Thick Floor Coverings (greater than 3/8” (10 mm))
If a thick floor covering is to be installed directly to the subfloor, a groove 1/8” (4
mm) wide by 1/16” (2 mm) deep can be cut into the back of the flooring material to
accommodate the wire for the sensor. Ensure that the sensor is located in such a
position that the attached wire is able to reach to a suitable junction location.
Splices under the floor covering should be avoided
to ensure trouble free operation. A groove 3/16”
(5 mm) wide by 3/16” (5 mm) deep by 1-3/4” (45
mm) long should be cut to accommodate the
sensor. The sensor should be located mid way
between the heating elements to ensure a proper
temperature reading.
NOTE: If it is not practical to cut a groove in the
surface covering, follow the installation method
used for thin floor coverings.
Slab Sensor 5110079 Installation
Thin-Set or Thin-Pour Applications
If the floor covering is to be installed over either a thin-set or thin-pour material of
sufficient depth, the 5110079 slab sensor can be placed directly into either the
thin-set material or the thin-pour material
and covered over. 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 thin-set or thin-
pour should be avoided to ensure trouble free
operation. The sensor should be located mid
way between the heating elements to ensure
a proper temperature reading.

Thin Floor Coverings (less than 3/8” (10 mm))
If a thin floor covering is to be installed directly to the subfloor, a groove 1/8” (4
mm) wide by 1/16” (2 mm) deep can be cut into the surface of the subfloor to
accommodate the wire for the sensor. Ensure that the sensor is located in such
a position that the attached wire is able to
reach to a suitable junction location. Splices
under the floor covering should be avoided to
ensure trouble free operation. A groove 3/16”
(5 mm) wide by 3/16” (5 mm) deep by 1-3/4”
(45 mm) long should be cut to accommodate
the sensor. The sensor should be located mid
