22 Error code list with operation via internal LED

Possible cause
Program sequence of program module does not
match to the basic unit
- Error in data content of program module
- No program module fitted
- Faulty or soiled fuel valves
- Faulty or soiled flame detector
- Poor adjustment of burner, no fuel
- Faulty ignition equipment
Air pressure switch (LP) faulty
- Loss of air pressure signal after specified time
(t10)
- Air pressure switch (LP) is welded in no-load
position
Extraneous light when burner startup
Time out air pressure switch (LP)
- Air pressure switch (LP) is welded in working
position
- Actuator faulty or blocked
- Faulty connection
- Wrong adjustment
Too many losses of flame during operation
(limitation of repetitions)
- Faulty or soiled fuel valves
- Faulty or soiled flame detector
- Poor adjustment of burner
