function : 

To set Quick Freeze 

time duration.

See CS parameter. 

Example :

This is maximum amount of 
time allowed for Quick 
Freeze. If set to 0, there will 
be no quick freeze.

Use UP/DOWN key to set 
desired value.

Function : 

To set / activate 

power up defrost cycle.

This parameter will decide to 
start power up defrost or not.

Use UP/DOWN key to set 
desired value. 

0= No power up defrost.
1= Power up defrost after 1 Hr.

Example : 

This parameter will 

help to achieve first defrost 

2= Power up defrost after 2 Hr.
3= Power up defrost after 3 Hr.

press the SET key.

To change the
