Troubleshooting SunTouch Mat Installations
If you are not qualified to do electrical installations, we recommend hiring a qualified, licensed electrician to install Mat and related electrical components. If you, or your electrician, have problems please read below for troubleshooting tips. Any troubleshooting work should be done with the power removed from the circuit, unless otherwise noted.
1. Mat resistance measurement is different from the UL label.
a) The meter must be able to read from 0 ohms to 1000 ohms.
b) Does the meter need to be calibrated?
c) Is the meter digital? If not, consider a digital meter. The readings will be more accurate.
d) Have you checked the batteries? Low batteries will give bad readings.
2. The control is not operating.
a) Check the Mat resistance with your digital ohm meter again.
b) Have you supplied 120 volts to the control?
c) If using the SunStat, are the sensor wires connected to the control? They must be connected for the FloorStat to operate. (Unless it is the NEW 500670 model)
d) Has the SunStat’s GFCI circuit “tripped” indicating a possible wiring problem?
3. The Mat doesn’t get warm.
a) Have you supplied 120 volts to the control? Check electrical schematics and control instruction.
b) Are the sensor wires connected to the FloorStat control? Check electrical schematics and control instructions.
c) Use your digital ohm meter to confirm that the sensor wire, not the Mat, has a reading of 10,000 ohm (10K) at 70 degrees F.
d) Check the Mat resistance with your digital ohm meter again and compare to UL tag.
e) If using a wall outlet GFCI, read the instructions carefully to make sure the “line” (power supply) and “load” (Mat) are properly wired.
f) If using more than one Mat, make sure both are wired in parallel (white-to-white, black-to-black, green-to-green) and connected to the control.
4. The ohm meter shows the Mat resistance is open or at infinity.
The Mat has been damaged and must not be energized. If the Mat has been damaged, stop immediately and look for the damaged area. If this damaged area cannot be found, take ohm readings between the black and white wires (Blue replaces White for 240v), black and green wires, and white and green wires and record these readings and contact the factory for assistance toll free 888-432-8932.
