Install Steps

Installation Recommendations

It is strongly recommended to insert the cable and sensor into a nonconductive conduit embedded in the floor.  The end of the conduit must be sealed and the conduit placed as high as possible in the concrete layer.  Alternatively, the sensor can be embedded directly in the floor.  The floor sensor must be centered between loops of heating cable.

The two wires from the sensor to the thermostat must be kept separate from high voltage wires/cables. Place the sensor cable in a separate conduit or segregate it from power cables in some other way. Never use two vacant wires in a multi-core cable.

Installation must comply with national and/or local electrical codes.
