Installation Instructions

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.
