Installing the Sensor

!WARNING!

Before performing service or maintenance operations on

the systems, turn OFF main power switches 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 CO

simultaneously.

T5100 Wiring Diagrams

!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.

Caution!

The T5100-LED products are either 3-wire or 4-wire type
configurations, powered by either AC or DC voltage. They are
not 2-wire or loop-powered devices. 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

CO2 concentration. From left to right, the display shows:

• Blue <800 ppm

• Green 800-1200 ppm

• Yellow 1200-1500 ppm

• Red >1500 ppm

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.
