Note for thermostat: A oor sensor is recommend­ed 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, coun­tersink the conduit
if necessary and
possible.

• Route the conduit to the connection box.

• The bending radius of the conduit must be min 50 mm.
