2 General information
The ECdry oor heating system consists of a
foam/carpet heating element with heating
mats inside. The system must always be con-
trolled with a ECtemp, as it is an important
part of the safety and overheating protections
system.
The ECdry oor heating system can be used
under wooden oors such as parquet and
laminate. Please check the specications
with your supplier of these products.
ECdry has been tested and approved with
ooring materials with insulation values
from 0,07 to 0,18 m² K/W.
For best performance of the oor heating sys-
tem, keep the insulation value from the ECdry
heating unit to oor surface as low as possible.
The ECdry oor heating system has been
developed to the dry application area for
underoor heating.
It is applicable for wooden and concrete
oor constructions with the two output
ranges 55 W/m² and 100 W/m².

5 Designing the layout
Draw a oor plan of the room and determine
the most logical location for the control sys-
tem and the position of the oor heating mats.
Consider the placement of the thermostat to
get the most convenient access and make sure
the necessary power supply is available.
The output cord from the control system will
go into the right side of the heating element,
so you should start laying the rst heat ele-
ment on the right side of the oor and work
towards the left side. Remember to keep
at least 70 mm of free space between the
skirting/wall and the rst heating element
for the plug-in connection between the oor
heating element and the control system. Use
the ller material to ll this space afterwards.
Examples of calculations are provided below
to help you work out how many ECdry oor
heating mats are required. All ECdry oor
heating mats are one metre wide and the
standard length varies from one to ve me-
tres. Reduce the length of the elements to
the required size as shown in the table.
Example 1: When the area is 5 m wide and 6 m
long, you will need 5 × 5 m ECdry oor heating
mats, plus 5 square metres of ller material.
Example 2: When the area is 3.75 m wide
and 7.10 m long, you will need 6 × 4 m
ECdry oor heating mats. Cut the 4 m long
elements down to 3.75 m. You will also need
0.38 square metres (buy 1 square metre) of
ller material. A ECdry oor heating exten-
sion cord is available as an accessory. Use
the cord in the event that you are unable
to make a direct connection between two
adjacent oor heating elements or between
the 1
st
mat and thermostat kit. The exten-
sion cords must only be placed in the ller
material and not on top of the heating ele-
ment. The extension cords can be extended
with each other if necessary (if you need
3 m extension cords you can use 2 m + 1 m
extension cords).
Example 3: When placing the elements after
each other you should always cut away the
cold end (25 cm) of the element to avoid
cold zones.

Installation Guide Danfoss ECdry Touch Kit
Installing Supply Cord or Extension Cords:
The cords must only be placed in the ller
material and not over/in the heating element.
The ller material shall be cut so it envelopes
the cords. The ECdry X can withstand maxi-
mum 10 A.
Make sure that no hot spots develop when
using the oor heating system. Avoid hot
spots by ensuring that the heat from the oor
heating is homogeneously released to the
area you wish to heat and that there is free
space (ventilation) under the furniture.
When designing the layout, make sure not
to install ECdry heating element under per-
manent or built-in cupboards or re places/
ovens. ECdry have to be separated from
other heat sources such as chimneys. Instead
ECdry ller material should be used.

1 m² 1 m 0,5 m
2 m² 2 m 1,5 m
3 m² 3 m 2,5 m
4 m² 4 m 3,5 m
5 m² 5 m 4,5 m

1�1 Preparing the base
Before you start installing the product,
please ensure that the oor is:
• Permanently inexible
• Dry
• Flat and regular
• Dust- and fat-free
• Free from any sharp objects
Use a powerful vacuum cleaner to remove
all dust from the oor.
Remember to install a 0,20 mm vapour barrier on the suboor
before rolling out the heating mats.

1�1 Calculating current limitations
The ECdry oor heating system should be
connected in accordance with national stan-
dards and wiring rules.
Maximum current per ECdry system is 10
Ampere.
In the following tables you will nd maxi-
mum heated surface per ECdry Touch Kit
and an overview of the total power output
of the systems.

