before installation.
Important: When the thermostat is used to control a floor
heating element in connection with a wooden floor or
similar material, always use a floor sensor and never set the
maximum floor temperature to more than 35°C.
Please also note the following:
• The installation of the thermostat must be done by an
authorized and qualified installer according to local
regulations.

Installation Guide8
Do not place the thermostat in a way that it will be
exposed to direct sunlight.
Note: A floor sensor enables a more accurate
temperature control and is recommended in all floor
heating applications and mandatory under wooden
floors to reduce the risk of over-heating the floor.
Place the floor sensor in a conduit in an appropriate place
where it is not exposed to sunlight or draft from door openings.
• Equally distant and >2cm from two heating cables.
• The conduit should be flush with the floor surface -
countersink the conduit if necessary.
• Route the conduit to the connection box.
• The bending radius of the conduit must be min 50mm.
