Product Overview
The Telaire 8000 Ventostat series offers reliable wall-mount CO2, humidity, and temperature transmitters designed for controlled ventilation in commercial HVAC applications. These transmitters help maintain indoor air quality, prevent energy losses from over-ventilation, and ensure a healthy, productive environment. Featuring patented sensing technologies like Absorption Infrared Gas sensing and ABC Logic self-calibration, they provide high accuracy and minimize maintenance needs. The two-piece design allows for easy installation and replacement without rewiring. Available in various configurations, including models with BACnet output, dual analog outputs, and optional displays, the Ventostat 8000 series is suitable for areas with fluctuating occupancy, such as conference rooms, classrooms, and meeting halls.
