Step 4. Install Thermostat Sensor
Cut an area of underlayment to push the sensor down so it is completely level with the mat. Tape the
floor sensor to the underlayment in an area at least 1 inches (2.5 cm) from any heated (black stripe) of the heating
mat. Do not allow sensor to contact mat.
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.
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.
NOTE:
