Laars Heating Systems RXD7207 Control Module
The Laars Heating Systems RXD7207 Control Module is a critical OEM replacement component designed for high-performance 600/750 NT boiler models. Engineered for the demanding environments of commercial and industrial hydronic heating, this Laars boiler control board (formerly identified with Honeywell Sola technology like the R7910A1118) manages the complete sequence of operation, including direct spark ignition, flame rectification, and combustion blower modulation. By regulating the air-to-fuel ratio and monitoring safety limits, the RXD7207 control module ensures optimal thermal efficiency and prevents intermittent lockouts common in aging Laars 600/750 NT mods.
This genuine Laars replacement part features a plug-and-play architecture with keyed connectors to eliminate wiring errors during field installation. It includes advanced onboard diagnostics, allowing technicians to access real-time status through the user interface and review comprehensive boiler error code history for rapid troubleshooting. Whether you are addressing a "no-flame" condition or calibrating the high-limit setpoints, the RXD7207 provides the precise logic required to maintain the system integrity of Laars NeoTherm series units. For pros, this module is the standard for restoring reliable temperature control and fail-safe operation to 750 MBH modulation units.
Key Benefits:
- Precise Modulation Control: Manages variable firing rates for Laars 600/750 NT boiler models to maximize energy savings.
- Enhanced Safety Monitoring: Continuous oversight of flame signals, gas valve voltage, and airflow switches to prevent hazardous conditions.
- OEM Compatibility: Facilitates an exact fit and immediate communication with existing Laars Heating Systems sensors and displays.
- Technical Diagnostics: Direct access to lockout history and alert detail helps isolate faults in the ignition or combustion cycle.
- Durable Construction: Built to withstand the thermal cycling and humidity levels found in commercial boiler rooms.
Common Questions:
Will this module fix an E11 (Ignition Failed) or E10 (Flame Extinguished) error?
While the RXD7207 control module processes the ignition sequence, these errors often relate to the ignitor, gas valve, or burner plate. However, if the board fails to send 24-28 VAC to the gas valve or loses the flame rectification signal despite a healthy sensor, the RXD7207 is likely the component at fault.
Is this a direct replacement for Honeywell Sola boards?
Yes, the RXD7207 is the official Laars replacement for several obsolete Honeywell-based control units used in the 600 and 750 NT modulation series.
Does this board require programming after installation?
While the module is factory-loaded with standard logic, technicians must verify and adjust DIP switch settings and installer parameters (such as CH/DHW setpoints and outdoor reset curves) according to the specific system manual.
