Aaon ASM01836 E-Bus Outdoor Air Temperature and Humidity Sensor with Cable

The Aaon ASM01836 is an E-Bus horizontal outdoor air temperature and relative humidity sensor designed for integration with AAON HVAC unit controllers. This dual-function sensor monitors both outdoor air temperature and humidity levels to enable advanced economizer control strategies and optimize system performance.

Key Features:

• Digital capacitive sensing element for accurate temperature and humidity measurement
• Temperature sensing range: -40°F to 185°F with ±0.8°F accuracy
• Relative humidity sensing range: 0-100% with ±3% accuracy
• Weatherproof plastic enclosure for outdoor installation durability
• E-Bus digital communication protocol for seamless controller integration
• Includes attached 3-foot pigtail with female E-Bus connector plus 25-foot standard E-Bus cable

This sensor connects directly to VCCX2, VCCX-IP, VCCX-454, VCB-X, and other compatible AAON unit controllers via the E-Bus modular cable system. It enables wetbulb and dewpoint economizer control strategies, making it essential for applications requiring precise outdoor air monitoring. The sensor is particularly useful in Make-Up Air (MUA) and Dedicated Outdoor Air System (DOAS) applications where dehumidification control based on outdoor dewpoint is critical for maintaining optimal indoor air quality and energy efficiency.
