Note: A floor sensor is recommended in all floor
heating applications and mandatory to thin mats
under wooden floors to reduce the risk of
overheating the floor.
• Place the floor sensor in a protecting plastic conduit
in the floor construction in an appropriate place,
where the floor 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 flush with the floor
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.

network, that you would like to connect your
thermostat to. If in doubt contact network
administrator or internet service provider.
Identify your floor sensor type ( in kOhm).
Identify your installed heating output (in W),
from label on the heating element.
Power on the thermostat, and it will show “-“
in the display. Then it is ready to be configured using your
iPhone and Android device.
Open the Danfoss Smart™ App and follow the instructions
and set-up flow in the App.

IMPORTANT DURING SET-UP
Select whether only a floor sensor
or a combination of room and floor
sensor should be used.
A “room only” option is also available, but requires that you have to
break the small plastic seal on the
back of the display module, e.g. using a screwdriver; it will be possible
to set the maximum floor temperature up to 45°. Furthermore, it will be
possible to use only a room sensor.
However, this option is not recommendable due to an increased risk
of overheating the floor.
19Installation Guide
Danfoss ECtemp™ Smart
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.
Note: Please contact the floor supplier before changing
the maximum floor temperature and be aware of the
following:
• The floor temperature is measured there, where the
sensor is placed.
• The temperature of the bottom of a wooden floor
can be up to 10˚C higher than the top.
• Floor manufactures often specify the max. temperature on the top surface of the floor.
