Settings and Adjustments

DIP SWITCH (S1) SETTINGS
When replacing an existing ignition control with the S8610U, refer to 69-1955 for the correct DIP switch settings.

Do not power the ignition control prior to setting the DIP switches.

The following timing parameters may be set with this 2-position DIP switch.

PrePurge
To select Prepurge, set SW1 according to Table 2.

Trial for igniTion (Tfi)
To select the Trial for Ignition timing, set SW2 according to Table 2.

Table 2. diP Switch (S1) Settings.

Prepurge	Trial For Ignition	SW1	SW2
None	90 seconds	OFF	OFF
30 seconds	90 seconds	ON	OFF
None	15 seconds	OFF	ON
30 seconds	15 seconds	ON	ON

NOTE: The default factory settings (all OFF) are in Bold in Table 2.

LED Status and Troubleshooting

The ignition control module has two LEDs; one for flame sensing and one for system status:

LED STATUS AND TROUBLESHOOTING
Fig. 4. location of leds.

FLAME LED (YELLOW)
Indicates flame presence and strength. See Table 3.

STATUS LED (GREEN)
Indicates system operation status and error conditions. See Table 4 and the "Troubleshooting Guide" in 69-1955.

Table 3. Yellow led flame codes.

Yellow LED Flash Code a	Indicates	Recommended Service Action
Heartbeat	Normal Flame Signal	Not applicable
2	Weak Flame Signal— System will operate reliably but flame signal is less than desired. NOTE: This indication may flash temporarily during or shortly after lightoff on some applications.	Perform routine maintenance to assure optimum flame signal.
1	Marginal Flame Signal—System may not operate reliably over time. Service call recommended. NOTE: This indication may flash temporarily during or shortly after lightoff on some applications.	Check gas supply, pilot burner, flame sense wiring, contamination of flame rod, burner ground connection.
OFF	Flame Signal below minimum threshold for system operation.	Check gas supply, pilot burner, flame sense wiring, contamination of flame rod, burner ground connection.

Flash Code Descriptions:

Heartbeat: Constant 1/2 second bright, 1/2 second dim cycles.
The flash code number signifies that the LED flashes X times at 2 Hz, remains off for two seconds, and then repeats the sequence.

Table 4. green led Status codes.

Green LED Flash Code (X + Y)	Indicates	Next System Action	Recommended Service Action
OFF	No "Call for Heat"	Not applicable	None
Flash Fast	Startup – Flame sense calibration	Not applicable	None
Heartbeat	Normal operation	Not applicable	None
2	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 contaminated 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, contamination of flame rod, burner ground connection.
4	Flame sensed out of sequence.	If situation self corrects within 10 seconds, control module returns to normal sequence. If flame out of sequence remains longer than 10 seconds, control module 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.
5	Damper Error: Damper required but not present Damper failed to open within 60 seconds Damper failed to close within 60 seconds	If damper error corrects, ignition control resumes normal operation.	Check damper connection, damper wiring, and 24V connection on control. Replace damper if necessary.
7	Flame sense leakage to ground.	Control module remains in wait mode. When the fault corrects, control module 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.	Control module remains in wait mode. When the fault corrects, control module 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	5 minute Retry Delay On every third retry on the 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 contaminated or out of position, burner ground connection.
6+3	On every 6th flame failure during run on the same "Call for Heat."	Initiate new trial for ignition after retry delay completed.	Check gas supply, pilot burner, flame sense wiring, contamination of flame rod, burner ground connection.
6+4	Flame sensed out of sequence for longer than 10 seconds.	Control module waits until flame is no longer sensed and then goes to soft lockout. Flash code continues. Control module 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 the S8610U control module.
ON	Soft lockout due to error detected during self check sequences.	Control module auto resets from soft lockout after one hour.	Reset by cycling "Call for Heat." If error repeats, replace the S8610U control module.

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 2 Hz, remains off for two seconds, and then repeats the sequence.
X + Y flash codes signify that the LED flashes X times at 2 Hz, remains off for two seconds, flashes Y times at 2Hz, remains off for three seconds, and then repeats the sequence.
