Honeywell RM7800 / RM7840 to Fireye BurnerLogiX Conversion Guide
Replacing a Honeywell RM7800 or RM7840 flame safeguard doesn’t have to mean staying with Honeywell. Fireye’s BurnerLogiX platform is a direct conversion target — and with the 60-BLX-HON-VP and 60-BLX-HON-NVP wiring base adapters, the changeover uses your existing Q7800 wiring base, so there’s no panel rewiring for most installations.
This guide covers the three things you need to make the switch: which BurnerLogiX chassis, programmer, and display replace your RM7800L, RM7800M, or RM7840L; which adapter matches your application (VP for valve proving, NVP without); and the terminal-by-terminal wiring notes from Fireye’s conversion documentation — including the early-spark-termination and indication-switch details that trip up first-time conversions.
Reasons customers make this conversion: BurnerLogiX availability when RM7800-series lead times stretch, cost, valve-proving and low-gas-pressure support, and a preference for made-in-USA controls. Note the height check before committing: a BurnerLogiX chassis on the adapter stack measures about 7″ — fine for a typical 8–9″ panel, but verify yours.

1. Replacing Honeywell RM7800/RM7840 Controls
When upgrading from a Honeywell RM7800 or RM7840 series flame safeguard, the Fireye BurnerLogiX offers a modern, feature-rich alternative. The integration is simplified through the use of dedicated wiring base adapters, which allow the new BurnerLogiX chassis to mount directly onto the existing Honeywell Q7800 subbase. This approach minimizes downtime and eliminates the need for extensive panel rewiring.
Key considerations for this conversion include verifying the exact model of the existing Honeywell control to ensure the correct BurnerLogiX chassis, programmer module, and display are selected. Additionally, attention must be paid to the specific requirements of the application, such as valve proving and precise purge timings, to guarantee a safe and compliant installation.

| Part to be replaced | Recommended replacement | Notes/required accessories |
|---|---|---|
| Honeywell RM7800L1012 | Fireye YB110UV / YP100 / BLV512 | Use existing Q7800 base. Verify UV scanner compatibility (e.g., UV1A). |
| Honeywell RM7800M1010 | Fireye YB110IR / YP300 / BLV512 | Infrared configuration. Uses existing Q7800 base via adapter. |
| Honeywell RM7840L1018 | Fireye YB110UV / YP138 / BLV512 | Matches 30-second purge timing logic and non-recycled limit circuit. |
| Honeywell RM7840G1022 | Fireye YB110UV / YP102 / BLV512 | Standard UV configuration; verify display mounting cutout on panel door. |
| Honeywell RM7840E1016 | Fireye YB110FR / YP100 / BLV512 | Check flame rod amp requirements before ordering. |
| Honeywell RM7845A1009 | Fireye YB110UV / YP138 / BLV512 | Confirm 30-second vs 2-second purge timing. |
3. Wiring Base Adapter Selection (Ref: 133-800)
| Part to be replaced | Recommended replacement | Notes/required accessories |
|---|---|---|
| Honeywell Q7800 (with Valve Proving or LGP) | Fireye 60-BLX-HON-VP | For systems utilizing integrated Valve Proving Logic (VPS) or Low Gas Pressure functionality. Includes 5-pin green connector for S1/S2 scanner wiring. |
| Honeywell Q7800 (Standard, no Valve Proving) | Fireye 60-BLX-HON-NVP | For standard applications. Mounts directly to existing Q7800 subbase with zero panel rewiring. |
4. Conversion Wiring Notes (Ref: 133-800)
| Part to be replaced | Recommended replacement | Notes/required accessories |
|---|---|---|
| Wiring Note 1: Early-Spark Termination | Ignition Transformer (Terminal 10) | Verify Terminal 10 ignition transformer wiring against the Fireye YP programmer early-spark termination (PTFI) timing requirements. |
| Wiring Note 2: Indication Switch Circuit | Auxiliary Contacts | Ensure proper auxiliary switch contact closure mapping prior to sequence initialization. A wiring jumper may be required depending on original RM7800 auxiliary setup. |
| Wiring Note 3: Enclosure Stack Height | Panel Depth Check | Combined adapter + BurnerLogiX chassis height is approximately 7 inches. Confirm panel depth is at least 8–9 inches to prevent door clearance collision. |
