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.

Indicates
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 re-
mains longer than 10 seconds, control
goes to Flash code 6+4 (see below)
Control remains in wait mode. When
the fault corrects, control resumes nor-
mal operation after a one minute delay.
Control remains in wait mode. When
the fault corrects, control resumes nor-
mal 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 wir-
ing, flame rod contamination or out
of position, burner ground connec-
tion.
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
