We recommend always installing the floor sensor in a corrugated tube / empty tube so that it can be easily replaced in case of damage. The empty conduit has a diameter of approx. 16mm. Appropriate recesses must be chiselled out in the wall and floor.
The sensor itself should protrude at least 10cm on or under the heating film so that the temperature can be measured correctly. If a heating mat is used instead of a heating film, the sensor should be positioned between two heating wires. Here too, the sensor should protrude at least 10cm into the heating area.
