RM7890A1015 Honeywell Burner Control

Product Overview

The Honeywell RM7890A1015 Burner Control is a microprocessor-based flame safeguard / primary burner control module designed for safe, reliable burner operation in gas, oil, or combination fuel systems. Ideal for single-burner applications demanding high safety, diagnostics, and automation. Compatible where specifications call for intermittent pilot and optional shutter drive control.

Key Features & What Sets It Apart

• Automatic burner sequencing including pilot ignition, flame supervision, and lockout if flame fails

• Intermittent pilot system with choice of a 4-second or 10-second pilot flame establishing period

• Five status LEDs for clear diagnostics, plus nonvolatile memory preserving operation history after power loss

• Optional local or remote annunciation, remote reset capability, and expanded diagnostic display modules

• Designed for reliability and safety, with upstream/shutter drive compatibility (if your system requires shutter drive or auto control bus options)

Technical Specifications

Applications & Compatibility

This control module is suited for:

• Commercial and industrial boilers, furnaces, ovens, and process heating systems

• Systems requiring intermittent pilot devices

• Installations needing advanced diagnostics, memory retention, and optional accessories (display modules, remote reset etc.)

• Environments where safety codes demand flame monitoring, lockout, and system sequencing

Benefits for You

• Enhances site safety by ensuring flame presence and automatic lockout if flame is lost

• Reduces maintenance time thanks to diagnostic LEDs and memory of fault conditions

• Provides installation flexibility with optional accessories and remote modules

• Built to withstand harsh operational environments and maintain consistent performance

FAQ

• What is “intermittent pilot” vs. “continuous pilot”?
  Intermittent pilot means the pilot light fires only during system start or when needed rather than burning continuously, saving fuel and reducing wear.

• What is a shutter drive? Do I need it?
  A shutter drive is an accessory for applications that require the burner to control airflow via a shutter or damper. If your system includes or needs a shutter drive, verify compatibility with RM7890A1015 or add the optional module.

• What do the 5 LEDs indicate?
  They show sequence status and fault diagnostics so that installers and maintenance staff can quickly see where in the burner ignition or flame detection process a problem is occurring.

• How do I know if RM7890A1015 is compatible with my burner?
  Check that your system requires On-Off primary control, intermittent pilot, 120Vac power, and whether accessories like remote reset or display modules are needed. If in doubt, compare it to your current control or consult technical support.
