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 losses from over-ventilation, and are ideal for spaces with fluctuating occupancy like conference rooms, classrooms, and meeting halls. Featuring patented NDIR sensing technology and ABC Logic self-calibration, they provide high accuracy 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, they offer dual simultaneous analog outputs (V & mA) for CO2.
