Telaire T5100 Series
T5100 Wiring Diagrams
!WARNING!
T5100 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 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.

Duct-Mounting the Enclosures
T5100 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.
