The Honeywell R7795A1001 is a flame safeguard primary control unit designed for providing reliable flame failure protection and automatic control of commercial and industrial gas and oil burners. It features a solid-state design, offering enhanced durability and reliability in harsh environments. This model supports both intermittent pilot and interrupted pilot systems, providing flexibility for various applications. It incorporates an ultraviolet (UV) amplifier for flame detection, ensuring quick and accurate flame sensing.
The R7795A1001 operates at 120 Vac and consumes a maximum of 17 VA. It includes a field-selectable trial for pilot flame ignition, allowing either a ten-second or a four-second trial period, enhancing the system’s adaptability. The unit is equipped with a safe-start feature to prevent startup if a flame or flame-simulating failure is detected, ensuring safety and compliance with Underwriters Laboratories and Factory Mutual standards.
Additionally, the R7795A1001 features a powered alarm terminal that can operate an external line voltage alarm in the event of a safety lockout. It mounts on a Q795A Subbase with two captive screws, simplifying installation and ensuring secure connections. The system also includes terminals for connecting a line voltage airflow switch to verify airflow throughout the prepurge and run periods, further enhancing operational safety and reliability.
