Laars Heating Systems RE2319900 Sensor
The Laars Heating Systems RE2319900 Sensor is a precision-engineered Outlet Temp Sensor Duplex designed for critical monitoring in high-efficiency hydronic systems. Built for the technical demands of Laars MagnaTherm and NeoTherm boilers, this duplex sensor features dual thermistor elements to provide redundant, high-accuracy fluid temperature data to the control board. This 1/4 NPT sensor fitting allows for a threaded, leak-proof installation directly into the heat exchanger outlet, ensuring the system maintains correct modulation and high-limit safety thresholds without the lag often seen in surface-mount alternatives.
For service technicians, the RE2319900 is the direct OEM replacement mandated for resolving frequent Laars boiler error codes related to temperature stratification or sensor mismatched readings. Incorporating this replacement water temperature sensor ensures the boiler operates at peak thermal efficiency by allowing the integrated logic to adjust firing rates based on real-time outlet conditions. Its robust construction is specifically rated for the high-cycle thermal stress found in commercial and residential Laars heating systems, preventing the drift common in generic aftermarket sensors.
Key Benefits for the Contractor:
- Direct OEM Compatibility: Engineered specifically for NeoTherm and MagnaTherm series, ensuring nested fitment and accurate resistance scaling.
- Duplex Redundancy: Features a dual-element design for simultaneous measurement, providing the controller with a secondary reference for safety validation.
- Precision Threading: Uses a standard 1/4 NPT fitting for a secure, airtight seal within the flow path.
- Optimized System Efficiency: Eliminates short-cycling and improper modulation by delivering rapid-response temperature feedback.
Common Questions:
Does this sensor require a specific orientation during installation?
While the 1/4 NPT threads allow for standard installation, ensure the probe is fully submerged in the flow stream and use a high-quality thread sealant approved for hydronic applications to prevent leaks under system pressure.
Can I use this to replace a single-element sensor on older Laars models?
The RE2319900 is a duplex (dual) sensor. It is designed for newer control boards that monitor two internal thermistors. Always verify your specific control board inputs before replacing a single-element probe with this duplex model.
What are the symptoms of a failing outlet temperature sensor?
Technicians typically see intermittent lockout codes, erratic temperature displays on the HMI, or the boiler failing to reach setpoint due to false high-limit readings. Resistance testing across the thermistor leads is recommended to confirm failure.
