No Faults Cause Solution
1 Post-diagnostics fault Initial power diagnostics fault
Make sure that the status of inlets and
outlets is correct upon ignition
Check T12, T13 and T14
2 Local reset The user started the manual reset or the
reset switch is faulty
Check T21 inlet or reset for normal
operation
3 Combustion air fan fault No Air Check signal (T14) during the bleed
cycle or Air Check signal loss during the
burner operation
Check the fan or the air pressure switch
4 Supervisor processor
diagnostics fault
The system detected the presence of
voltage on T16, T17, T18 or T19 at the
wrong moment or there is no voltage when
necessary
Check the wiring and make sure that the
system is operating on a single-phase line
(50/60Hz)
5 FR- No flame at the end of the
2
nd
safety time (MTFI)
No flame at the end of the second safety
time
Inspect the system, check the gas pressure,
inspect the flame detection electrode, check
the wiring, etc.
6 FR: internal circuit fault Internal fault Replace the control device
7 Internal communication fault Internal fault Replace the control device
8 Remote reset The user pressed the remote reset button or
the reset switch is discontinuous/dynamic
Check the remote switch
9 FR: internal fault Internal fault Replace the control device
10 Main processor fault Internal fault Replace the control device
11 Data memory test fault Internal fault Replace the control device
12 Data memory test fault Internal fault Replace the control device
13 Mains voltage or frequent fault Off-specification power supply voltage and/
or frequency
Check the input power supply
14 Internal processor fault Internal fault Replace the control device
15 Internal processor fault Internal fault Replace the control device
16
No flame: 1
st
safety time (PTFI)
No flame at the end of the first safety time Inspect the system, check the gas pressure,
check the UV scanner, check the wiring,
etc.
17 Wiring fault The system detected the presence of
voltage on critical terminals (T16, T17, T18
or T19) at the wrong moment or there is no
voltage when necessary
Inspect the wiring and make sure that the
system is operating on a single-phase line
(50/60Hz)
18 Safety relay fault Internal fault Replace the control device
19 Combustion airflow switch fault
in the rest position
Open the circuit upon T13 start-up Check the wiring for the air pressure switch
