WARNINGS
1. Warning – Do not attempt to confirm combustion simply by inspecting the flame visually. You must use combustion test instru-
ments. Failure to properly verify/adjust combustion could allow unsafe operation of the burner, resulting in severe personal injury,
death or substantial property damage. Refer to the burner manual for proper setup instructions.
2. Warning – Never test an ignitor by placing a screwdriver (or other metallic object) across the high voltage clips. Check ignitors only
by observing spark at appliance ignition electrodes, with fuel supply OFF. Using any other method could cause ignitor damage and
severe personal injury.
3. Danger – Fire, explosion, or carbon monoxide hazard. Water damage can lead to unreliable operation or cause the control to
malfunction which could lead to severe personal injury or death. Do not install the control module where it can get wet. Always
replace the control if it gets wet or if it has any signs of water residue.
4. Warning – Electrical shock hazard. To prevent electrical shock, death, or equipment damage, disconnect power supply before
installing or servicing control. Only qualified personnel may install or service this control in accordance with local codes and ordi-
nances. Read instructions completely before proceeding.
5. Warning – Electrical shock hazard. The ignition circuit of the control can produce over 10,000 volts which can cause severe injury
or death.
6. Warning – Frozen pipes/water damage. Central heating systems are prone to shut down as a result of power or fuel outages,
safety related fault conditions or equipment failure. Installation of freeze protection monitoring or other precautions are recommend-
ed for unattended dwellings in climates subject to sustain below—freezing temperatures.
7. Warning – All work must be performed by a qualified and licensed professional in accordance with all applicable codes and ordi-
nances.

AVAILABLE SETTINGS
Setup Menu Definitions
•Valve Delay On: Time period motor and ignitor are on
prior to Trial for Ignition. This setting is often referred to as
“pre-purge”. Note: If flame is sensed during valve delay on,
control will lockout immediately.
• Trial for Ignition: Flame-establishing period during ignition.
Note: Do not use 45 TFI for burners larger than 3GPH.
• Motor Delay Off: Time period the motor is on after the Call
for Heat is satisfied to allow for evacuation of combustion
gases. This setting is often referred to as “post-purge”. A
call for heat during Motor Delay Off will result in a recycle.
Note: If Valve Delay On is set to “0 Seconds” or “No Valve”,
Motor Delay Off can only be set to “0 Seconds”.
• Flame Stabilize: The time period after Trial for Ignition that
the ignitor remains on to stabilize flame.
• CAD Ohms Max: The maximum Ohms range that the con-
trol will allow the burner to operate.
• Ignition Type
Interrupted: Spark is turned off after Flame Stabilization
period.
Smart Ignition: If flame is lost at any time after the Flame
Stabilization period, the control will recycle (60 - 65 sec-
onds). Following this recycle, the control will operate in
Intermittent Duty mode (ignition on throughout the call for
heat) for ten heat cycles. Following these ten cycles, the
control will revert back to Interrupted Duty and will remain
in Interrupted Duty until another recycle event occurs.
• TT Jumpered: Allows TT to be “jumpered” by software
program.
• Vent Input: Applicable only to applications equipped with
a com¬bustion air proving switch (Intake) or a blocked vent
switch (Exhaust): The Intake setting has a 10 second delay
before shut¬ting down in the event the air intake is blocked.
The burner will recycle (subject to the Allowed Recycles
setting). The Exhaust setting allows for a 30 second delay
after flame is proven at each burner start up. If the vent is
blocked at the conclusion of the 30 second delay, the burn-
er will shut down and lock-out immediately. If the vent is not
blocked at start-up, but becomes blocked sometime after
the 30 delay, the burner will shut down immediately, but will
be allowed to recycle (subject to the Allowed Recycles set-
ting). Note: The above assumes the blocked vent switch is
not equipped with its own lock-out feature.
• Allowed Recycles: Number of Recycles allowed during a
single Call for Heat prior to lockout.
• Clear Fault History: Allows all prior burner fault conditions
stored in control to be cleared.
• Restore Factory Defaults: Allows all factory defaults to
be restored in control (refer to settings shaded in gray in
the table above). Will reset and reboot control and require
answer to “solenoid valve” question at startup.
Per UL requirements, the control will not turn
on if the cad cell senses flame (light) during the
self-test. If the cad cell sees flame, the control
will remain in self-test mode until the cad cell no
longer senses flame.

