Commercial HVAC ventilation control using Amphenol T8200-GN CO2 humidity and temperature transmitter
Product Overview
The Telaire 8000 Ventostat series offers reliable wall-mount CO2, humidity, and temperature transmitters designed for controlled ventilation in commercial HVAC applications. These transmitters help maintain optimal indoor air quality, enhance occupant health and productivity, and prevent energy waste from over-ventilation. Featuring patented sensing technology and self-calibration systems, they minimize maintenance requirements. The two-piece design facilitates 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.
