Product Overview
The Telaire 8000 Ventostat series offers wall-mount CO2, humidity, and temperature transmitters designed for controlled ventilation in commercial HVAC applications. These devices help maintain indoor air quality, optimize energy efficiency by preventing over-ventilation, and are ideal for spaces with fluctuating occupancy. Featuring patented sensor technology and self-calibration systems, the Ventostat 8000 series ensures high accuracy and minimizes maintenance. The two-piece design allows for easy installation and replacement without rewiring. Available in various configurations including models with displays and BACnet output, these transmitters are suitable for controlling specific areas like conference rooms, classrooms, and meeting halls.
