Laars Heating Systems RXD7198 Control Board
The Laars Heating Systems RXD7198 Control Board is a critical OEM replacement part engineered for precise thermal management and system logic within high-efficiency hydronic systems. Specifically designed for the Laars NeoTherm NTH150-210 series, this HVAC control board integrates advanced microprocessor logic to regulate combustion air flow, ignition sequences, and variable firing rates. For contractors performing boiler control board replacement, the RXD7198 provides a plug-and-play interface that minimizes diagnostic overhead by utilizing an onboard digital display for real-time error code reporting and system status monitoring. By maintaining tight tolerances on fuel-to-air ratios, this module ensures the Laars heating system operates at peak efficiency while protecting sensitive components from operational faults. Its ruggedized circuitry is built to withstand the thermal cycling typical of commercial and residential gas-fired boiler applications, providing consistent modulation and reliable communication with secondary sensors and pumps.
Key Benefits for Technicians:
- Precise Modulation: Regulates the combustion blower and gas valve to adjust firing rates based on real-time demand, maximizing fuel efficiency.
- Streamlined Troubleshooting: Features an integrated digital interface that displays diagnostic codes, allowing for rapid identification of system lockouts or sensor failures.
- Verified Compatibility: Direct OEM replacement for Laars NeoTherm NTH150 and NTH210 models, ensuring correct wiring harness alignment and logic setpoints.
- Enhanced Operational Safety: Continuously monitors flame rectification, vent temperature limits, and pressure switches to prevent unsafe operating conditions.
- Direct-Fit Integration: Designed with standard terminal blocks for a secure, professional installation that restores factory-spec performance.
Common Questions:
Which boiler models are compatible with the RXD7198 board?
This specific control board is engineered for Laars NeoTherm models NTH150 and NTH210. Always verify the part number on your existing module against the unit’s rating plate before installation.
Does this board require proprietary software for setup?
No, the RXD7198 is designed for manual configuration through its intuitive onboard interface, allowing field technicians to adjust parameters and setpoints directly on the unit.
How can I diagnose a failure versus a sensor issue?
Utilize the onboard diagnostic display to check for specific error codes. If the display remains blank despite a confirmed 24VAC power supply from the transformer, the board itself has likely failed.
