9Installation Guide
Note for thermostat: A oor sensor is recommend-
ed in all oor heating applications and mandatory
to thin mats and under wooden oors to reduce the
risk of over-heating the oor.
• Place the oor sensor in a protecting plastic conduit
in the oor construction in an appropriate place,
where the oor is not exposed to sunlight or draft
from door openings.

≥
• Equally distant and
>2 cm from the
heating cables on
both sides.
• The conduit should
be ush with the
oor surface, coun-
tersink the conduit
if necessary and
possible.
• Route the conduit to the connection box.
• The bending radius of the conduit must be min 50 mm.
