Carrier NSA-ASENSE-D-LCD-REL Owner's Manual Installation And Operation

#NSA-ASENSE-D-LCD-REL, NSA-ASENSE-D-REL – 11/14/2019
Overview
The ASENSE Duct series with IP65 Rated Enclosure monitors the carbon dioxide (CO2) levels
in industrial, commercial, school, and office type environments. The concentration of CO2 is a
strong indication of the overall indoor air quality. The ASENSE Series is based on a single beam
non-dispersive infrared technology and is a cost-optimized solution for the climate control of
buildings and other processes. In addition, ABC software eliminates the need for manual
calibration. The ASENSE Series measures the CO2 concentration in the ambient air up to 2,000
ppm and converts the data into an analog output. This data can be used in conjunction with a
Building Automation or Demand Control Ventilation System to create a healthier indoor climate.
This series features an analog temperature output (32 to 122°F) and come with combined
output options of 0-10 VDC and 0 to 20 mA (4 to 20 mA and 2-10 VDC are field selectable via
an onboard jumper) or 0-5 VDC for "-5" versions. A relay option is available for this series as
well. The UIP5 software and programming cable offer a configuration/test utility and provide
access to the main features of the ASENSE series.
Applications: Commercial Office Buildings, Hospitals & Schools
