Resumen del manual
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.

Standby — The burner is idle, waiting for a call for heat. When a call for heat is initiated, there is a 3- to 10-second delay while the control performs a safe start check. Valve-on delay — As applicable, the ignition and motor are turned on for a 15-second prepurge. Trial for ignition (TFI) — The fuel valve is opened, as applicable. A fl ame should be established within the 15- second lockout time (30-second lockout time is available). Lockout — If fl ame 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. Call a qualifi ed service technician. Ignition carryover — Once fl ame is established, the ignition remains on for 10 seconds to ensure fl ame stability. It then turns off. Run — With a fl ame established and the control continuing to detect a fl ame, the burner will operate in the RUN Mode until the load demand is satisfi ed or a limit opens. If terminals RC1 and RC2 are jumpered, the burner operates in the Low-High-Off Mode. The burner starts at Low, goes to High after the fl ame stabilization 1. 2. 3. 4. 5. 6. a. period. Flame is extinguished when the load is satisfi ed or a limit opens, and the burner is sent to Motor-Off Delay. If a high/low control has been wired between terminals RC1 and RC2 the burner starts at Low and is released to go High after the fl ame stabilization period. It can repeatedly cycle between low and high as necessary to meet load demand until the load is satisfi ed or a limit opens. The burner is then sent to Motor-off Delay. Recycle — If the fl ame is lost while the burner is fi ring, the control shuts down the burner, enters a 60-second recycle delay, and then repeats the ignition steps outlined above. If the fl ame is lost three times in a row, the control locks out to prevent continuous cycling with repetitious fl ame loss caused by poor combustion. Burner motor-off delay — The fuel valve is closed and the burner motor is kept on for the selected postpurge time before the control returns the burner to standby. Cad Cell Resistance Indicator: During the burner run state, click the reset button (less than 1 second) to check the cad cell resistance range. The yellow light will fl ash 1 to 4 times, depending on the amount of light detected by the cad cell. See Figure 15 for Sequence of Operation illustration.

A qualified service technician should be called to inspect the burner.
