Sequence of Operation

WARNING Fire Hazard

Reset and Service by Qualified Technician only.

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.The pre-set time allotment for relighting is exceeded.

d.Failed welded relay check.

If the control detects a welded motor contact, the motor only will cycle 5

seconds on, 5 seconds off, 3 times before locking out.

To reset the control from lockout interrupt power for at least 2 seconds.

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 control then switches to Motor-Off Delay,

if applicable, or it shuts down and returns to Standby.

7.Relight: If the flame is lost while the burner is firing, the control immediately repeats the ignition sequence. The control will continue to Relight each time the flame is lost, until it reaches a pre-set time allotment. The control will then

go into Lockout instead of Relight. This feature prevents excessive accumulation of oil in the equipment’s combustion 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. Note that to utilize the motor off delay, power must remain to the red wire after the call for heat ends. (Enable input turned off, see Figure 2.)
