Product Overview
Telaire Ventostat 8000 series wall mount transmitters are designed for monitoring CO2, humidity, and temperature in occupied building HVAC applications. These devices are crucial for demand-controlled ventilation, preventing energy waste from over-ventilation while maintaining indoor air quality. They are ideal for controlling specific areas like conference rooms, classrooms, and meeting halls. The series features a patented Absorption Infrared Gas sensing engine for high accuracy and a patented ABC Logic self-calibration system that eliminates the need for manual calibration in most applications, offering a lifetime CO2 calibration guarantee for T8100 and T8300 models. The two-piece design allows for easy unit replacement without rewiring, and a modern enclosure with optional customized branding is available.
