1. When was the system installed?
2. Identify the model number(s) of each cable kit/mat that was installed. The model number appears on the
factory identification tag on the cold lead, retained within the junction box or electrical connection box,
behind the thermostat.
4. What type of controller (thermostat) was used? Was a relay/contactor used? If so, what is the model
number?
5. Provide the results of the Warm Tiles Cable and Mat Resistance Log from the original installation.
3. Provide the total square footage of the heated area.

11. What is under this floor? (Example: second floor, over crawl space, on slab, insulation)
12. For Cable Kits, what cable spacing was used?
13. What is the total height of the installation? How deep are the cables buried?
14. Have any flooring modifications or repairs recently been made in the area?
15. Was the system installed under floor obstructions? (Example: cabinets, vanity, plumbing fixtures,
shower); or – were any of these installed over the heated area after the cables were embedded in mortar?
16. Is it possible that the cable/mat was damaged during installation?
17. Where is the sensor wire bulb (thermistor) placed in the floor in respect to the heating cables? Are there
any heating vents or other heat sources near the sensor probe?

THERMOSTAT TESTING PROCEDURES:
If you are concerned that the system thermostat may not be operating correctly, please provide the following information:
Carefully measure the input voltage (between Line & Neutral (120V) or L1 & L2 (240V) – LINE or INPUT POWER) of the
thermostat. (Expected voltage to be approx. +120V or +240V AC):
Carefully measure the output voltage (between Line & Neutral (120V) or L1 & L2 (240V) – LOAD or TO HEATING CABLE)
of the thermostat when the thermostat is energized. Output voltage should match input voltage:
Please disconnect the power to the thermostat at the breaker BEFORE proceeding!
Remove the sensor wires from the thermostat terminals and measure the resistance between the sensor conductors.
Expected range is 7,000 to 14,000 ohms (measured at room temperature).
HEATING CABLE TESTING PROCEDURES:
If you are concerned that the floor heating cable/mat may not be operating correctly, OR if the thermostat or circuit breaker
ground fault protection is tripping, please provide the following information – use a separate form for each mat/cable for
which there are concerns:
Completely disconnect the heating cable from the back of the thermostat (LOAD or TO HEATING CABLE) before
proceeding with multi-meter and Megger measurements:
With an Ohmmeter (Multi-meter or DMM), check for either Open Fault or Short Fault condition. Please refer to
pages 5-7 for specific cable electrical specifications.
A. Check the resistance from one conductor of the heating cable/mat to the other conductor.
Value: Ohms * (Black & White for 120V AC; Black & Red for 240V AC)
B. Check the resistance from each conductor to the ground shield braid.
Value: Ohms *
Value: Ohms *
*Note: If the meter reading varies rapidly and will not stabilize, mark as “Unstable”.
A multi-meter will be required for the following test procedures:
CAUTION:
The following actions may present a shock hazard and should be done only by a qualified electrician.

CHECK THE HEATING CABLE’S PRIMARY INSULATION RESISTANCE VALUE:
C. Using a 500V DC Megger, check the insulation resistance from each conductor of the heating cable/mat to the
ground braid.
Value: MOhms *
Value: MOhms *
D. If the value in (A) above exceeds 5000 ohms (5 kOhms), megger between the conductors.
Value: MOhms *
*Note: If the meter reading varies rapidly and will not stabilize, mark as “Unstable”.
