Tile Floor Coverings
If installing a Floor Sensor (A3040079) 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 midway between the heating elements for the sensor
location. Ensure the sensor is located in such a
position that the attached wire is able to
reach to a suitable junction location.
Avoid splices within the grout 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 installing the sensor to the bottom of a subfloor,
cut a piece of 1" (25mm) thick, rigid insulation into a
6" (150mm) by 6" (150mm) square.
Cut a groove

" (45mm) long 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, use shielded cable
or twisted pair or run the wires in a grounded metal conduit.
The Floor Sensor is supplied with 10' (3m) 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 manual and then connect the wires to the control.
