Timed power-up of the display 

This display operates in two operation modes: full-operative mode and power-saving mode. In power-

saving mode the display does not show the time in order to save energy when the display is not needed. If the 
power-saving  function  is  not  needed  and  the  display  should  always  powered  up,  the  both  power-up  and 
power-down times must be the same. 

Parameters of the display 

There  are  three  keys  on  the  back  side  of  the  display.  These  keys  are  used  to  access  and  navigate 

through the menu of the display. The identification of the keys is 

 
   

 

 

 

Advance key. Access parameter/switch digits. 

  
  

 

Enter key. Validate parameter. 

  
  

Increase key. Increase the value of the selected digit. 

  
 

Error displaying 

The only  error that can appear  is a temperature/humidity error. The text  displayed  in  this case is E02  in the 
display. If this occurs, reboot the display.