Installation Guide Danfoss ECdry Touch Kit
1�1 Connecting the ECdry elements
Bulges on the element may occur, but will
disappear when the ECdry system is heated.
All elements are equipped with an end stop
to insulate the connector and protect the
connection against moisture. Remove the
end stops with the special tool, just before
making the connection with the next heat-
ing mats. If all end stops are taken out at
once, remember to leave the end stop in the
last element.
Connect the plug-in connection of the second
element into the plug-in connection of the rst
element. Put the male and female connector
together by hand before using the connec-
tor tool to push the elements tight together.
Check that the plug-in connection ts correctly
and permanently. Continue with the subse-
quent elements in the same manner.
Make sure that all plug-in connections t
straight and without any mechanical stress.
Discontinue the oor heating installation
process in the event of damage to one or
more components. Incorrect installation may
cause problems and/or defects to the oor
heating mats. Please take precautions not to
drop sharp objects on the heating mats.
Use the enclosed aluminum tape to x mats
to each other in order to secure connec-
tions and to avoid movement of mats. Place
aluminum tape in two positions: directly on
connections (between mat connections and
in the opposite end of the mat). In addition
x 1st mat connection and output cord from
ECdry Touch Kit.
Make sure that the end stop in the last element
is in place before the oor covering is laid. Keep
the end stops if you intend to remove/reposi-
tion your oor heating system later.

Installation Guide Danfoss ECdry Touch Kit
1�1 Filling up the remaining space
At this point all connections between the
elements should be aligned and connected
and as much of the oor as possible should
be covered with ECdry elements. The space
without ECdry heating mats should be cov-
ered with the ECdry Filler Material to ensure
an even and homogenous oor surface.
A knife, a lineal (to cut along) and a wooden
plate (behind the ECdry element) can be
used when cutting the ECdry Filler Material
to avoid cutting into the electrical parts and
ensuring a straight cut.
To be certain that the distribution of the
oor heating mats in your room is correct,
we suggest you make everything t before
you secure the elements permanently. It is
most important to make sure that all plug-in
connections are perfectly aligned to allow
the ow of electricity from one element to
the next. Put the oor heating mats plus any
ller materials down as shown in the lay-out.
Once you have correctly positioned all oor
heating mats and you have cut the ller
material to size, you can proceed with the
permanent installation as explained in the
following steps.
Fit the output cord
Cut a piece of material from the ller mate-
rial to embed the output cord between the
ECdry Controller and the ECdry heating mat.

18 | Danfoss © | 2020.07 AN324050550815en-000201
Installation Guide Danfoss ECdry Touch Kit
1�1 Mounting the ECtemp Thermostat
The electrical installation must be done by
an authorised electrician. Mount the ECtemp
thermostat to the wall. The ECtemp should be
installed in accordance with the instruction
manual supplied with the thermostat and the
ECdry Touch Kit.
Cut a piece of material from the ller mate-
rial to make room for the ECdry Supply Cord
between the ECtemp thermostat and the
ECdry Touch element.
Make sure not to fold and/or squeeze the
cord between the thermostat and the oor
heating element but make room for the cord
in the ller material. Minimum bending
diameter is 5 cm.
To place the sensor in the right spot, remove
the cut-away area in the ECdry Touch
heating element and place the sensor
down into the groove.
Fix the sensor to the heating mat with the
enclosed aluminium tape.
1�1 Checking the ECdry oor heating system
Check that all work has been carried out in
accordance with directions before testing
the ECdry oor heating system. Testing
may commence when everything has been
correctly connected. Read the directions for
the control system before you proceed. Set
the temperature at maximum 35 °C. After a
short while you will notice the ECdry oor
heating mats are warming up.
If the oor heating mats are not warming
up to the same temperature, the plug-in
connections should be checked once again.
Remember to switch o the ECdry system
before checking.

Installation Guide Danfoss ECdry Touch Kit
1�1 Laying the top oor
Please consult the oor manufacturer to
ensure that the oor covering is suitable for
oor heating. The nal oor covering (lami-
nate or parquet) can be laid when the ECdry
heating system has been tested.
According to ISO 13732-2,
the comfortable oor sur-
face temperature depends
on the ooring material.
Soft wood (pine)
22.5 - 28°C
Hard wood (oak)
24.5 - 28°C
However, observe the maximum oor
surface temperature according to the oor-
ing manufacturer. For most wooden oor
products, the temperature is usually around
27 °C. All temperature settings must be set
some degrees higher to compensate for the
heat resistance in the top ooring.

1�1 Warning label
The warning label that is included in the
ECdry Touch Kit must be lled out and
placed in the distribution board. For future
reference it is important to ll in, which
room and how many ECdry elements that
have been installed, by whom and the
installation date. Furthermore, the room
should be drawn in the manual so it is easy
to see how the elements have been posi-
tioned in the room in the future. See layout
