Switch #1 - Recycling Mode
With this switch in the “ON” position, the burner will recycle the ignition sequence once during each drying cycle after a burner fan air switch or main flame failure, but only if the failure occurs more than
Switch #2 - Intermittent Pilot
This switch is “ON” for intermittent pilot or “OFF” for interrupted pilot. ADC utilizes intermit tent pilot so that the pilot flame stays lit during the entire drying cycle. With interrupted pilot, the pilot flame would go out once the main flame is established. This is used mainly on oil burners lit by a gas pilot.
Switch #3 - Trial for Ignition (TFI) Time
When this switch is “ON” a Trial for Ignition (TFI) of ten (10) seconds is set. If it is in the “OFF” position, the TFI is five (5) seconds. The Trial for Ignition Time is the length of time that the pilot is given to light. A ten (10) second TFI is best for the dryer.
