CONTROL PROGRAM IN EVENT OF FAULT

INDICATION OF OPERATION

SELF-DIAGNOSTIC Operating concept · Burner control has initiated lockout Þ Red fault LED on · Reset Press lockout reset button for about 1 s · Diagnosis of cause of fault – Press lockout reset button for > 3 s – Press again lockout reset button for > 3 s – Read blink code of red fault LED Þ «Error code table A»

Error code table A Blink code Possible cause 2 x ·· · No establishment of flame at the end of «TSA» – Faulty or soiled detector electrode – Faulty or soiled fuel valves – Poor adjustment of burner – Faulty ignition equipment 3 x ··· · Faulty air pressure monitor – «LP» faulty – «LP» incorrectly adjusted – Fan motor does not run 4 x ···· · Eextraneous light on burner startup 7 x ······· · Loss of flame during operation – Short-circuit between detector electrode and ground 10 x ·········· · Wiring error or internal fault, output contact, unidentifiable fault, e.g. faults that occurred simultaneously
