Tile Floor Coverings
If a Slab Sensor 5110079 is to be installed into an existing tile floor with sufficiently
large grout lines, the sensor and wire can be installed in one of the grout lines between
the tiles. Select a low traffic area of the floor that is mid way between the heating
elements for the sensor location. Ensure that
the sensor is located in such a position that
the attached wire is able to reach to a suitable
junction location. Splices within the grout should
be avoided to ensure trouble free operation.
Remove the appropriate grout line and place the
sensor and wire in the floor. Re-grout the area.
Installing the Sensor to the Bottom of a Subfloor
If the sensor is to be installed to the bottom of a subfloor, cut a piece of 1” (25
mm) thick rigid insulation into a 6” (150 mm) by 6”
(150 mm) square. A groove 3/16” (5 mm) wide by
3/16” (5 mm) deep by 1-3/4” (45 mm) long should be
cut into the insulation to accommodate the sensor.
Place the sensor in the groove and sandwich the
sensor between the insulation and the subfloor. Use
a suitable fastening method to affix the insulation
to the subfloor.

Caution: Do not run sensor wires parallel to telephone or power cables. If the sensor
wires are located in an area with strong sources of electromagnetic interference,
shielded cable or twisted pair should be used or the wires can be run in a grounded
metal conduit.
The Slab Sensor 5110079 is supplied with 10’ (3 m) of cable. If a longer length
is required, 24 AWG or larger wire can be spliced onto the two wires from the
sensor. The splices should be properly soldered and protected in an accessible
junction box. Follow the sensor testing instructions given in this brochure and
then connect the wires to the control.
