Laars Heating Systems 2400-552 Sensor

Laars Heating Systems 2400-552 Sensor

The Laars Heating Systems 2400-552 Sensor is a precision-engineered Teledyne boiler control sensor designed for accurate thermal monitoring in high-demand hydronic applications. As an essential component for Laars boiler parts maintenance, this NTC thermistor-based sensor provides the real-time data necessary for the integrated control system to regulate ignition, timing, and blower operation. With a high sensitivity rating—typically around 11,900 Ohms at 70°F—it ensures the HVAC control board can maintain precise setpoints between 100°F and 183°F. This replacement boiler sensor is frequently utilized in SMB, SMW, EBP, and ED series units to monitor boiler tank temperature or return flow, preventing thermal overshoot and maximizing fuel efficiency across multiple firing stages. Its robust construction is built for the thermal cycling and vibration common in commercial mechanical rooms, making it a reliable choice for field repairs.

Key Benefits for Technicians:
  • Optimized Compatibility: Designed specifically for Laars and Teledyne control circuits to ensure seamless communication with the boiler control module.
  • System Protection: Delivers high-accuracy data to the ECO (Energy Cut-Off) circuit to prevent overheating and potential equipment damage.
  • Simplified Installation: Features a standard lead length and connector for rapid field replacement in existing sensor wells.
  • Increased Efficiency: Facilitates tight modulation and outdoor reset ratios by providing stable resistance readings to the sequencing control.
Common Questions:

What are the symptoms of a failing Laars 2400-552 sensor?
Common indicators include erratic temperature displays on the control board, "Sensor Open" or "Sensor Short" error codes, and the boiler failing to fire or short-cycling due to inaccurate thermal feedback.

Does this sensor require a specific immersion well?
While often installed in a pre-existing well, it is vital to ensure the sensor makes direct contact with the well bottom and use thermal conductive paste to maintain accuracy and response time.

Are there specific resistance values to check during troubleshooting?
Yes, technicians should verify the resistance against a standard 10k or 12k curve (nominal 11.9k Ohms at 70°F) using a calibrated multimeter to confirm the part is within manufacturer specifications before installation.
