      SETTING OF COMPRESSOR DELAY TIME 

 
The delay time of low stage side compressor can be set to reduce the load on the power line and to 
facilitate the start-up (reset) of the freezer after power failure. 
 
The example in the table is based on the assumption that the delay time is changed to 4 minutes.    The 
delay time is set to 5 minutes at the factory.

 

 

Note:

 

 The setting range for delay time is between 3 and 15 minutes.    The cool down of chamber temperature 

may be slow when the setting of delay time is over 8 minutes, depending on the installation environment. 

 There is no need of changing the delay time when the capacity of power source is enough. 

 

Table 8    Changing procedure for delay time (change from 5 minutes to 4 minutes)

 

 

Description of operation 

Key operated 

Indication after operation 

1  

---- 

The current chamber temperature is 
displayed. 

Press numerical value shift key for 
5 seconds. 

 

The first digit is flashed. 

Set the figure to F05 with the 
numerical value shift key. 

 

When pressed, the figure of settable   
digit changes. 

4  Press set key. 

SET 

The current delay time is displayed. 
The first digit is flashed. 

Set the figure to 004 with the 
numerical value shift key. 

 

When pressed, the figure of the first 
digit changes. 

6  Press set key. 

SET 

The delay time is memorized and   
the current chamber temperature is   
displayed. 

 The start up may be behind the delay time set by the above procedure because the compressor is 

affected by the chamber temperature and temperature of cascade condenser installed in the freezer.  
(The high stage side compressor starts to operate without delay time at the time of power on or after 
power failure.) 

 The compressor delay time set mode returns to the temperature display mode automatically when 90 

seconds has passed without any key operation.
