Applications

Controlled Ventilation

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 sensors 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 sensors.

Wall mount sensors are used to control a specific area such as a conference room, classroom, meeting hall, etc. The Telaire 8000 Ventostat series are easy to install and have a clean, modern look that suits most indoor environments.

 

Ventostat UIP Software T2090

The Ventostat UIP software allows you modify the standard settings on the T8100, T8200 and T8300 series products.

The T2090 UIP software kit is supplied with a USB to Ventostat cable and software CD. The USB cable supplies power to the Ventostat negating the need for a separate power supply.
The software features:

  • Altitude adjustment for maximum accuracy performance
  • Analog output adjustment
  • Single point and span gas calibration
  • Turn on and off ABC logic
  • Change temperature display units
  • Graphing and logging of Co2, temp and %RH (H Versions only)
