Honeywell R8184G4066 Protectorelay

The Honeywell R8184G4066 Protectorelay is a field-proven oil burner primary control designed for intermittent ignition systems. Built to manage the oil burner, oil valve, and ignition transformer simultaneously, this unit utilizes a solid-state flame sensing circuit for high-reliability monitoring. For technicians performing retrofits, this model serves as a direct professional cross-reference to replace White-Rodgers 668-601 units. It features a precise 15-second safety timing lockout, ensuring that the system shuts down quickly if the C554A cadmium sulfide flame detector fails to sense a flame. The terminal strip includes an integrated LED lockout indicator to streamline onsite diagnostics, while the manual trip lever allows contractors to safely disable the burner during routine maintenance. Designed for standard 4x4 junction box mounting, the R8184G4066 requires a 24 Vac thermostat and is rated for 7.4 A at 120 Vac, providing robust performance for residential and light commercial oil heating applications.

• Rapid Safety Response: Offers a 15-second lockout timing to minimize unburned fuel accumulation during ignition failure.
• Contractor-Friendly Diagnostics: Features an LED lockout status indicator and a manual trip lever for simplified troubleshooting and maintenance.
• Solid-State Reliability: Employs advanced flame sensing technology to ensure stable operation under variable environmental conditions.
• Universal Installation: Flexible mounting options allow for standard 4-inch junction box attachment or direct burner housing placement.
• Seamless Compatibility: Optimized for use with Honeywell C554A cad cells and standard low-voltage 24V thermostats.

What is the primary difference between the R8184G and R4184 models?
The R8184G is designed for use with low-voltage (24V) thermostats and includes an internal transformer, whereas the R4184 is intended for line-voltage thermostat applications.

Can this control replace a 30-second or 45-second lockout relay?
While the R8184G4066 provides a 15-second timing, you must ensure the burner manufacturer specifies a 15-second or longer timing to maintain safe operation. Replacing a shorter timing with a longer one is not recommended.

Does this unit support remote alarm notification?
Yes, this specific 4066 model includes alarm load ratings (75 VA at 120/240 Vac) specifically for connecting remote lockout signals or alarm systems.
