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 support demand-controlled ventilation strategies. Featuring patented sensor technology and self-calibration systems, they provide accurate measurements with minimal maintenance. The two-piece design allows for 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.
