Bulletin AQ-CDX

The Series CDX Carbon Dioxide Transmitter is a low cost and high

performing CO2 sensor. On-Demand ventilation using CO2 sensors

prevents energy losses from over ventilation while maintaining indoor air

quality. The potential for the greatest energy saving occurs in areas

where occupancy varies over the duration of the day. The Series CDX

Transmitters utilize a proprietary logic algorithm to eliminate the need for

manual calibration in applications where the indoor CO2 level drops to

outside levels during unoccupied periods.

MOUNTING

Push the tabs on the bottom of the housing to remove the cover. Mount

the back plate to the wall or junction box with the supplied screws and

make the necessary wire connections. Attach the cover to the back plate

by aligning the top clips and securing the bottom clips.

SELECTION OF VOLTAGE OUTPUT

Prior to wiring, verify that the voltage selection jumper is set to the

desired output type. For voltage output selection, the output can be 0 to

5 VDC or 0 to 10 VDC. Voltage (see below).

0 to 10 V Jumper Selected (left), 0 to 5 V Jumper Selected (right).
