Installation - Slab Sensor 079
Slab Sensor 079
The tekmar Slab Sensor 079 has a stainless steel sleeve which is designed for use in
concrete, thin-set or grout. The 079 is supplied with 10’ (3 m) of 2 conductor zipcord.
STEP ONE
INSTALLING THE SENSOR
New Installations
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 079 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
(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.

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.
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”

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.
