CO2 Occupancy Sensing Switch Instruction / Installation Guide

The A/CO2 transmitters monitor carbon dioxide (CO2) levels in industrial and living environments from 0 to 5,000 ppm. The concentration of CO2 is a good indication of the indoor air quality (IAQ). All units come with both a 4-20 mA and 0-10 VDC analog output as well as a relay output with an adjustable setpoint and deadband (Hysteresis). Units come standard with LCD displays as well.
