aSense Ventostat 2,000ppm CO2 + RH/T

• LEED Projects & Credits
• Green building design
• Green building certification
• CO2-Controlled Fan or Alarm

The aSense is an all-digital, low-cost CO2 and temperature transmitter for installation in a building’s climate zone. It measures both carbon dioxide concentration and temperature in real-time, and returns the values to the HVAC system.

The aSense is a key component in green building projects and is designed to maximize LEED credits for both LEED design retrofits and new LEED buildings. Studies show that demand-controlled HVAC systems using CO2 can save up to 50% of energy costs as well as improving comfort for the occupants.

For installations that need to drive a fan, alarm, horn, flasher, etc, the aSense -RL includes a normally open relay programmed to close at 1,000ppm.

Variations

• SE-0115: 0-2,000ppm CO2, temp, 4-20mA or 0-10VDC outputs
