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, prevent energy waste from over-ventilation, and are ideal for areas with fluctuating occupancy. Featuring a patented Absorption Infrared Gas sensing engine and ABC Logic self-calibration system, they provide high accuracy and eliminate the need for manual calibration in most applications, backed by a lifetime CO2 calibration guarantee for T8100 and T8300 models. The two-piece design allows for easy replacement without rewiring, and modern enclosures with customizable branding are available. Suitable for controlling specific areas like conference rooms, classrooms, and meeting halls.
