GB
Tab. K
33 False flame in stand-by mode
Unexpected flame (false or parasitic flame)
detected during the Stand-by status
Check flame sensor or interference
34 Not used
35 Internal processor timeout Internal fault Replace the control device
36 Internal processor timeout Internal fault Replace the control device
37 Combustion air check timeout
The system could not perform verification
tests of the combustion air during the burner
sequence
Check the wiring or the air pressure switch
38 Internal processor timeout Internal fault Replace the control device
39 Internal processor timeout Internal fault Replace the control device
40 Internal hardware fault Internal fault Replace the control device
41 Internal hardware fault Internal fault Replace the control device
42 Main processor fault Internal fault Replace the control device
43 Supervisor processor fault Internal fault Replace the control device
44 Supervisor processor time-out Internal fault Replace the control device
45 Off-specification mains voltage Off-specification mains voltage/frequency
Check the mains voltage level or the
frequency. Contact the factory if the problem
persists
46 Off-specification mains voltage Off-specification mains voltage/frequency
Check the mains voltage level or the
frequency.
Contact the factory if the problem persists
47 UV: Internal fault Internal fault Replace the control device
48 Supervisor processor fault Internal fault Replace the control device
49 Main processor fault Internal fault Replace the control device
50 Ignition feedback fault
The system detected the presence of voltage
on T16 at the wrong moment or there is no
voltage when necessary
Check the wiring and make sure that the
earthing is appropriate
If the problem persists, contact the distributor/
factory
51 Pilot feedback fault
The system detected the presence of voltage
on T17 at the wrong moment or there is no
voltage when necessary
Check the wiring and make sure that the
earthing is appropriate. If the problem
persists, contact the distributor/factory
52 Piloted valve feedback fault
The system detected the presence of voltage
on T19 at the wrong moment or there is no
voltage when necessary
Check the wiring and make sure that the
earthing is appropriate
If the problem persists, contact the distributor/
factory
53
Actuator feedback waiting time
expired
No actuator feedback on T8 for more than 10
minutes
Check the wiring
Check the modulation equipment
54
Direct ignition valve feedback
fault
The system detected the presence of voltage
on T18 at the wrong moment or there is no
voltage when necessary
Check the wiring and make sure that the
earthing is appropriate. If the problem
persists, contact the distributor/factory
55 Internal processor fault Internal fault Replace the control device
56 UV: false flame during operation False flame detected before ignition Check the flame sensor
57 FR: false flame during operation False flame detected before ignition
Check the wiring
Check the flame sensor
Make sure that earthing is appropriate
58 T8 inlet fault
The system detected the presence of voltage
on T8 at the wrong moment or there is no
voltage when necessary
Check the wiring
Check the actuator
59 Internal hardware fault Internal fault Replace the control device
60 Local reset fault
Local reset button pressed for more than 10
seconds or reset button locked
If the problem persists, replace the control
device
61 Open POC fault The fuel valve is open at the wrong moment Check the wiring
62 UV: strong UV flame fault The flame sensor is too close to the flame
Increase the distance between the sensor
and the flame OR use an orifice to reduce the
view field
63 Internal hardware fault Internal fault Replace the control device
No Faults Cause Solution
