Sequence of Operation

BURNER STATES

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

2.Valve-On Delay (Prepurge): 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 fuel valve is opened. A flame should be established within the factory set trial for ignition time (“lockout time”).

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

•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.

RESET BUTTON OPERATION

•Table A explains what action the control will take when the reset button is pressed for different lengths of time during the various burner operating states.
