Honeywell rm7895b1013/u On-off Primary Burner Control

Product Description

The HONEYWELL rm7895b1013/u is a microprocessor-based integrated burner control designed for industrial single-burner applications. It manages on-off firing sequences for gas, oil, coal, or combination fuel systems, providing safety supervision beyond what conventional controls offer. The control operates at 120 volts and supports an intermittent pilot ignition sequence with selectable interlocks for flexible system configuration. A shutter drive output, valve proving feature, and blinking LED fault annunciation are built in, allowing technicians to diagnose faults quickly during commissioning or service calls.

This control is suited for industrial and commercial semi-automatically fired burner systems. The prepurge sequence clears the combustion chamber before ignition, reducing the risk of unburned fuel accumulation. The intermittent pilot setup means the pilot lights only on demand and shuts off after main flame is established. Selectable interlocks allow the control to be configured to match the specific safety requirements of the burner system it serves. Licensed burner technicians and industrial HVAC service professionals are the primary installers.

Key Features

• Microprocessor-based control with on-off primary burner management
• Supports gas, oil, coal, and combination fuel single-burner applications
• Intermittent pilot ignition with prepurge sequence
• Selectable interlocks for site-specific safety configuration
• Shutter drive output and valve proving feature for enhanced safety
• Blinking LED fault annunciation for fast field diagnostics

Compatibility

Designed as an OEM-style replacement or upgrade control for industrial and commercial single-burner systems requiring on-off primary control with prepurge and intermittent pilot supervision.

Installation Notes

Installation should be performed by a licensed burner technician or qualified industrial HVAC professional familiar with combustion controls and applicable codes including NFPA 85 and NFPA 86. Shut off all fuel supplies and de-energize the system fully before removing the existing control or making any wiring connections. Verify interlock selections match the burner system's safety requirements before commissioning. Do not energize the control without confirming all interlocks, valve proving circuits, and flame supervision components are properly connected and functional.
