supply- (below 15.5 Vac)
5 minute Retry Delay-
6 + 2 On every third retry on
same "Call for Heat"
On every 6th flame
6 + 3 failure during run on the
same "Call for Heat"
Flame sensed out of
6 + 4 sequence- longer than

Soft lockout due to error
ON detected during self
check sequences
Flash Code Descriptions:
a
- 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
2 Hz, remains off for three seconds, and then repeats the sequence.

Initiate new trial for ignition after
retry delay completed.
Initiate new trial for ignition. Flash
code will remain through the ignition
trial until flame is proved.
If situation self corrects within 10
seconds, control returns to normal
sequence. If flame out of sequence
remains longer than 10 seconds,
control goes to Flash code 6+4 (see
below)
Control remains in wait mode.
When the fault corrects, control
resumes normal operation after a
one minute delay.
Control remains in wait mode.
When the fault corrects, control
resumes normal operation after one
minute delay.
Initiate new trial for ignition after
retry delay completed.
5 minute retry delay, then initiate
new trial for ignition.
Control waits until flame is no
longer sensed and then goes to
soft lockout. Flash code continues.
Control auto resets from soft
lockout after one hour.
Control auto resets from soft
lockout after one hour.

If system fails to light on next trial for
ignition check gas supply, pilot burner,
spark and flame sense wiring, flame rod
contamination or out of position, burner
ground connection.
If system fails to light on next trial
for ignition check gas supply, pilot
burner, flame sense wiring, flame rod
contamination, burner ground connection.
Check for pilot flame. Replace gas valve
if pilot flame present. If no pilot flame,
cycle "Call for Heat." If error repeats,
replace control.
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.
Check transformer and AC line for proper
input voltage to the control. Check with
full system load on the transformer.
Check gas supply, pilot burner, spark
and flame sense wiring, flame rod
contamination or out of position, burner
ground connection.
Check gas supply, pilot burner, flame
sense wiring, contamination of flame rod,
burner ground connection.
Check for pilot flame. Replace gas valve
if pilot flame present. If no pilot flame,
cycle "Call for Heat." If error repeats,
replace control.
Reset by cycling "Call for Heat." If error
repeats, replace the control
