- Flame failed during run
Initiate new trial for ignition. Flash code
will remain through the ignition trial
until flame is proved.
If system fails to light on next trial for
ignition, check gas supply, pilot burner,
flame sense wiring, contamination of
flame rod, burner ground connection.
4 Flame sensed out of sequence If situation self corrects within 10 sec-
onds, control returns to normal sequence.
If flame out of sequence remains longer
than 10 seconds, control goes to Flash
code 6 + 4 (see below).
Check for pilot flame. Replace gas valve
if pilot flame present. If no pilot flame,
cycle “Call for Heat.” If error repeats,
replace control.
7 Flame sense leakage to ground Control remains in wait mode. When
the fault corrects, control resumes nor-
mal operation after a one minute delay.
Check flame sense lead wire for damage
or shorting. Check that flame rod is in
proper position.
Check flame rod ceramic for cracks,
damage or tracking.
8 Low secondary voltage supply -
below 15.5 Vac)
Control remains in wait mode. When
the fault corrects, control resumes nor-
mal 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 flame sense wiring, flame rod con-
taminated or out of position, burner
ground connection.
6 + 3 More than 5 flame 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, flame
sense wiring, contamination of flame
rod, burner ground connection.
6 + 4 Flame sensed out of sequence -
longer than 10 seconds
Control waits until flame is no longer
sensed and then goes to soft lockout.
Flash code continues. Control auto re-
sets from soft lockout after one hour.
Check for pilot flame. Replace gas valve
if pilot flame present. If no pilot flame,
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 af-
ter one hour.
Reset by cycling “Call for Heat.” If er-
ror repeats, replace the control.
a Flash Code Descriptions:
- Flash Fast: Rapid blinking
- Heartbeat: Constant 1/2 second bright 1/2 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.
