Sequence of Operation

▪

Burner States

▪

Standby: The burner is idle, waiting

1.

for a call for heat.

Valve-On Delay: The igniter and

2.

motor are on while the control delays
turning on the oil solenoid valve for
the programmed time.

Trial For Ignition: The oil solenoid

3.

valve is energized. A ame 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 ame being

established.

b. The cad cell detected ame at the

end of the Valve On Delay state.

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 qualied service

technician.

To reset from Hard Lockout, hold the

reset button for 15 seconds until the
yellow light turns on.

Ignition Carryover: Once ame is

5.

established, the igniter remains on for
10 additional seconds to ensure ame

stability.

Motor-off

delay

Run: The ame is sustained until the

6.

call for heat is satised. The burner
is then sent to Motor-Off Delay, if
applicable, or it is shut down and sent

to Standby.

Recycle: If the ame is lost while

7.

the burner is 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 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

ring chamber.

Motor-Off Delay: If applicable, the oil

8.

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

9.

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.

Reset Button Operation
