5 minute Retry Delay-
Pilot flame not detected
during trial for ignition
Initiate new trial for ignition after retry
delay completed.
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.
3
Recycle- 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, flame rod
contamination, burner ground connection.
4
Flame sensed out of
sequence
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)
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
normal 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
normal operation after 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
5 minute Retry Delay-
On every third retry on
same “Call for Heat”
Initiate new trial for ignition after retry
delay completed.
Check gas supply, pilot burner, spark
and flame sense wiring, flame rod
contamination or out of position, burner
ground connection.
6 + 3
On every 6th flame
failure during run on the
same “Call for Heat”
5 minute retry delay, then initiate new
trial for ignition.
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
resets 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
after one hour.
Reset by cycling “Call for Heat.” If error
repeats, replace the control
a
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 2
Hz, remains off for three seconds, and then repeats the sequence.
