This setting is often referred to as “pre-purge”. Note: Ifflame is sensed during valve delay on, control will lockout immediately (except when Valve Delay On is set to 0 or 3 seconds).remains blocked for 20 seconds. Following any shutdown, theburner will be permitted to recycle 3 times following a 1 minutedelay. Lockout occurs if the blockage persists throughout 3recycles during any single call for heat. Trial for Ignition: Flame-establishing period during ignition.45 sec TFI up to 3 GPH15 sec TFI up to 19.9 GPH* If “no valve” is selected in setup, the air intake cannot bechecked prior to TFI. In this case, the burner will only shutdown following the 20 second blockage described above. Forall burners with valves, Valve Delay settings of less than 15Seconds will be automatically changed to 15 Seconds to allowfor the prepurge test. Motor Delay Off: Time period the motor is on after the Call forHeat is satisfied to allow for evacuation of combustion gases. Thissetting is often referred to as “post-purge”. A call for heat duringMotor Delay Off will result in a recycle. Note: If Valve Delay On isset to “0 Seconds” or “No Valve”, Motor Delay Off can only be setto “0 Seconds”.Exhaust: When the appliance is equipped with a blocked ventswitch, the “Exhaust” setting should be selected. If a blockedvent is detected during burner startup, the Pro X 70200 controlwill NOT respond to the blocked intake vent until 30 secondsafter the ignition sequence is complete (following Flame Stabilization), if the vent remains blocked at that time, the burnerwill shutdown and lockout. If the vent is not blocked duringthis startup test, but becomes blocked during normal burneroperation, the burner will shut down and recycle, depending onthe Allowed Recycles selected. Lockout occurs if the blockagepersists and the Allowed Recycles setting is reached during anycall for heat. Flame Stabilize: The time period after Trial for Ignition that theignitor remains on to stabilize flame. CAD Ohms Max: The maximum Ohms range that the control willallow the burner to operate. Ignition TypeInterrupted: Spark is turned off after Flame Stabilization period.Smart Ignition: If flame is lost at any time after the FlameStabilization period, the control will recycle (60 - 65 seconds).Following this recycle, the control will operate in IntermittentDuty mode (ignition on throughout the call for heat) for ten heatcycles. Following these ten cycles, the control will revert back toInterrupted Duty and will remain in Interrupted Duty until anotherrecycle event occurs.NOTE: If the Pro-X 70200 is being connected to both a combustion air proving switch and blocked vent switch, call CarlinTechnical Support for assistance. Allowed Recycles: Number of Recycles allowed during a singleCall for Heat prior to lockout. Clear Fault History: Allows all prior burner fault conditions storedin control to be cleared. TT Jumpered: Allows TT to be “jumpered” by software program. Vent Input: Applicable only to applications equipped with acombustion air proving switch (Intake) or a blocked vent switch(Exhaust): Restore Factory Defaults: Allows all factory defaults to berestored in control (refer to settings shaded in gray in the tableabove). Will reset and reboot control and require answer to “solenoid valve” question at startup.Intake: When the burner is equipped with a combustion airproving switch, the “Intake” setting should be selected. Ateach burner startup, the control will check the air intake duringpre-purge (Valve On Delay)*. If the air is blocked, the control willabort pre-purge and shutdown the burner. If the air intake is notblocked during this startup test, but becomes blocked duringnormal burner operation, the burner will shut down if the airCarlin Combustion Technology, Inc. Per UL requirements, the control will not turn on if thecad cell senses flame (light) during the self-test. If thecad cell sees flame, the control will remain in self-testmode until the cad cell no longer senses flame.5MN70200B 062819

Operating SequenceNOTE: Push View Ohms button anytime during burner operation to view the CAD Ohms reading.With power to the control and all manual oil line valves open,set thermostat (and limit) to call for heat. NOTE: The thermostat circuit must be closed and power must be coming toblack wire from limit circuit.Flame Stabilize X X SecWhen the Flame Stabilize timer expires, the ignitor will turnoff and the burner will continue to fire until the Call for Heatends or the limit string opens. The screen will display “BurnerRunning”. Note: If Smart Ignition is selected in the SetupMenu, the screen will alternate between “Burner Running”and “Smart Ign Active” at any time the ignitor is running inintermittent mode.Pre-Ignition X X SecFollowing a 3 sec Pre-Ignition, the control advances to ValveDelay On –Valve Delay On X X SecBurner Running 5 9 SecDuring Valve Delay On, motor starts. After set timing, valveopens and the control advances to Trial for Ignition when thecountdown clock expires. NOTE: For the Valve Delay to operate, the burner must be equipped with a solenoid valve that iswired to the violet terminal.When the Call for Heat ends (or a limit control interrupts theburner circuit), the oil valve (if installed) will turn off within2 seconds. The motor remains on for the Motor Delay Offperiod. When the Motor Delay Off timer expires, the controlreturns to Standby mode awaiting the next call for heat.Trial for Ign X X SecMotor Delay Off X X SecDuring Trial for Ignition, the CAD cell must sense flame orthe control will go into lockout.

Service and TroubleshootingBurner 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 seeresidual hot spots in chamber. To troubleshoot, press the Gbutton to display cad cell Ohms. Dark resistance should beover 50,000 ohms and room light resistance (control flippedopen) should be less than 10,000 ohms. Replace cell ifnecessary, or reinstall and close the burner housing. Checkfor stray light by measuring the CAD cell resistance lookinginto the inactive combustion chamber. It should read greaterthan 50,0000 ohms.Last Fault Display: When the control is reset from a lockoutcondition, if the burner resumes normal operation, the screenwill toggle the last fault and its cause for five days (longer duration if control is not wired for constant power). This featureis designed to allow the service technician to easily see whatcaused the condition in the event the homeowner reset thecontrol prior to his arrival. The screen will alternate betweendisplaying what the last fault w
