• The trial for ignition (lockout) time expires
without flame being established.
• The cad cell detects flame during Valve-On
Delay.
• The Recycle mode 30-second time budget
expires (see “Recycle” section for complete
explanation of recycle time budget).
If the control locks out three times without
completing a successful call for heat, the control
enters Restricted (Hard) Lockout, and must be reset
by a technician. Hold the reset button for 15
seconds until the red light shuts off to reset from
Restricted Lockout.
5. Ignition Carryover: Once flame is established,
the igniter remains on for 10 additional seconds
to ensure flame stability.
6. Run: The flame is sustained until the call for
heat is satisfied. The burner is then sent to
Motor-Off Delay (Postpurge), if applicable, or it
is shut down and sent to Standby.
7. Recycle: If the flame is lost while the burner is
firing, the control shuts down the burner, enters
a 60-second recycle delay and then repeats the
ignition sequence. The control will continue to
Recycle each time the flame is lost until the
accumulated oil-flow-without-flame time
reaches 30 seconds, at which point the control
will go into lockout. This feature prevents
excessive accumulation of oil in the appliance
firing chamber.
8. Motor-Off Delay: If applicable, the fuel valve is
closed and the control delays turning the motor
off for the set motor-off delay time before the
control returns to standby.
9. Pump Prime: The igniter and motor are on with
the oil valve open for up to 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.

will take when the reset button is pressed for
