Mounting
Ensure the plate does not touch the wall when it is mounted as this will lead to slower response
rates when the environment changes.
Mounting hardware is provided for both junction
box and drywall installation.
Junction Box
1. Pull the wire through the wall and out of the
junction box, leaving about 6” free.
2. Terminate the unit according to the
guidelines in Termination on page 1.
3. Secure the plate to the box using the
#6-32 x 1/2” mounting screws provided
or with security screws which are
sold separately. (Call BAPI or visit the
Accessories section of our website for
security screw ordering.)
4. Tighten screws until the foam gasket
on the back plate is compressed about
50%. Ensure the plate doesn’t touch the
wall (Fig 5).
Note: Louvered wall plates require a mounting adapter bracket for J-Box mounting. The bracket is not shown in the
diagram above but is included with any louvered wall plates ordered from BAPI.

Drywall Mounting
1. Place the plate against the wall where you want to mount the sensor and mark out the two mounting holes.
2. Drill two 3/16” holes in the center of each marked mounting hole. Insert a drywall anchor into each hole.
3. Cut hole between the mounting holes that clears the apparatus mounted on plate. Pull the wire through the wall hole
cut in step 2, leaving about 6” free.
4. Terminate the unit according to the guidelines in Termination on page 1.
5. Secure the plate to the drywall anchors using the #6 x 1” mounting screws provided. Tighten screws until the foam
gasket on the back plate is compressed about 50%. Ensure the plate doesn’t touch the wall.
Note: In any wall-mount application, the wall temperature and the temperature of the air within the wall cavity can cause
erroneous readings. The mixing of room air and air from within the wall cavity can lead to condensation, erroneous
readings and premature failure of the sensor. To prevent these conditions, seal the conduit leading to the junction box or
ll the box with insulation.

J-Loop Termination Technique
Incorporating a “J-Loop” (also known as a drip loop) into all terminations adds an additional layer of protection against
moisture and oxidation by directing moisture away from the connection. The idea is to place the wire junction as high as
possible and form a “J” with the leadwires. The bottom of this “J” should be below the junction point. Any moisture that collects on the leadwires is pulled downward by gravity to the bottom of this loop and away from the junction.

Termination
BAPI recommends using twisted pair of at least 22AWG and sealant lled connectors for all wire connections. Larger gauge
wire may be required for long runs. All wiring must comply with the National Electric Code (NEC) and local codes.
Do NOT run this device’s wiring in the same conduit as AC power wiring. BAPI’s tests show that uctuating and inaccurate
signal levels are possible when AC power wiring is present in the same conduit as the signal lines.
BAPI recommends wiring the product with power disconnected. Proper supply voltage, polarity, and
wiring connections are important to a successful installation. Not observing these recommendations may
damage the product and will void the warranty.
Sensor Termination:
Terminate the sensor wires to your controller wires using BAPI sealant lled connectors. The wallplate’s foam back insulates the temperature sensor from the wall temperature and/or conduit drafts.
