Feed the sensor wire to the SunStat
thermostat electrical box leaving at least
6"-8" of free lead length in the 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.
