Description
Overview: Microprocessor-based integrated burner control for automatically fired gas, oil, coal or combination fuel single burner applications. Provides safety, functional capability and features beyond conventional controls.
Features:
- Functions include automatic burner sequencing, flame supervision, system status indication, system or self-diagnostics and trouble shooting.
- Access for external electrical voltage checks.
- Application flexibility and communication interface capability.
- Five LEDs provide sequence information.
- Five function Run/Test Switch.
- Interchangeable plug-in flame amplifiers.
- Local or remote annunciation of operation and fault information (optional).
- Nonvolatile memory retains history files and lockout status after loss of power.
- Compatible with existing Honeywell flame detectors.
- Includes Keyboard Display Module.
The Honeywell RM7838B1013 is a manual-start, microprocessor-based programming control designed for industrial semi-automatically fired single burner applications. Part of Honeywell's 7800 Series, it supports gas, oil, coal, or combination fuel burners and includes the S7800A Keyboard Display Module. This unit is discontinued but new old-stock units remain available — making this listing especially valuable for maintenance and replacement applications.
This control provides a higher level of safety, functional capability, and diagnostics than conventional burner controls, with features specifically designed for industrial combustion environments requiring proven purge, low/high fire (LHL-LF & HF) sequencing, and manual operator start.
Key Features
- Manual start operation — requires operator initiation, suited for semi-automatic industrial burner applications
- Proven prepurge — delays fuel admission until pilot flame is verified, with LHL-LF & HF proven purge sequencing
- Interrupted pilot with lockout interlocks — pilot established, then shut off once main flame is proven; includes preignition and early spark termination
- Selectable pilot flame establishing period — 4-second or 10-second pilot FEP; 10-second main flame or intermittent
- Five LEDs — provide real-time sequence status indication
- Five-function Run/Test switch — for commissioning and troubleshooting
- Interchangeable plug-in flame amplifier — supports UV, IR, and rectification flame detection
- Nonvolatile memory — retains history files and lockout status through power loss
- Included S7800A Keyboard Display Module (KDM) — 4-line LCD for on-board diagnostics, status, and fault history
- Compatible with existing Honeywell flame detectors
- Optional communication interface — supports Data ControlBus™ and PC interface add-ons

Common Applications
The RM7838B1013 is used in industrial boilers, process burners, furnaces, kilns, and other heavy combustion equipment requiring manual-start operation with proven purge and high/low fire capability. It is particularly suited for applications where an operator must initiate each burner cycle, such as industrial ovens, drying systems, and multi-fuel process heating equipment.
Important Notes
- This product is discontinued by Honeywell — units available are new old-stock; no factory reorders available
- Not weather-tight — must be protected by an approved enclosure when installed outdoors
- A separate primary control and wiring subbase are required for a complete system
- Ensure all manual fuel shutoff valves are closed before installation or static checkout
