Product Overview
The Telaire 8000 Ventostat series offers wall-mount CO2, humidity, and temperature transmitters designed for controlled ventilation in commercial HVAC applications. These transmitters help maintain indoor air quality, optimize energy efficiency by preventing over-ventilation, and ensure a healthy, productive environment. Featuring advanced sensing technology like patented Absorption Infrared Gas sensing and ABC Logic self-calibration, they provide high accuracy and minimize maintenance. The two-piece design facilitates easy installation and replacement without rewiring. Available in various configurations, including models with displays and BACnet output, the Ventostat 8000 series is suitable for controlling specific areas such as conference rooms, classrooms, and meeting halls.
