5 CHECK-UP
i Important
For the extended 10-year warranty to apply, you must perform these tests, record the results on the
warranty card, and retain a copy of the record.
You must perform the Insulation Resistance Test, the Heating Cable Resistance Test, and the Sensor
Resistance Test four times (Please refer to 4 installations) during the installation process.
5.1 Insulation resistance test
This test ensures that the insulating jackets of the cable are not damaged.
1. Connect the ground wire to the black lead and
both power wires to the red lead of the multi
meter.
2. Make sure the meter reads “open” or “infinity”
If you get a different reading, contact to the
distributor.
3. Record these readings on the warranty card.
5.2 Heating cable resistance test
This test measures the resistance of the BVF WFD heating cableand is used to determine circuit integrity.
1. Set your multi meter to the 200 or 2000 ohm
range.
2. Connect the multi meter leads to the black and
white cold lead wires.
3. Compare this resistance reading to the resistance
specified in the Product Selection. The value
should be within -10% to +10%. If you get a
different reading, contact to the distributor.
4. Record these readings on the warranty card.
i Important
Carry out the resistance reading of the NTC floor sensor of the thermostat prior to both placing and
covering. In case of BVF brand thermostats: ~10 kΩ 20°C.
