**) „10“ will flash in display if more than 5 remote resets were attempted via the bus within 15 minutes.  Further remote 
resets are not possible, burner must be reset manually at the burner control box. ( Limitation is implemented to prevent 
continuous resetting in case of a bus failure)  Local reset will re-enable remote reset. 
 

  

 

 
During operation the 7-segment display will show the current program status.  Flame signal strength and other parameters 
will be displayed by repeatedly pressing the Reset/Info button.  
Should a fault occur, the CBF-/CBFF will terminate operation and display a flashing fault code.  Meaning of fault code can be 
determined from fault schedule attached to front of control box (see Fig. 2)  Fault schedule is available in several languages 
and can be exchanged easily.  CBF-/CBFF DP will display „- -„ signalising stand-by mode if the box is turned off.  The bus 
system will remain functional to enable communication to other devices.  Control outputs of CBF-B1/CBFF-B1 (ignition, sole-
noid valves) are electrically separated from the power supply.
