- Flame failed during run.
Initiate new trial for ignition. Flash
code will remain through the ignition
trial until ame is proved.
If system fails to light on next trial for ignition,
check gas supply, pilot burner, ame sense
wiring, contamination of ame rod, burner
ground connection.
Flame sensed out of
sequence
If situation self corrects within 10
seconds, control returns to normal
sequence. If ame out of sequence
remains longer than 10 seconds,
control goes to Flash code 6 + 4
(see below).
Check for pilot ame. Replace gas valve if pilot
ame present. If no pilot ame, cycle “Call for
Heat.” If error repeats, replace control.
Flame sense leakage to
ground
Control remains in wait mode. When
the fault corrects, control resumes
normal operation after a one minute
delay.
Check ame sense lead wire for damage or
shorting. Check that ame rod is in proper
position. Check ame rod ceramic for cracks,
damage or tracking.
Low secondary voltage
supply - (below 15.5 Vac)
Control remains in wait mode.
When the fault corrects, control
resumes normal operation after a
one minute delay.
Check transformer and AC line for proper input
voltage to the control. Check with full system
load on the transformer.
6+2 Failed trial for ignition
resulting in lockout
Remain in lockout until “Call for
Heat” is cycled.
Check gas supply, pilot burner, spark and ame
sense wiring, ame rod contaminated or out of
position, burner ground connection.
6+3 More than 5 ame failures
during run on the same
“Call for Heat” resulting in
lockout
Remain in lockout until “Call for
Heat” is cycled.
Check gas supply, pilot burner, ame sense
wiring, contamination of ame rod, burner
ground connection.
6+4 Flame sensed out of
sequence - longer than 10
seconds.
Control waits until ame is no
longer sensed and then goes to
soft lockout. Flash code continues.
Control auto resets from soft lockout
after one hour.
Check for pilot ame. Replace gas valve if pilot
ame present. If no pilot ame, cycle “Call for
Heat.” If error repeats, replace control.
ON Soft lockout due to error
detected during self check
sequences
Control auto resets from soft lockout
after one hour.
Reset by cycling “Call for Heat.” If error repeats,
replace the control.

Flash Code Descriptions:
– Flash Fast: rapid blinking.
– Heartbeat: Constant ½ second bright ½ second dim cycles.
– A single flash code number signifies that the LED flashes X times at 2Hz, remains off for two seconds, and then repeats
the sequence.
– X + Y flash codes signify that the LED flashes X times at 2Hz, remains off for two seconds, flashes Y times at 2Hz, remains
off for three seconds, and then repeats the sequence.
