Product Overview
The Telaire Wall Mount CO2, Humidity, and Temperature Transmitters, part of the Ventostat 8000 series, are designed for controlled ventilation in buildings. They help maintain indoor air quality, occupant health, and productivity while preventing energy waste from over-ventilation. These transmitters are ideal for demand-controlled ventilation strategies, particularly in buildings with fluctuating occupancy. They are suitable for controlling specific areas like conference rooms, classrooms, and meeting halls. The two-piece design allows for easy replacement without rewiring, and modern enclosures can be customized with branding. Available in various configurations, including models with dual analog outputs (V & mA) and BACnet output versions, these sensors are factory calibrated and feature a lifetime CO2 calibration guarantee when using ABC Logic.
