Product Overview
Telaire Ventostat 8000 series wall mount transmitters are designed for monitoring CO2, humidity, and temperature in building HVAC applications. These devices are crucial for demand-controlled ventilation, preventing energy waste from over-ventilation while maintaining optimal indoor air quality. They are ideal for controlling specific areas such as conference rooms, classrooms, and meeting halls. Key features include patented Absorption Infrared Gas sensing engines, ABC Logic self-calibration for most applications, and a two-piece design for easy replacement without rewiring. Available in various configurations, including models with displays and BACnet output, these transmitters offer dual simultaneous analog outputs (V & mA) for CO2 and include a temperature sensor on all models.
