Cause
Initial power diagnostics fault
Make sure that the status of inlets and
outlets is correct upon ignition
The user started the manual reset or the
reset switch is faulty
No Air Check signal (T14) during the bleed
cycle or Air Check signal loss during the
burner operation
The system detected the presence of
voltage on T16, T17, T18 or T19 at the
wrong moment or there is no voltage when
necessary
No flame at the end of the second safety
time
Internal fault

The user pressed the remote reset button or
the reset switch is discontinuous/dynamic

No flame at the end of the first safety time
The system detected the presence of

Solution
Check T12, T13 and T14
Check T21 inlet or reset for normal
operation
Check the fan or the air pressure switch
Check the wiring and make sure that the
system is operating on a single-phase line
(50/60Hz)
Inspect the system, check the gas pressure,
inspect the flame detection electrode, check
the wiring, etc.
Replace the control device
Replace the control device
Check the remote switch

Inspect the system, check the gas pressure,
check the UV scanner, check the wiring,
etc.
Inspect the wiring and make sure that the
system is operating on a single-phase line
(50/60Hz)
Replace the control device
Check the wiring for the air pressure switch
