Stop and read all manuals included with thermostat.
Connect your thermostat to the electrical box installed in part 3.2.
Connect the lines coming from the mats or junction box to the load ter-
minals on the thermostat, and the line coming from the circuit breaker to
the power terminals.
Connect the ground cables from the mats or junction box directly to the
ground line from the circuit breaker. (Green & yellow cable)
Connect the sensors for your thermostat. The
fl
oor sensor should be placed
roughly one foot from the wall. When placing the
fl
oor sensor, it is important
to make sure it’s located exactly between two heating ele-ments and more
than 5” from the folds (
fi
g A - page 18). The sensor cable must pass outside the
electrical box and follow the wall down to the
fl
oor.
Position the sensor cable such that it does not come in contact with
the
fl
oor heating wires. The sensor must be centered between two
fl
oor
heating ribbons for best temperature control.
Do not
staple the sensor head (the plastic end) to the
fl
oor. Doing so might
damage the sensor. Any damage might not be noticeable during testing but
can become apparent several days later.
At this point, it is recommended to take clear and thorough photos
of the entire system. These can be very valuable for later remodeling
work. Attach these photos to this manual, and leave them with the
homeowner after installation.
