It interfaces with a Pyrostat® flame detector to sense temperature changes in flue gases up to 1000°F, ensuring accurate detection of flame presence and proper system operation. The control features a built-in safety switch that interrupts burner operation after 75 seconds if ignition fails, requiring manual reset to restart operation—providing added protection against unsafe conditions. Designed for use with either line-voltage or 24 VAC control circuits, the RA116A1055 is compatible with a wide range of commercial and residential oil burner systems. Its flange mount allows easy installation on both curved and flat surfaces, making it adaptable for varied burner configurations. Key Features: Integrated Flame Safeguard and Control: Combines burner cycling control and flame detection into one reliable unit. 75-Second Safety Switch Timing: Provides timed safety lockout to prevent unsafe burner operation after ignition failure. Manual Reset Safety Feature: Requires user reset following safety lockout, ensuring controlled and deliberate burner reactivation. Pyrostat® Flame Detection Compatibility: Works with Honeywell Pyrostat® sensors for accurate monitoring of flue gas temperatures up to 1000°F (556°C). Flange Mount Design: Allows versatile installation on both curved and flat mounting surfaces for system flexibility. Dual Circuit Compatibility: Operates with line-voltage or 24 VAC control systems for universal HVAC integration. Manual Trip Safety Switch: Enables burner shutdown during maintenance or servicing for improved safety. Heavy-Duty Construction: Built with a robust metal housing for durability and long operational life in harsh burner environments. Reliable Ignition Sequencing: Supports intermittent ignition systems for efficient oil burner performance. Service-Friendly Layout: Provides easy access to manual reset controls and wiring terminals for simplified maintenance.
