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, prevent energy losses from over-ventilation, and support demand-controlled ventilation strategies, particularly in buildings with fluctuating occupancy. Featuring patented sensing technologies like ABC Logic for self-calibration and a lifetime CO2 calibration guarantee on select models, these units ensure accuracy and minimize maintenance. Their two-piece design facilitates easy installation and replacement without rewiring, making them ideal for controlling specific areas such as conference rooms, classrooms, and meeting halls.
