STEP 4.8
Feed the sensor wire through the sensor conduit, leaving at
least 6"-8" of free lead length at the control electrical box.
Weave the sensor at least 1' into the mat area, halfway between
the heating wires, and secure it using hot glue. Do not cross
the heating wires. It may be necessary to chisel a small section
of the subfloor to accommodate the sensor, depending on the
thin-set thickness being used.
