Prior to wiring, verify that the current/voltage selection jumpers (PJ1, PJ2, and PJ5)

are set to the desired output type. Refer to Figure 2 to locate the selection jumpers.

See Figure 3 for diagram of the current/voltage selection jumper. For voltage output

selection, the output can be 0 to 10 VDC, 0 to 5 VDC, 2 to 10 VDC or 1 to 5 VDC.

See Figure 4 for the type of voltage output selection jumper (PJ5).

n the CDT, the transmitter may be wired for current or voltage output for both carbon

ioxide and temperature. On the CDTR, the transmitter may be wired for current or

oltage output for both carbon dioxide and humidity. The transmitter can be powered

with either 16 to 35 VDC or 19 to 28 VAC. Wire the transmitter according to Figure 5.

or models that are ordered without an integral LCD display, remote display Model

A-449 can be used to display the temperature, humidity, and carbon dioxide. The mini

USB plug of the remote display plugs into the receptor on the side of the housing.

After a short warm up time, the display will begin to show the current temperature and

carbon dioxide measurements unless configured by the user to show humidity and

carbon dioxide, only temperature, only humidity, or only carbon dioxide.
