Carrier NSA-HH/CO2-R2-CP-C Additional Instructions For Installation And Operation

#NSA-HH/CO2-R2-CP-C, NSA-HH/CO2-R2O-CP-C, NSA-HH/CO2-R2SO-CP-C – 11/14/2019

Overview

The Carrier Carbon Dioxide Room Series Sensor with Temperature, Setpoint, and Override monitors the
carbon dioxide (CO2) levels in commercial, school, and office-type environments. The concentration of
CO2 is a strong indication of the overall indoor air quality. The NSA-HH/CO2-R2 Series is based on a
single beam, non-dispersive infrared technology and is a cost-efficient solution for measuring carbon
dioxide levels for building climate control. In addition, ABC software eliminates the need for manual
calibration. Carbon Dioxide concentration is measured up to 2,000 ppm and is converted into
proportional analog outputs. The factory default output is 4-20 mA, whereas 0-5 VDC and 0-10 VDC
outputs are field selectable via integral dip switches. Thermistor temperature outputs, along with setpoint
and override, are available as options for this configuration as well. The NSA-HH/CO2-R2 Series
provides data which can be used in conjunction with a Building Automation System or Demand Control
Ventilation to decrease energy consumption while creating a healthier indoor climate.
Applications: Schools, Office Buildings, Auditoriums, Gymnasiums, Shopping Malls, Theatres, Demand Control
Ventilation & Economizers

1
Accuracy is de-red after minimum three (3) ABC periods (1 period = 8 days) of continuous operations
2
In normal indoor air quality (IAQ) applications | Corrosive environments are excluded
3
Building CO2 levels must drop to 400 ppm same time during the week for ABC to work properly | If the building is occupied 24 hours /
day, ABC must be turned off
