Carlin Combustion Technology 4223002s Cad Cell Oil Primary Control 30 Second Tfi Interrupted Duty

Product Description

The Carlin Combustion Technology 4223002s is a CAD cell oil primary control designed for interrupted duty operation on residential and light commercial oil-fired heating systems. This recycle-type electronic control mounts directly on top of standard flame retention oil burners, making installation straightforward for HVAC technicians and heating contractors. It uses a cadmium sulfide (CAD) cell flame detector to monitor burner operation and provide reliable ignition sequencing with a 30-second trial for ignition period. The 4223002s is compatible with most standard oil burner setups and works alongside thermostats and aquastats, giving service professionals flexibility across a wide range of heating equipment. The control features an oil pump bleed assist function that supports up to 1 minute of pump priming, which is especially useful during initial startup or after filter changes. Diagnostic LEDs for status, lockout, and flame detection allow technicians to quickly read system conditions without additional test equipment, speeding up service calls. The recycle-on-flame-failure feature allows the burner to make additional ignition attempts before entering lockout, reducing nuisance service calls on systems with marginal flame conditions. A serviceman reset protection function latches the control after 3 consecutive lockouts, preventing repeated unsafe restart attempts without a qualified technician inspecting the system. The improved SMC technology eliminates bleed voltage during standby, which protects connected components and improves system accuracy. The flame stabilize feature ensures consistent and accurate flame recognition, reducing false lockouts. This control is also rated for use with generator power and is insensitive to frequency changes, making it a dependable choice in off-grid or backup-power heating applications. Power input is 120 VAC at 60 Hz, and the unit is UL recognized for use in the United States and Canada.

• Recycle-type operation with 30-second trial for ignition and recycle on flame failure
• Diagnostic LEDs for status, lockout, and flame detection speed up troubleshooting
• Oil pump bleed assist up to 1 minute supports reliable startup and priming

Product Highlights

The Carlin Combustion Technology 4223002s CAD cell oil primary control delivers reliable, interrupted duty burner operation with advanced flame monitoring, serviceman protection, and generator compatibility for oil-fired heating systems.
