Protectorelay Oil Burner Relay with Lock Out Timing

Honeywell R8184G4009 – Protectorelay® Primary Control for Oil Burners

The Honeywell R8184G4009 Protectorelay® is a line voltage primary safety control designed for use with oil-fired heating equipment. This unit functions as a burner primary control, providing switching and flame monitoring for systems with intermittent ignition and solenoid valves. It is engineered for single-stage oil burners with cad cell flame detection.

This control includes safety timing, manual reset on safety lockout, and LED lockout indication at the terminal block. It is commonly installed in forced warm air furnaces, boilers, and other hydronic heating applications requiring dependable flame safeguard and oil burner management.

Application Features

• Primary Burner Control – Controls burner motor, ignition transformer, and solenoid valve during heat call
• Flame Monitoring – Solid-state circuitry detects cadmium sulfide (cad cell) flame sensor signal for flame presence
• Safety Shutdown – Locks out after failed ignition or flame loss; requires manual reset to restore operation
• LED Diagnostic – Lockout indicator provides visual fault signal for easy troubleshooting
• Reset Capability – Top-mounted manual reset button for reactivation following lockout event
• Mounting Versatility – Fits standard 4” junction box or mounts directly to burner housing with provided screws

Installation Guidelines

For best results, install in accordance with local codes and applicable safety standards. The R8184G4009 mounts on a 4" x 4" junction box or directly to the burner chassis. Wiring must follow burner manufacturer and control specifications. Ensure cad cell sensor is properly positioned for accurate flame detection. This product is intended for use by qualified technicians only.

Professional Considerations

• Compatible with conventional oil primary applications using cad cell sensors
• Manual reset ensures safety following flame loss or ignition failure
• Flame failure shutdown minimizes risk of unburned fuel discharge
• Reliable solid-state flame sensing reduces maintenance frequency

Summary
