RECEPTACLE
1. STANDBY. The burner is idle, waiting for a call for
heat. When a call for heat is initiated, there is a 3-
10 second delay while the control performs a safe
start check.
2, VALVE-ON DELAY. The ignition and motor are
turned on for a 15 second valve-on delay.
3. TRIAL FOR IGNITION (TFI). The fuel valve is
opened. A flame should be established within the
15 second lockout time.
4. LOCKOUT. If flame is not sensed by the end of
the TFI, the control shuts down on safety lockout
and must be manually reset. If the control locks out
three times in a row, the control enters restricted
lockout.
5. IGNITION CARRYOVER. Once flame is estab-
lished, the ignition remains on for 10 seconds to
ensure flame stability before turning off. If the con-
trol is wired for intermittent duty ignition, the ignition
unit stays on the entire time the motor is running.
6. RUN. The burner runs until the call for heat is sati-
fled. The burner is then sent to burner 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 then repeats the above
ignition sequence. If flame is lost three times in a
row, the control locks out to prevent cycling with
repetitious flame loss due to poor combustion.
8. BURNER MOTOR-OFF DELAY. The fuel valve
is closed and the burner motor is kept on for the
selected motor-off delay time before the control re-
turns the burner to standby.
