STEP ONE INSTALLING THE SENSOR

New Installations

Thin-Set or Thin-Pour Applications

If the floor covering is to be installed over eithera thin-set or thin-pour material of sufficientdepth, the 079 slab sensor can be placed

directly into either the thin-set material or thethin-pour material and covered over. Ensure

that the sensor is located in such a position thatthe 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 locatedmid way between the heating elements to ensure a proper temperature reading.

Cables

thin-pour should be avoided to ensure trouble free operation. The sensor should be locatedmid way between the heating elements to ensure a proper temperature reading.

Thin Floor Coverings (lessthan 3/8” (10 mm))

If a thin floor covering is to be installed directly

to the subfloor, a groove 1/8” (4 mm) wide by1/16” (2 mm) deep can be cut into the surface of

the subfloor to accommodate the wire for thesensor. Ensure that the sensor is located in

such a position that the attached wire is ableto reach to a suitable junction location. Splicesunder 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”

SLAB SENSOR 079

The tekmar Slab Sensor 079 has a stainless steel sleeve which is designed for use inconcrete, thin-set or grout. The 079 is supplied with 10’ (3 m) of 2 conductor zipcord.

Thick Floor Coverings (great-er 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 by1/16” (2 mm) deep can be cut into the backof the flooring material to accommodate the

wire for the sensor. Ensure that the sensor islocated in such a position that the attached wireis 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 theheating 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.

Retrofit Installations

Tile Floor Coverings

If a Slab Sensor 079 is to be installed into an

existing tile floor with sufficiently large grout

lines, the sensor and wire can be installed inone 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 insuch a position that the attached wire is ableto reach to a suitable junction location. Splices

within the grout should be avoided to ensuretrouble free operation. Remove the appropriategrout line and place the sensor and wire in thefloor. Re-grout the area.

Installing the Sensor to the

Bottom of a SubfloorIf the sensor is to be installed to the bottom ofa 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 shouldbe cut into the insulation to accommodate thesensor. Place the sensor in the groove and

sandwich the sensor between the insulation and

the subfloor. Use a suitable fastening methodto affix the insulation to the subfloor.

STEP TWO WIRING AND TESTING THE SENSOR

Caution: Do not run sensor wires parallel to telephone or power cables. If the sensor wiresare located in an area with strong sources of electromagnetic interference, shielded cableor twisted pair should be used or the wires can be run in a grounded metal conduit.

The Slab Sensor 079 is supplied with 10’ (3 m) of cable. If a longer length is required, 24AWG or larger wire can be spliced onto the two wires from the sensor. The splices shouldbe properly soldered and protected in an accessible junction box. Follow the sensor testinginstructions given in this brochure and then connect the wires to the control.
