OTHER FEATURES OF THE UNIVERSAL-R 

As well as the main digital display, there are some small icons on 
the front panel. These are used to monitor the loads controlled by 
the instrument. Each icon function is described in the following 
table.

THERMOSTAT OVERRIDE ( not available when parameter tC = 1 or 7 ) 

For rapid chilling or freezing, the thermostat can be overridden by pressing the UP button until the 

 icon lights up. The compressor will 

run  in  continuous  mode,  irrespective  of  temperature,  for  the  time  period  set  in  parameter  CCt.  Normal  operation  will  then  resume 
automatically. The cycle can also be terminated manually by pressing the UP button again for about 3 seconds.

Action 

1 or 7 

No defrost 

Off cycle defrost by timer 

3, 4, 5 or 6 

Forced type of defrost: Electrical or Hot Gas 

 

-

 

tdF = 0: defrost is electrical;  

-

 

tdF = 1: defrost is by hot gas. 

13.

 

EVAPORATOR FAN CONTROL (only when parameter tC = 5 or 6) 

The fan control mode is selected by means of the “FnC parameter: 
 

FnC parameter 

Action 

Fans will cycle ON and OFF with the compressor and be off during defrost cycle. 

Fans will run continuously, but be off during defrost cycle. 

Will switch ON and OFF with the compressor and be on during defrost cycle (*). 

Fans will run continuously and be on during defrost cycle (*). 

 
(*) Note: Fans will stop if the temperature value set in parameter “FSt is exceeded.
