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 " (25 mm)
thick rigid insulation into a 6" (50 mm) by 6"
(50 mm) square. A groove 3/6" (5 mm) wide by
3/6" (5 mm) deep by -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.
Subfloor
Tile Floor Coverings
If a Floor Sensor 079 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.

------------------------------------------------
The Floor Sensor 079 is supplied with 0' (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.
Floor Sensor 079 Wiring
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. If using shielded cable, the shield wire should be connected to the Com
terminal on the control and not to earth ground.
