the igniter remains on for 10 additional seconds
to ensure
fl ame stability.
Run : The fl ame is sustained until the call for
heat is satis fi ed. The burner is then sent to
Motor-Off Delay, if applicable, or it is shut down
and sent to Standby.
Recycle : If the fl ame is lost while the burner is
fi ring, the control shuts down the burner, enters
a 60 second recycle delay, and repeats the
ignition sequence. The control will continue
to Recycle each time the fl ame is lost, until
it reaches a pre-set time allotment. The
control will then go into Hard Lockout instead
of recycle. This feature prevents excessive
accumulation of oil in the appliance fi ring
chamber.
Motor-Off Delay : If applicable, the oil solenoid
valve is turned off and the control delays
turning the motor off for the set motor-off delay
time before the control returns to standby.
Pump Prime: The igniter and motor are on with
the oil solenoid valve energized for 4 minutes.
During Pump Prime mode, the cad cell is
disregarded, allowing the technician to prime
the pump without having to jumper the cad cell.
