Telaire T8002-ACD Series

Ventostat T8002-ACD

Programmable Wall Mount CO2 Transmitters with Relay Output

The Telaire Ventostat T8002-ACD and T8002-ACD-2K are wall mounted sensors that provide CO2 control even when a building management system is not in place, using the relay feature. These two units are designed to be used in specific areas such as indoor growing areas, conference rooms, classrooms, meeting halls, etc. Even though the sensors are designed for wall mount configurations, some sensors can also be configured for "in-duct" mount. For in-duct, the sensor is mounted inside the duct to control an entire air-handling zone.

All wall mount sensors are compatible with accessory enclosures. The Ventostat controller offers a SPDT relay (normally open or closed) and can be custom programmed to a specific measurement and output range using the UIP software interface (T2072) or on-board keypad (display units).
