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, prevent energy waste from over-ventilation, and contribute to occupant health and productivity. Featuring patented NDIR gas sensing technology and ABC Logic self-calibration for most applications, they provide accurate and reliable measurements. 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 like conference rooms, classrooms, and meeting halls.