Operating Sequence
With power to the control and all manual oil line valves open,
set thermostat (and limit) to call for heat. NOTE: The ther-
mostat circuit must be closed and power must be coming to
black wire from limit circuit.
Following a 3 sec Pre-Ignition, the control advances to Valve
Delay On –
During Valve Delay On, motor starts. After set timing, valve
opens and the control advances to Trial for Ignition when the
countdown clock expires. NOTE: For the Valve Delay to oper-
ate, the burner must be equipped with a solenoid valve that is
wired to the violet terminal.
During Trial for Ignition, the CAD cell must sense flame or
the control will go into lockout. When flame is detected, the
screen will briefly display “Flame Detected” and then return
to the “Trial for Ign”. When the countdown timer expires, the
control advances to Flame Stabilization
NOTE: Push View Ohms button anytime during burner opera-
tion to view the CAD Ohms reading.
When the Flame Stabilize timer expires, the ignitor will turn
off and the burner will continue to fire until the Call for Heat
ends or the limit string opens. The screen will display “Burner
Running”. Note: If Smart Ignition is selected in the Setup
Menu, the screen will alternate between “Burner Running”
and “Smart Ign Active” at any time the ignitor is running in
intermittent mode.
When the Call for Heat ends (or a limit control interrupts the
burner circuit), the oil valve (if installed) will turn off within
2 seconds. The motor remains on for the Motor Delay Off
period. When the Motor Delay Off timer expires, the control
returns to Standby mode awaiting the next call for heat.

Service and Troubleshooting
Last Fault Display: When the control is reset from a lockout
condition, if the burner resumes normal operation, the screen
will toggle the last fault and its cause for five days (longer du-
ration if control is not wired for constant power). This feature
is designed to allow the service technician to easily see what
caused the condition in the event the homeowner reset the
control prior to his arrival. The screen will alternate between
displaying what the last fault was and displaying how to clear
the message hold ESC for 3 seconds.
Display Voltage and Current: Press + for 3 seconds to
display real time voltage and current.
Lockout: If lockout occurs, the screen turns on, the fault icon
flashes and a fault message is displayed on the screen. To
Reset Push in and hold the red Reset button for 1 second,
then release. NOTE: Recycling power to the control will not
reset it from it from a lockout condition.
Two fault conditions result in an immediate lockout. These
include; Flame detected during pre-purge and flame failure
during Trial for Ignition. All other faults will result in a Recycle
(unless the Allowed Recycles is set to ‘None’ in the Set-up
Menu). A Recycle results in the burner shutting down for 60
seconds then resuming operation in Standby (if there is no
Call for Heat) or initiating the Operating Sequence above (if
there is a Call for Heat).
Latch-up: If the control locks out 3 times during a single Call
for Heat, Latch-Up will be displayed on screen.
To Reset the control after latch-up, press and hold the red
Reset button for 30 seconds. WARNING: Only a qualified
service technician should attempt to reset the control
after latch-up. The problem that caused the repeat lock-
outs must be corrected before returning the burner to
normal operation. NOTE: Recycling power to the control will
not reset it from it from a latch-up condition.

FROZEN PIPES/WATER DAMAGE
This is not a freeze protection device. Suitable freeze protection monitoring or other precautions are recommended to protect against
ruptured pipes/water damage caused by fuel outage, safety related fault conditions or equipment failure.
Burner will not fire
• Check line voltage to the control (at least 102 vac).
• Check all electrical connections.
• Is CAD cell seeing light?
• Light is leaking into the burner housing
• CAD cell is defective
• There is a problem with the CAD cell wiring or holder
• If appliance was recently shut down, CAD cell may see
residual hot spots in chamber. To troubleshoot, press the G
button to display cad cell Ohms. Dark resistance should be
over 50,000 ohms and room light resistance (control flipped
open) should be less than 10,000 ohms. Replace cell if
necessary, or reinstall and close the burner housing. Check
for stray light by measuring the CAD cell resistance looking
into the inactive combustion chamber. It should read greater
than 50,0000 ohms.
Other no start problems:
• Valve lead voltage on too early. Correct bad connection.
• Motor relay welded. If valve has no voltage, and line voltage
is okay (102 - 132 VAC), the issue is a welded motor relay.
Replace the control.
• Motor current less than 0.2 Amps.
Blocked vent – not recycling:
• Recycle only works on non-manual reset vent switch
Repeated flame failures
• CAD cell is defective. Replace.
• Air leaking into oil line causing flame out – check oil line
connections and filter gasket.
• Defective nozzle causing flame to be erratic – change
nozzle.
• Excessive airflow or draft causing flame to leave burner
head. Check for proper air band setting and draft.
• Excessive back pressure causing flame to be erratic –
check appliance and flue for sooting/plugging.
Control locks out at end of TFI
• No oil to burner – check oil supply, filters, lines.
• Shorted electrodes – inspect for cracked porcelain and
replace as needed.
• Poor spark – check electrode spacing and condition per
burner manual. Replace or realign if necessary.
• Nozzle clogged – replace nozzle.
• Airflow too high – check air band setting.
• Ignitor module defective – replace if no spark.
• CAD cell defective.
• Oil valve (if used) stuck in closed position.
• Check wiring connections.
