SETUP AND ADJUSTMENTS
DIP Switch (S1) Settings
When replacing an existing ignition control with the C107U, refer to Table
2 for the correct DIP switch settings. For a complete list of the controls the
C107U replaces, see the BASO C107U Installation Instructions available
at www.baso.com.
The following timing parameters may be set with the 5-postion DIP switch
(see Table 2).
IMPORTANT:
The control timing configuration is permanently locked and cannot be reset
by changing the DIP switch settings after 10 consecutive power cycles.
FACTORY DEFAULT S1 DIP SWITCH SETTING
TIMING CONFIGURATION LABEL
Note: After the configured number
of trials for ignition with no established flame or the pre-defined number of
flame losses have occurred, controls with a retry time of 0 (i.e. none) will
enter a 100% Lockout mode, requiring the pre-defined lockout recovery
method (power cycle) to continue normal operation. However, controls
with a retry time of 5 or 60 minutes will enter a standby lockout mode for
the configured time before continuing to normal operation.
All switch settings are defaulted from the
factory to the “ON’ position. Refer to Table 2
for the desired timing configuration. The
default timings are printed on the label
located on the front of the ignition.
Once you have selected the desired timing
configuration, using a permanent marker,
write in the values and mark the DIP switch
settings on the label provided. Adhere the
label to the front of the control for future
reference.

LED STATUS AND TROUBLESHOOTING
The ignition control has a multi-colored (GREEN, ORANGE, and RED)
LED which will flash different colors and codes to show status of the
ignition and will help troubleshoot the control.
Table 3: GREEN LED Indications of Normal Operation
Flash Indication
1 flash every 1 sec. Pre-purge, Inter-purge
Rapid flashing Trial for Ignition (TFI)
Solid on RUN (Flame, Main valve on)
Table 4: ORANGE LED Indications
Flash Indication Error Type
1 flash every 5 sec. Retry Standby
1 flash every 1 sec. Flame Present Standby
Table 5: RED LED Indications of ERROR Codes (100% Lockout)
Flash Indication Error Type
1 flash No flame in trial time 100% Lockout
2 flashes Flame sense stuck 100% Lockout
3 flashes Valve relay circuit 100% Lockout
7 flashes Repetitive flame loss 100% Lockout
8 or 9 flashes Internal control 100% Lockout
Solid on Line voltage/Frequency Standby
Note: There is a one-second pause after each flash code.
Warning: Do not install the control in areas that can be exposed to dripping water,
steam cleaning, heavy dust, grease, or corrosive chemicals. If the controls can be
subjected to this type of environment, use a NEMA 4 rated enclosure to protect the
ignition control module.
If not properly protected from the above environment, the control will prematurely fail or
malfunction. Excessive high temperatures can damage the ignition control and cause
it to malfunction. Make sure the ambient temperature around the ignition does not
exceed the rated temperature for the control.

TROUBLESHOOTING GUIDE
1. No power up
•Faulty 24 VAC wiring
•Thermostat or transformer
•Faulty control
•Safety limits
2. Control LED is blinking RED
•Determine error code, refer to error codes (Table 5), also
refer to the troubleshooting flow chart in the installation
instructions
3. No spark during Trial for Ignition (TFI) time
•Faulty spark electrode wiring
•Spark gap too wide
•Faulty control
4. Burner does not light during trial for ignition time
•Faulty valve wiring
•Bad Gas Valve
•Faulty Control
5. Burner lights but gas valve turns off after TFI
•Weak flame, flame not in contact with the spark electrode of
flame sensor. Check that flame sensor tip is in the flame.
For proper sensing, the rod tip must be 3/8” (10mm) to 1/2”
(13mm) in the flame. See Figure 1.
•Dirty or corroded flame sensor
•Faulty flame sensor wiring
•Poor burner ground

FLAME CURRENT MEASUREMENT
Flame current of the device can be measured using a standard
microammeter by simply touching the meter leads to the 2 PIN labeled FC,
as shown in Figure 2.
•Flame current must be measured with flame lit and main gas
flowing
•Set meter to DC μAmp scale.
•Make sure meter leads are positioned correctly [+/-].
•Typical Flame Sense Current of 0.4 to 1.0 μAmp DC.
