Laars Heating Systems 2400-441 Module
The Laars 2400-441 Ignition Module is a critical 24V intermittent pilot ignition control engineered for reliable sequence management in high-efficiency Laars heating systems. This heavy-duty integrated furnace control features a 7-second pre-purge (PP) cycle and an integrated pilot (IP) protocol to ensure safe combustion startup. Designed with a 9-second trial for ignition (TFI) windows, the 2400-441 provides precise flame rectification and monitoring, preventing fuel accumulation in the chamber during failed cycles. This specific module is an essential OEM replacement part for technicians servicing Laars Pennant, Mascot, and Rheos boiler series. Its solid-state circuitry is built to withstand the thermal stress of continuous commercial cycles, providing consistent spark-to-pilot ignition and main burner control. When diagnosing lockout issues or erratic flame signals, this HVAC control board offers the industrial-grade reliability required to restore system uptime and maintain strict safety parameters within the mechanical room.
Key Benefits for Technicians- Precise Timing: Features a factory-set 7sPP/IP/PP sequence for consistent scavenging and ignition.
- Enhanced Safety: Includes a 9sTFI (Trial For Ignition) to protect against delayed ignition or gas buildup.
- Direct Fit Compatibility: Genuine Laars replacement part ensures mounting holes and terminal connections align perfectly with existing wiring harnesses.
- Intermittent Pilot Control: Optimizes fuel efficiency by only utilizing the pilot during the heating call, reducing standby losses.
- Robust Diagnostic Support: Designed to interface with standard multi-meter probes for rapid troubleshooting of flame sense current and voltage drops.
Does this module support continuous retry if the flame signal is lost?
The 2400-441 is programmed for specific lockout sequences depending on the boiler's firmware; typically, if the 9-second TFI period is exceeded without a flame sense signal, the module will initiate a safety lockout to ensure site safety.
Can I use this to replace older Honeywell or Fenwal modules in Laars units?
While many 24V ignition modules share similar footprints, this Laars 2400-441 is calibrated for specific pre-purge timings required by the blower assemblies in Pennant and similar series. Always verify the part number against the unit’s data plate.
What is the primary cause of failure for these ignition controls?
Most failures stem from poor grounding, moisture exposure, or excessive vibration. Ensure the flame sensor is clean and the ground wire has a low-resistance path to the chassis to prevent nuisance lockouts.
