SELF-DIAGNOSTIC
Operating concept
Burner control has initiated lockout
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
«Error code table A»
