Step 4. Install Thermostat Sensor
A floor sensor comes with the recommended thermostat control.
The sensor wire can be installed without a conduit or in a conduit
separate from the electrical power leads if conduit is required
by code. Open a second knockout in the bottom of the thermostat
box. Feed the sensor (and conduit, if including) through the knock-
out, down the wall cavity, through the opening in the bottom plate.
Temporarily tape the sensor to the slab or subfloor in a location
approximately 6” to 12” from the wall---final location of sensor after
mat installation will be taped down at the edge of or in between
two mats so that the sensor is not directly above a heating mat.
Butt the sensor up against the side of the mat for best results.
*The sensor is located in the thermostat packaging.
Step 5. Prepare Mats
If installing cut-to-length mats, you first need to prepare them for use, as follows:
1. Using the diagram you made earlier, cut the heating element to length using scissors.
2. Do not cut the end with wired connections; only cut the opposite end (without wiring).
3. Insulate the cut ends with Kapton Disks.
Step 5a. Radiant Heat Mats
Since the boxed kit for the 2-in-1 mat is designed to create 2 mats, both ends of the kit length have factory
installed lead wires. The end result is it will create 2 mats out of 1 boxed length. The mat MUST be cut into 2
desired lengths in order to operate correctly. Similar as in step 5 you will need to properly prepare the 2-in1
as follows:
1. Using the diagram you made earlier, cut the heating element into 2 desired to lengths using a scissors.
Ensure not to cut into black stripe and stay only on the dotted line when cutting to lengths.
2. Insulate the 2 created mat cut ends with the supplied Kapton Disks on the exposed bus bars.
There will be 4 bus bars to cover after the cut.
Sensor is thicker than the heating mat. If necessary,
saw a groove in the underlayment between the mats,
to recess the sensor to the level of the mat. Use
duct tape to secure the sensor in the groove. Do not
damage the sensor. Ensure the sensor is set down so
it is level with the mat and not on top of the mat.
NOTE:
Cut only through the clear
area between the heating
stripes. NEVER cut closer
than ¼ inch (6 mm) to the
heating stripes and DO
NOT cut into the heating
stripes themselves.
