Mounting
Location
Avoid mounting on outside walls or in direct sunlight.
Junction Box, (J-Box)
1. Pull the wire through the wall and out of the junction box,
leaving about six inches free.
2. Pull the wire through the hole in the base plate.
3. Secure the back plate to the box using the #6-32 × 1/2 inch
mounting screws provided.
4. Screw the plate firmly to the wall so the foam plate backing
is compressed about 50%.
5. Terminate the unit according to the guidelines in the
termination section.
6. Attach cover by latching it to the top of the base, rotating it
down and snapping into place.
7. Secure the cover by backing out the lock-down screws
using a 1/16" Allen wrench until it is flush with the bottom of
the cover.

both junction box and drywall installation.)

Drywall mounting
1. Place the base plate against the wall where you want to
mount the sensor.
2. Mark out the two mounting holes where the unit will be
attached to the wall. Drill a 3/16" hole in the center of each
mounting hole and insert a drywall anchor into the holes.
3. Drill one 1/2" hole in the middle of the marked wiring
through hole area.
4. Pull the wire through the wall and out the 1/2" hole, leaving
about six inches free.
5. Pull the wire through the hole in the base plate.
6. Secure the base to the drywall anchors using the #6 × 1"
mounting screws provided.
7. Screw the plate firmly to the wall so the foam plate backing
is compressed about 50%.
8. Terminate the unit according to the guidelines in the
termination section.
9. Attach cover by latching it to the top of the base, rotating it
down and snapping it into place.
10. Secure the cover by backing out the lock-down screws
using a 1/16" Allen wrench until it is flush with the sides of
the cover
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 sensor failure. To prevent these conditions, Daikin
recommends sealing the conduit leading to the junction
box with fiberglass.
Maintenance
Wipe as needed with a damp water only cotton cloth. Do not
paint.
Terminations
Daikin Applied recommends using shielded 22AWG for all
connections and a separate twisted pair for the power wire
connections. The shield should be earth grounded only at the
power source. Larger gauge wire may be required for runs
greater than 250'.
Note: Three conductors are required for the basic sensor
910247450, and four conductors are required for the
basic sensor with cool to warm 910247453.

All wiring must comply with the National Electric Code (NEC)
and local codes. Do NOT run any of this device’s wiring in the
same conduit as other AC power wiring. Tests show that fluctu-
ating and inaccurate signal levels are possible when AC power
wiring is present in the same conduit as the signal lines. If you
are experiencing any of these difficulties, please contact your
Daikin representative.
