ELECTRONIC TEMPERATURE CONTROL

 

Description and Functions 

 
The  Electronic  Temperature  Control  is  a  digital  microprocessor  based  temperature  control, 
indication,  and  alarm  system.  It  continuously  monitors  the  temperature  of  the 
refrigerator/freezer  through  its  sensor  assembly.    When  the temperature  warms  to  the  point 
where  it  reaches  the  upper  temperature  limit,  the  controller  sends  a  signal  to  turn  on  the 
compressor,  which  cools  the  unit.  The  snowflake  icon  will  illuminate  on  the  display.  The 
compressor  is  kept  running  until  the  temperature  reaches  the  cold  setting.    When  this  lower 
temperature  set  point  is  reached  the  controller  turns  off  the  compressor  and  the  snowflake 
icon extinguishes.  The refrigerator/freezer warms over time and the process continues.  
 
The Electronic Temperature Control also provides the following functions: 

 

Red LED for visual indication of an alarm condition 

 

Beeper for audible indication of an alarm condition 

 

A preprogrammed 5 minute delay from the time a set point is attained until an alarm 

condition is declared. This prevents spurious alarms for things like door openings.  

 

 

 

Operating Mode 

 
The

 

Electronic  Temperature  Control  normally  displays  the  current  interior  temperature  in 

degrees Celsius. To display the compressor off set point, press the SET button and release. The 
display will momentarily display the set point and then revert to the current temperature. 
 
The control also records the warmest and the coldest temperatures seen by the controller since 
the memory was last reset.  To access these temperatures, press the 

up arrow

 for the warmest 

temperature or press the

 down arrow

 for the coldest temperature.  To clear out the memory, 

press  the  corresponding  arrow  button.  Immediately  press  and  hold  the  SET  button  until  the 
“rSt” message is displayed. The corresponding temperature memory is now erased.
