Description
The Laars Heating Systems RE2310500 is an outdoor temperature sensor engineered specifically for use with Laars NT, LMC, and LMH series boilers. Designed to support outdoor reset functionality, this sensor continuously monitors ambient outdoor temperatures and feeds that data to the boiler control system — enabling the boiler to modulate water temperature based on actual heating demand. The result is improved energy efficiency, greater comfort, and reduced fuel consumption across varying seasonal conditions.

Why Outdoor Reset Matters
Outdoor reset control is one of the most effective strategies for improving hydronic heating system efficiency. By using real-time outdoor temperature data, the boiler control can lower supply water temperatures during mild weather and raise them only when outdoor conditions demand it. This reduces short-cycling, lowers fuel costs, and extends equipment life — making the RE2310500 sensor a critical component for any properly commissioned Laars boiler installation.
Installation & Application
The RE2310500 is a genuine Laars OEM replacement part, ensuring seamless compatibility and straightforward installation. It is intended for outdoor mounting in a location that accurately reflects ambient air temperature, away from direct sunlight, exhaust vents, or other heat sources. Always refer to the Laars boiler installation and service manual for specific wiring and mounting instructions.
