The Honeywell Primary Control Cross Reference Guide serves as a comprehensive resource for professionals seeking to upgrade or replace legacy burner controls with modern Honeywell systems. This guide facilitates the transition from older models to contemporary solutions by providing detailed cross-references and wiring information.
Ordering Guide
Cross-Reference Overview:
The guide systematically matches obsolete or less common controls to current Honeywell models, particularly focusing on the 7800 Series—a microprocessor-based integrated burner control platform suitable for single-burner applications. For example, devices like the R177A, R180A, and R187A are recommended to be replaced with the RA890F model. Further modernization can be achieved by transitioning to the RM7890A1015 from the 7800 Series. This upgrade enhances functionality and reliability in burner management systems.
Wiring and Subbase Requirements:
Upgrading to newer models often necessitates changes in wiring configurations and subbases. The guide specifies that replacing certain models with the RA890F requires the Q270A Subbase, while transitioning to the RM7890A1015 necessitates the Q7800F1004 Subbase. These specifications ensure compatibility and optimal performance of the new controls.Honeyvell Energy
Detailed Replacement Tables:
The document includes extensive tables that detail the specifications of various models, such as operating voltage, frequency, safety switch timing, flame failure response time, and the presence of alarm contacts. For instance, the RA890E series has multiple variants with differing specifications, each mapped to a suitable replacement in the 7800 Series. This detailed information aids professionals in selecting the appropriate replacement that matches their system requirements.
Modernization Wiring Information:
Transitioning to modern controls like the RM7890A1015 may require rewiring existing systems. The guide emphasizes the importance of consulting the Modernization Wiring Information section to ensure proper installation and integration. This section provides insights into adapting current wiring setups to accommodate new control modules, thereby ensuring safety and functionality.
Footnotes and Additional Considerations:
The guide includes footnotes highlighting critical considerations, such as selecting the appropriate voltage, frequency, and timing specifications when choosing replacement controls. It also advises on the selection of compatible flame amplifiers, like the R7847A1025, R7847A1033, R7847B1023, or R7847B1031, depending on the specific application. These details are crucial for ensuring the seamless operation of upgraded burner management systems
