4. ການຕິດຕັ້ງແລະການຕິດຕັ້ງ

Installation of the R7284B1024 Electronic Oil Primary should only be performed by a qualified HVAC technician. This control is designed for wall mounting.

1. ການຕັດການເຊື່ອມຕໍ່ໄຟຟ້າ: Ensure all power to the oil burner system is disconnected at the main service panel before beginning installation.
2. ການຕິດຕັ້ງ: Mount the R7284B1024 control securely to a wall or suitable surface using appropriate fasteners. Ensure it is in an accessible location for future servicing and visibility of the LED indicator.
3. ສາຍໄຟ: Connect the control to the oil burner system components (motor, igniter, oil valve, limit controls, thermostat) according to the wiring diagram provided with the product packaging. Pay close attention to line voltage connections (120 VAC, 60 Hz).
4. ການຕິດຕັ້ງເຊັນເຊີ: Install the flame sensor (cad cell) in the burner blast tube as per the burner manufacturer's instructions, ensuring it is properly positioned to detect flame.
5. ການຟື້ນຟູພະລັງງານ: Once all connections are secure and verified, restore power to the system.

5. ຄໍາແນະນໍາການດໍາເນີນງານ

The R7284B1024 operates automatically in conjunction with the thermostat and other system controls. It features a button control for specific functions, typically for reset or diagnostic modes.

• ການ​ດໍາ​ເນີນ​ງານ​ປົກ​ກະ​ຕິ​: When a call for heat is initiated by the thermostat, the control performs a Safe Start Check. If conditions are met, it proceeds with the ignition sequence.
• ລຳດັບການຕິດໄຟ: The control provides power to the igniter and oil valve. If a flame is not established within the 15-second safety switch timing, the control will lock out.
• On-Delay: The fixed 15-second on-delay is an integral part of the control's operational logic, managing specific timing requirements during the burner cycle.
• Resetting Lockout: If the control enters a lockout state (indicated by the LED), press the reset button on the control. If the burner fails to start after multiple resets, refer to the Troubleshooting section.

6. ການວິນິດໄສ ແລະ ການແກ້ໄຂບັນຫາ

The R7284B1024 features an LED indicator that provides diagnostic information to assist in troubleshooting. The LED will display specific flash codes to indicate the status or fault condition of the control.

• ສະຖານະພາບ LED: Observe the LED on the control. A steady light typically indicates normal operation or a specific stage in the burner cycle. Flashing patterns indicate diagnostic trouble codes (DTCs).
• ຕົວຊີ້ບອກການລັອກ: If the control locks out, the LED will typically flash a specific code indicating the reason for lockout (e.g., no flame detected within safety timing).
• Interpreting Codes: Refer to the detailed diagnostic code chart in the full product documentation for specific interpretations of LED flash patterns. This chart will guide you in identifying the root cause of operational issues.
• ບັນຫາທົ່ວໄປ: If the burner fails to start or locks out, check for:
  • ບໍ່ມີອຳນາດໃນການຄວບຄຸມ.
  • Faulty flame sensor (cad cell).
  • No oil supply.
  • Ignition system failure.
  • Thermostat not calling for heat.
