Ventilation is an important part of maintaining a comfortable, healthy, productive environment for people. Improper ventilation can have a negative impact on occupant health and performance, increase the risk from litigation, and/or waste energy. Demand-controlled ventilation using CO2 Transmitters prevents energy losses from over-ventilation while maintaining indoor air quality. The most energy savings potential is in buildings where occupancy fluctuates during a 24-hour period. Numerous organizations now require and/or recommend CO2-based ventilation control in different commercial HVAC applications. Some utility companies also offer rebates to building owners for installing CO2 Transmitters.

Wall mount Transmitters are used to control a specific area such as a conference room, classroom, meeting hall, etc. The Telaire T8100-HD-GN Ventostat series are easy to install and have a clean, modern look that suits most indoor environments.

GE Telaire Ventostat T8100-HD-GN duct mount Transmitter uses a single channel Transmitter using Telaire patented ABC Logic for lifetime calibration. Single-channel Transmitters are used in spaces where there is not full-time occupation (most applications).

CO2 ABC Logic Self Calibration

Ventostat T8100-HD-GN CO2 duct mount Transmitter's single channel Transmitters employ the patented ABC (Automatic Background Calibration) Logic self-calibration system. ABC Logic virtually eliminates the need for manual calibration in applications where the indoor CO2 level drops to outside levels during unoccupied periods (e.g. during evening hours). ABC Logic is a special software routine in the Transmitter that remembers the background readings for 14 consecutive evenings, calculates if there is a Transmitter drift, and then corrects for it.

With ABC Logic enabled, the Transmitter will typically reach its operational accuracy after 25 hours of continuous operation at a condition that is exposed to ambient reference levels. Transmitters will maintain accuracy specifications with ABC Logic enabled, given that it is at least three times in 14 days exposed to the reference value and this reference value is the lowest concentration to which the Transmitter is exposed.

Calibration Interval

For GE Telaire T8100-HD-GN series, no calibration is required due to ABC Logic. If a Telaire 8000 series single channel Transmitter drifts out of calibration range, it can be sent back for a free factory calibration.
