NOTE:
In a 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 and
premature failure of the sensor.
To prevent these conditions, seal
the conduit leading to the junction
box and seal the hole in the drywall
by using an adhesive backed, foam
insulating pad.
Mounting hardware is provided for
both junction box and drywall
installation.
1. Pull the wires through the
opening in the base plate.
2. For junction box installation:
Secure the base to the box
using the #6-32 x 1/2”
mounting screws provided.
For drywall installation: Drill
two 3/16” holes 3-1/4” apart on
center. Insert the drywall
anchors and secure the base
using the #6 x 1” sheet metal
screws provided.
3. Terminate the unit according to
the guidelines in Termination
on page 1.
4. Attach the cover by latching it
to the top of the base, rotating
the cover down and snapping it
into place.
5. Secure the cover by backing
out the lock-down screws
using a 1/16” Allen wrench until
they are flush with the bottom
of the cover.
