• Check that the floor covering material is rated for use with underfloor heating

Usage recommendations

Always perform a resistance test on the cable before and after the installation of the floor covering to ensure the integrity of the heating element. Ensure that the thermostat is correctly configured to prevent the floor temperature from exceeding the limits recommended by the flooring manufacturer.
