The upper display will continuously show the  
The detected ‘System’ pressure and the lower 
display will show the percentage load of the 
DX Box ‘group’. 
 
Press UP and DOWN to view the status, 
‘Delivery’ pressure (if enabled) and 
‘Differential’ pressure (if applicable) for each 
compressor in the ‘group’. 
 

 

 

When viewing the status or pressure 
information for a compressor the ‘network 
address’ and DX Box identification will be 
show on the upper display (for example, 
“C.03.1” indicates that the compressor is 
connected to the DX Box as compressor #1 
and the DX Box is represented on the system 
management unit as compressor number 
“03”). The status of the compressor will also 
be show using the ‘Run’ and ‘Load’ symbols. 
 

 

 
If the ‘Delivery’ pressure sensor option for a 
compressor has not been enabled the lower 
display line will not be shown and the 
‘differential’ pressure item will not be available.
