Test for Heating
1. Turn on the breaker and adjust the
thermostat so that the system begins
heating.
2. After the system has been on for several
minutes, run your hand over the heating
mats to ensure that they are warm.
3. If the mats do not become warm, double
check all wiring and re-perform the
electrical tests above (after turning off
power at the breaker).
Troubleshooting
It is important that this manual be followed during the
installation procedures and that all warnings be followed.
Wiring should be performed by a licensed electrician in
accordance with all applicable building and electrical codes
during the installation as well as for any trouble shooting of
the system. Failure to do so voids warranty.
A test of the system to make sure all mats are heating properly
is recommended prior to installation of finished flooring. The
manufacturer will not be responsible for the replacement
of the floor heating system if the system operation was not
checked and verified prior to installation of the flooring.

Installation & Owner’s Guide 15
Individual Mat
Not Warming
Verify that all leads from all mats are connected together to power source. Areas within a mat
that are not heating could be the result of damage and will require the mat to be replaced.
Slow to Heat Installations on concrete slabs can require a period of several days to warm up to desired temperature
especially if the slab is uninsulated in a cold climate. Set Thermostat to maximum heat to allow system
to continue running until it becomes warm. Then adjust thermostat down if needed. Verify floor tempera-
ture sensor is not directly on top of heating element causing the thermostat to shut off more frequently.
System Too Hot Adjust thermostat
Verify that correct voltage is being applied to heating elements rated for 120V Service.
Verify that thermostat has not been bypassed.
If necessary, reposition floor temperature sensor.
Thermostat GFCI If the thermostat trips and will not re-set, check the following:
System MUST be on a dedicated branch circuit separate from any other electrical devices which
could overload the circuit or create interference issues resulting in the GFCI to trip.
Check electrical connections to verify leads from all mats are wired in parallel (black to black / white
to white / red to red) and all connections are tight and properly insulated against grounding.
Check leads from mats to verify no nicks or cuts have occurred during construction that may
be causing a short. For further assistance with GFCI problems call 888-WARM PAD.
Thermostat Issues Refer to the thermostat manufacturer’s documentation.
Symptom Corrective Actions
The mats will generate a low, comfortable warmth. If area is cold during installation it is likely that the mats will
not seem warm so you will have to rely on the electrical tests. If the mats do not become warm, double-check
all wiring and again perform the electrical tests above (after turning off power at the breaker).
Disclaimer: The mats will generate a low, comfortable warmth, the
mats are designed to heat the ooring not the air. If area is cold during
installation it is likely that the mats will not feel warm to the touch so
you will have to rely on the electrical resistance tests alone or the use
of an IR thermometer temperature sensing device.
