!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 congurations, 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.

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
significant sources of non-occupant related CO2
such as greenhouses, breweries and other industrial
and food processing applications.
