Anleitung Zusammenfassung
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. 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 returns the burner to standby. IGNITION CARRYOVER. Once fl ame is 5. established, the ignition remains on for 10 seconds to ensure flame stability before turning off. If the control is wired for intermittent duty ignition, the ignition unit stays on the entire time the motor is running. RUN. The burner runs until the call for heat is6. satified. The burner is then sent to burner motor off delay, if applicable, or it is shut down and sent to standby.

Reversed polarity could cause erratic cycling of the burner control. Connect the wire from the RH or R terminal on the thermostat to the TR terminal on the control. Connect the wire from the W terminal on the thermostat to the TW terminal on the control. 0 Make connections to the control’s terminals as shown in Figures 8a and 8b. Refer to the label on the underside of the control for wiring details. 0 Note: Motor-off delay on a 7505P will be disabled if the safety and operating limits as shown in Figures 8a and 8b interrupt power to the control terminal L1. 0 Connect thermostat leads to the TR and TW terminals on the control or jumper the TR and TW terminals on the control, as directed by the appliance wiring diagram. -Thermostat anticipator Current: 0.1 amp -Thermostat voltage: 24 volts AC Note that if the thermostat short cycles or operates improperly, it may require an isolation relay for proper operation. The Beckett A/C Ready Kit (part no. 51950U) provides this function. Wiring instructions are included with the A/C Ready Kit. Start Up Burner and Set Combustion Hot Gas Puff-Back and Heavy Smoke Hazard Failure to prime the pump properly could result inunstable combustion, hot gas puff-back and heavysmoke. • Do not allow oil to spray into a hot combustion chamber while bleeding air from the pump. • Install a gauge in the nozzle discharge port tubing or fully open the pump bleed valve to prevent oil spray from accumulating in the combustion chamber during the air bleed procedure. • Ensure that all bubbles and froth are purged from the oil supply system before tightening the pump bleed valve. • Ensure that the appliance is free of oil and oil vapor before starting or resetting the burner. 1. Open the shutoff valves in the oil supply line to the burner. 2. Open the air dial. This is an initial air setting for the pump bleeding procedure only. Additional adjustments must be made with instruments. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. Set the thermostat substantially above room temperature. Close the line voltage switch to start the burner. If the burner does not start immediately you may have to reset the safety switch of the burner primary control. Priming the Pump Prepare the burner for priming by attaching a clear plastic hose over the bleed port fi tting and fully opening the pump bleed port. Use a suitable container to collect purged oil. Initiate a call for heat. After the burner starts, press and hold the reset button for 15 seconds until the yellow light turns on. This indicates that the button has been held long enough. Release the reset button. The yellow light will turn off and the burner will start up again. At burner start up, click the reset button while the igniter is still on. This will transition the control to a dedicated Pump Prime mode, during which the motor, igniter, and valve are powered for four minutes. The yellow light will be on. Bleed the pump until all froth and bubbles are purged. If desired, terminate the call for heat or hold the reset button for at least one second to exit Pump Prime mode and return to Standby. At the end of 4 minutes, the yellow light will turn off and the control will automatically return to standby mode. If prime is not established during the four minute pump prime mode, return to the previous steps to re-enter Pump Prime mode. Repeat Step 5 until the pump is fully primed and the oil is free of bubbles.. For R7184 primary controls, see part number 61351 or 61465, for special pump priming sequence. Prepare for combustion tests by drilling a 1/4” sampling hole in the flue pipe between the appliance and the barometric draft regulator.
