8.2.2 Electrical Fault Finding
If the system is not functioning properly, turn o the system and have a licensed, certified electrician perform
the following:
• Complete all steps of the installation process.
• Verify that all wiring connections, including grounding of the system, are correct.
• Check the sensor wire for proper ohm reading.
• Ensure all wires have been connected, including grounding of the system, in accordance with the wiring
diagrams.
• Verify that the breaker supplying power to the WarmlyYours thermostat is a non-GFCI circuit breaker
(Note: If using a thermostat not provided by WarmlyYours, a GFCI-circuit breaker may be required).
• Make sure multiple cables have been wired in parallel and not in series.
• Confirm that the thermostat is receiving the correct voltage and outputting the same voltage when
calling for heat.
• Using a well-calibrated, digital ohmmeter with good batteries, check the ohm resistance level of each
heating cable. Refer to sections 5.2.10 and 5.3 for instructions about how to attach the ohmmeter. Verify
that these values are within -5%/+10% at 20ºC (68ºF) of the resistance value listed on the product label. If
the measured values exceed the acceptable range, refer to the “Quick Reference Troubleshooting Guide”
in section 8.1. If the measured value is not within range of the original reading, the cable may have been
damaged in some way during installation.
If all of the above items have been completed and the system is still not operating correctly, then determine if
there is a break or a short under the floor.
8.2.3 Checking for Breaks or Shorts
To check for a break, measure the ohm resistance of each cable. When taking an ohm reading, ensure that
you do the following:
• Do not touch either of the probe ends with any part of your body. If the probe end is in contact with the
body, the meter will measure the internal resistance of your body, not the cable.
• Set ohmmeter to the proper scale (0 to 200 Ω for heating cable or 0 to 20,000 Ω for the sensor wire).
The ohm resistance readings should be within -5/+10% at 20ºC (68ºF) of the nominal resistance indicated by
the factory on the UL label. Refer to the “Quick Reference Troubleshooting Guide” in section 8.1. to determine
what the ohm readings indicate.
