Description
The Laars Heating Systems E2347400 is a genuine OEM NTC (Negative Temperature Coefficient) outdoor temperature sensor designed for use with compatible Laars boilers and heating systems. This sensor plays a critical role in outdoor reset control strategies, continuously monitoring ambient outdoor temperatures and feeding that data to the boiler control — enabling the system to modulate water temperature based on actual heating demand. The result is improved comfort, reduced fuel consumption, and extended equipment life.
Key Features
- Genuine Laars Heating Systems OEM replacement part
- NTC thermistor-type sensor for accurate, responsive temperature measurement

Application
This outdoor temperature sensor is intended for installation on an exterior wall or other outdoor location where it can accurately measure ambient air temperature. It communicates with the boiler’s control board to enable weather-responsive heating, reducing boiler water temperature during mild weather and increasing it during cold snaps — optimizing efficiency across all conditions.
Why Choose a Genuine OEM Sensor?
Using a genuine Laars replacement sensor ensures compatibility with your system’s control board and maintains the accuracy of your outdoor reset curve. Aftermarket sensors may have different resistance characteristics that can cause incorrect temperature readings, leading to comfort issues or reduced efficiency. Trust the OEM part for reliable, long-term performance.
