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. Mount the Controller on the base by aligning the top clips and then
securing to the bottom clips. Secure the Ventostat with the supplied
set screw. A one-minute stabilization warmup will take place.

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.
