Velocity Boiler Works (Crown) 240022 Outside Temp Sensor NTC – AH

Description

The Velocity Boiler Works (Crown) 240022 Outside Temperature Sensor (NTC – AH) is a precision outdoor reset sensor engineered for use with compatible Crown and Velocity Boiler Works hydronic heating systems. By continuously monitoring outdoor ambient temperatures, this NTC (Negative Temperature Coefficient) sensor enables the boiler control to modulate supply water temperature in response to changing weather conditions — delivering optimal comfort while maximizing fuel efficiency.

Key Features

• NTC (Negative Temperature Coefficient) thermistor design for accurate, responsive temperature sensing
• Designed for outdoor ambient temperature monitoring in hydronic boiler systems
• Enables outdoor reset control to optimize boiler water temperature relative to outside conditions
• Direct OEM replacement for compatible Velocity Boiler Works and Crown boiler controls
• Durable construction suitable for exterior mounting in varying weather conditions
• Helps reduce fuel consumption and improve system efficiency through intelligent load matching

Application

This sensor is intended for installation on an exterior wall or surface where it can accurately read outdoor air temperature without direct exposure to sunlight, precipitation, or other heat sources. Proper placement ensures the boiler control receives reliable data for outdoor reset operation, extending equipment life and reducing operating costs.

Why Outdoor Reset Sensing Matters

Outdoor reset control is one of the most effective strategies for improving hydronic heating efficiency. By lowering supply water temperature during mild weather, the boiler operates at lower stack temperatures, reduces cycling, and minimizes standby losses. The 240022 sensor is the critical input that makes this intelligent control strategy possible.
