Laars Heating Systems E2347400 Sensor
The Laars E2347400 Outdoor Temperature Sensor is a critical NTC (Negative Temperature Coefficient) thermistor designed for high-precision environmental monitoring in residential and commercial hydronic heating systems. As a genuine OEM replacement part, this 10k ohm sensor facilitates outdoor reset control, allowing the boiler to automatically adjust its water temperature based on ambient conditions. This weatherproof outdoor sensor delivers real-time resistance feedback to the control board, preventing short-cycling and optimizing fuel delivery for maximum combustion efficiency.
Built to withstand harsh thermal cycling, the E2347400 acts as the primary data point for hydronic heating equipment diagnostics and load compensation. The durable housing protects sensitive thermistor technology from moisture and UV exposure, ensuring consistent temperature measurement for Laars boiler parts across a wide operating range. Integrating this sensor is essential for contractors aiming to reduce energy costs and maintain stable indoor climates through advanced boiler ambient temperature sensing.
Key Benefits
- Precise Outdoor Reset: Enables the heating system to modulate output based on external air temperature, significantly increasing energy efficiency.
- Direct OEM Compatibility: Engineered for a seamless fit with Laars Heating Systems models including the Minitherm JVH and JVS series.
- Rugged Weatherproof Design: Enclosed in a robust housing to survive extreme outdoor environments without signal drift.
- Improved System Longevity: Helps prevent unnecessary boiler wear by ensuring the system only operates at the required thermal load.
- Technical Accuracy: Utilizes NTC thermistor technology for rapid response times and reliable temperature feedback.
Common Questions
Which Laars models are compatible with the E2347400 sensor?
This sensor is used across various Laars Heating Systems, most notably compatible with the JVH075, JVS100, and Minitherm series boilers. Always verify the specific resistance requirements found in your unit's technical manual.
How does this sensor improve boiler performance?
By providing outdoor temperature measurement, the E2347400 allows the system to implement an outdoor reset curve. This ensures the hydronic heating equipment runs only as hot as necessary, reducing standby losses and fuel consumption.
Can I test the E2347400 sensor with a multimeter?
Yes, as an NTC sensor, you can measure its resistance. For a 10k sensor, at 77°F (25°C), you should see approximately 10,000 ohms. Resistance will increase as the outdoor temperature drops.
