Resideo R8184G4066 Cad Cell Primary Control Relay 15 Second Lockout

The Resideo by Honeywell R8184G4066 is a reliable cad cell primary control designed for oil-fired heating systems. This control provides critical flame sensing and burner management with a 15-second safety lockout timing to protect against unsafe operating conditions.

Key Features:

• 15-second lockout timing for rapid safety response
• Cad cell flame detection technology for reliable sensing
• Primary control relay for oil burner systems
• Manual reset required after safety lockout
• Durable construction for long service life
• Direct replacement for compatible Honeywell/Resideo systems

This primary control is designed for residential and light commercial oil heating applications. The cad cell sensor monitors flame presence during burner operation, and if flame is not established within the safety timing period, the control locks out and requires manual reset to prevent unsafe conditions. Essential for HVAC technicians servicing oil-fired furnaces and boilers.
