Run
: With a
fl
ame established and the control
continuing to detect a
fl
ame, the burner will operate
in the RUN Mode until the load demand is satis
fi
ed
or a limit opens.
If terminals RC1 and RC2 are jumpered, the
burner operates in the Low-High-Off Mode.
The burner starts at Low, goes to High after the
fl
ame stabilization period. Flame is extinguished
when the load is satis
fi
ed or a limit opens, and
the burner is sent to motor off delay.
If a high/low control has been wired between
terminals RC1 and RC2 the burner starts at
Low and is released to go High after the
fl
ame
stabilization period. It can repeatedly cycle
between low and high as necessary to meet
load demand until the load is satis
fi
ed or a limit
opens. The burner is then sent to Motor-off
Delay.
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
: 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.
