Danfoss Heating
Congratulations with…
... your Danfoss floor heating system
Your property has been installed with a Danfoss electric floor
heating system. Danfoss is Europe’s leading floor heating
manufacturer, with over 45 years experience. We are confident that you will be satisfied with your new system.
Danfoss brings you…
An Invisible heating solution - A concealed heat source opens
up greater opportunities for decorating and furnishing.
Optimum comfort - Danfoss brings you the luxury and
comfort of a warm floor as well as a pleasant room temperature. Floor heating is the most comfortable type of heating
because it is based on the fact that warmth travels upwards;
pleasant warmth for your feet, body and head.
Low running costs – Thanks to the precise Danfoss thermostat and the placement of the heating elements right under
the floor surface the heat can be controlled optimally in
order for you to have the comfort you desire with minimal
energy use. Moreover electric floor heating is practically
maintenance free, in total keeping down the running costs.
A long lasting solution - We back-up our floor heating solutions with a ten year guarantee on all our mats and cables,
and a two year warranty on our thermostats. Practically
speaking you can count on Danfoss heating cables and mats
lasting as long as the house in which they are installed – and
that is without having to maintain them.
Hygiene - As Danfoss produce floor heating systems, only
very gentle air is circulating, and the amount of travelling
dust particles is reduced considerably; a great relief for
people with allergies or asthma. There are also no dangerous
fumes such as carbon monoxide generated by the system.

Install & configure the thermostat
Placement of EFETTM 535
When EFETTM 535 is used as a room
sensor, installation height should typically be
between 80-150 cm.
In wet rooms it should be installed on an even
surface, according to local building regulations.
At least 50 cm away from windows/doors that
will be left open occasionally.
Not on a wall where it will be subjected to
direct sunlight.
Not on the inner side of a wall facing the
outside.

Choose sensor combination
When installing the EFET™ 535 you need to choose
the type of heating and thus which sensors should be used. You have three options:
Comfort heating: Constant temperature on the floor in bathrooms and other rooms where a comfortable warm
surface is required.
Install the Floor sensor and choose only the Floor sensor.
Total heating: Control of room temperature in living
rooms etc. Install the Floor sensor and choose both
Floor sensor and Room sensor.
No floor sensor: A floor sensor is not present, and
cannot be installed. Choose Room sensor. (Not recommended).
Be aware that without a floor sensor, the temperature control can be less accurate, and overheating of the floor is of higher risk.
Danfoss recommends that a floor sensor is always
installed.
When the thermostat is used to control a floor heating
element according to EN/IEC 60335-1 and
EN/IEC 60335-2-96, always use the floor sensor
and never set the temperature limit above 35°C.

can be up to 10 degrees higher than the top. Floor manufactures often specify the max. temperature on the top
surface of the floor.
Please contact your floor supplier for maximum surface
temperature.

User’s guide to EFET TM 535
EFETTM 535 Introduction
EFETTM 535 is an electronic timer temperature controller,
specially designed for floor heating systems.
The EFETTM 535, once set, automatically adjusts the
heating to meet your comfort levels, regardless of changing
weather conditions by measuring the floor temperature and
combining it with the air temperature.
Even the programming of economy temperatures (i.e. lowering of temperature during the night and when you are out of
the house) is very simple. Just tell the EFETTM 535 your daily
rhythm and choose your program.
It also features a minimum floor temp. setting, eg. for
keeping your tile floors warm in summer as well.

Full: Indicating that the
thermostat is in comfort mode.
The 4 programs
4 different programs can be selected
Program 1
Manual mode. The temperature is maintained constantly 24 hours all week.
Program 2
The temperature is lowered to economy
temperature during the day and night
period all week.
INT
P2 is a day program for e.g. working days
where the temperature is decreased during
the middle of the day and at night. In the
morning and evening comfort temperature
is preferred.
Program 3
The temperature is lowered to economy
temperature during the night period all
week.
P3 is a program for days at home where
comfort temperature is preferred during the
day and a savings temperature at night.
Program 4
A week program where:
Mon – Fri: Program 2 and
Sat – Sun: Program 3
P4 is a week program with Monday-Friday as
workdays and Saturday-Sunday as days off.
The top 7 bars indicate Monday through
Sunday. On week days timer program 2 is
used and in weekends timer program 3.

If you increase/decrease the temperature
in a savings period
this change only
applies to this current period, not any future
savings periods. You might use this if you
are eg. working at home in timer program 4.
If you increase/decrease the tempera-ture
in a comfort period
this change applies
to all future comfort periods, until changed
again. From the perspective that you are
fine tuning the comfort temperature.

Disposal Instruction
All electric or electronic equipment and enclosed batteries
containing materials, components and substances that can
be harmful to people’s healthiness and to the environment, if
the waste is not handled correctly.
All electric or electronic equipment and batteries is marked
with the below crossed sign of a dustbin or garbage can. This INT
sign symbolize electric or electronic equipment and batteries
which are not allowed to be removed or disposed together
with the unsorted waste, but have to be gathered individually.
Some batteries are also marked with a chemical symbol Hg
(mercury), Cd (cadmium) or Pb (lead). These are very harmful
substances and for this reason it is very important to collect
these batteries.
As end user it is important for you to hand in your used
batteries for recycling. In this way you actively take part to
ensure that the batteries are reused according to the law and
do not unnecessary impact on the environment.
All countries have established collecting
points or other collecting arrangements,
where citizens free of charge can deliver
scraped electrical and electronic equipment
together with batteries for recycling. More
information can be obtained at your local
authorities.
