Description

The Veris GWNVXXW is a wall-mounted modular gas sensor platform designed for building automation and HVAC systems. It serves as a housing base that converts gas readings into field-selectable, analog, or relay signals (0 to 5 Vdc, 0 to 10 Vdc, or 4 to 20 mA) to communicate with Direct Digital Control (DDC) systems or directly control fans.

 

Key Features

• Modular Design: The base accepts interchangeable Veris AG Series gas sensors (sold separately), allowing you to detect gases like carbon monoxide (CO) or nitrogen dioxide (NO₂) without requiring entirely new hardware.
• Easy Maintenance: When a sensor reaches the end of its life, the base remains wired to the wall. You simply open the white (W) housing to swap out the modular sensor, eliminating costly re-installations.
• Visual Diagnostics: Features three colored LEDs (red, yellow, and green) for quick, at-a-glance status viewing.
• Stable Operation: Microprocessor-controlled for excellent stability, requiring no field calibration.
