Sequence of Operation

Burner States

1.Standby: The burner is idle, waiting for a call for heat.

2.Valve-On Delay: The igniter and motor are on while the control delays turning on the oil solenoid valve for the programmed time.

3.Trial For Ignition: The oil solenoid valve is energized. A flame should be established within the factory set trial for ignition time (“lockout time”).

4.Lockout: The control has shut down for one of the following safety reasons:

a.The trial for ignition (lockout) time expired without flame being established.

b.The cad cell detected flame at the end of the Valve On Delay state.

c.Flame is lost while the burner is firing and the pre-set time allotment is expired. See “Recycle” (Item 7).

To reset the control from lockout click the button 1-second.

NOTE: A recurrence of the above failure modes or a failed welded relay check could cause the control to enter a Hard Lockout state that must be reset only by a qualified service technician.

To reset from Hard Lockout, hold the reset button for 15 seconds until the yellow light turns on.

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, 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 repeats the ignition sequence. The control will continue to Recycle each time the flame 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 firing chamber.

8.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.

9.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.
