7.1 Commissioning Tests
Note: For the extended 15-year limited warranty to
apply, you must perform these tests, record the results
on the Commissioning Record, and retain a copy of the
record.
You must perform the Insulation Resistance Test, the
Heating Cable Resistance Test, and the Sensor Resistance
Test three times during the installation process:
1. Before you embed the QuickNet mat in mortar.
2. After you embed the QuickNet mat in mortar but before
you install the tile or stone.
3. After the tile or stone has been set.

Insulation Resistance Test

This test ensures that the insulating jackets of the mat are
not damaged. A low value indicates the mat has been dam-
aged and must be replaced.

1. Connect the ground wire to the black lead and both
power wires to the red lead of the multimeter.
2. Make sure the meter reads "Open" or "OL." If you get
a different reading, contact Tyco Thermal Controls at
800-545-6258.
3. Record these readings on the Commissioning Record.
Heating Cable Resistance Test
This test measures the resistance of the mat and is used to
determine circuit integrity.

1. Set your multimeter to the 200 ohm range.
2. Connect the multimeter leads to the black and white
cold lead wires.
3. Compare this resistance reading to the resistance speci-
fied in the Product Selection Table, on pages 8–9. The
value should be within ±10%. If you get a different
reading, contact Tyco Thermal Controls at 800-545-
6258.
4. Record these readings on the Commissioning Record.
Sensor Resistance Test
This test measures the resistance of the floor sensor and is
used to verify the sensor integrity.

1. Set your multimeter to the 200 K ohm range.
2. Connect the multimeter leads to the red and green lead
wires.
3. Make sure the meter reads between 9–25 KΩ. If you get
a different reading, contact Tyco Thermal Controls at
800-545-6258.
4. Record these readings on the Commissioning Record.
