User Instructions
Installing the Sensor
!WARNING!
Before performing service or maintenance opera-
tions on the systems, turn OFF main power switch-
es to the unit. Electric shock can cause personal
injury. Please read and follow the wiring instructions
precisely; miswiring may cause permanent damage
to the product.
Basic Installation
1. Separate the case into its front and rear sections.
2. Secure the rear section of the case to the wall or
junction box using the supplied screws, and make
necessary wire connections.
3. Select Voltage or Current output option and Voltage
range (0-10 V or 0-5 V) using the SW1 as shown on
the internal label (Figure 1) and Table 1.
Note: SW1 controls both CO2and Temperature
outputs simultaneously.
Factory default setting is Voltage outputs 0-10V.

!WARNING!
T5100-LED products have two terminal pins that are
connected inside the sensor to a common/ground:
pin #7 on the I/O terminal blocks and pin #2 on the
power block. Do NOT connect positive (hot) 24 VAC
power line to terminal number #2 of the terminal
block.
T5100 Wiring Diagrams
Caution!
The T5100-LED products are either 3-wire or 4-wire
type congurations, powered by either AC or DC
voltage. They are not 2-wire or loop-powered de-
vices. Wiring the units as 2-wire or loop-powered
devices will irreparably damage the sensors and
void the warranty

LED Display
The T5100-LED has a 5-color LED display that
shows the approximate CO2concentration. From
left to right, the display shows:
• Blue <800 ppm
• Green 800-1200 ppm
• Yellow 1200-1500 ppm
• Red >1500 ppm
• Two red >2000 ppm
Sensing Duct CO2Concentrations
Duct-Mounting the Enclosures
T5100-LED products can be installed inside the
return air ductwork, if needed. As an alternative,
please consider the T8031 unit. When mounting
these products inside the ductwork, seal the hole
around the wires and leave the duct insulation in
place to prevent condensation which may damage
the sensor.

Accessory Enclosures (cont.)
ABC Logic™ Self Calibration
System
ABC Logic™ (Automatic Background Calibration)
self calibration allows the sensor to continually re-
calibrate itself when the indoor concentrations drop
to outside levels while the building is unoccupied.
Generally a building must be regularly unoccupied
for 4 hours or more for this self-calibration system
to operate properly. Under these conditions, ABC
Logic™ should maintain sensor calibration over the
lifetime of the sensor. The ABC Logic™ should be
turned OFF where a building is continuously oc-
cupied 24 hours per day, or where there could be
signicant sources of non-occupant related CO2
such as greenhouses, breweries and other industrial
and food processing applications.
