Remote Sensor
The Floor Temperature Controller needs a remote temperature sensor. This sensor should be mounted in such a way that
the temperature which has to be controlled, can be measured
correctly. Lay sensor inside a protective tube (simplifies
replacement). The sensor lead can be extended up to 50 m by
using a cable and connections suitable for 230 V. Avoid laying
sensor cable alongside power cables, for example inside a
conduit.

Schlüter®-DITRA-HEAT-E
Advantages of Schlüter®-DITRA-HEAT-E:
Pleasant room climate
Based on mild radiated heat allowing climate control to suit.
Precise control
Due to the digital floor thermostat, preferred temperatures can be set easily and precisely
in every room.
Cost efficient
To buy, install and maintain.
Durable
Electrical floor heating systems have a long service life.
Maintenance free
There is no wear and tear, making the system virtually maintenance free.
Easy to retrofit
Quick and easy to install, low assembly height ideal for refurbishment.
(uncoupling mat incl. heating cable just 5.5 mm)
Simple to install
The heating wires are installed in the uncoupling mat, with tiles adhered in the thin set screed
directly above them. There is no need to trowel over unheated areas as in the case of conventional heating mats.
Practical solutions with complete packaged sets
Schlüter-Systems offers practical sets for common room configurations that include all
necessary system components in the right dimensions making selection and costs simple.
Suitable for allergy sufferers
The space is heated from the floor up, so that no allergens are distributed.
What are suitable uses of the electrical floor heating system?
Schlüter®-DITRA-HEAT-E is designed as a supplementary heating system, for example for:
 Heating tiled floors in living rooms and bathrooms in addition to a traditional heating
system (barefoot zones)
 Buildings with very low heating energy needs
(e.g. passive energy homes) as a backup
 Temporary heating of buildings that are only occupied occasionally,
e.g. weekend homes
Because of the higher operating costs, the electrical floor heating system is not suitable
to serve as a full-scale heating system. In those cases, effective area heating with the
ceramic thermal comfort floor Schlüter®-BEKOTEC-THERM is recommended.

Installation
Before installing our Schlüter®-DITRA-HEAT the following should be observed:
Substrates for Schlüter®-DITRA-HEAT:
Always check the substrates on which Schlüter®-DITRA-HEAT is to be installed to make
sure they are even, rigid, load-bearing, clean and compatible with the materials to be used.
Remove all surface components that may weaken the bond. Uneven or sloped areas must be
levelled prior to the installation of Schlüter®-DITRA-HEAT. To guarantee the effective heating of
the floor, thermal insulation (e.g. Schlüter®-KERDI-BOARD) should be included in all installations directly above ground or over unheated rooms.
Concrete: Concrete is subject to long-term form changes due to curing processes. Additional
tensions may result from the deflection of concrete and pre-stressed concrete. Schlüter®-DITRAHEAT uncouples the tensions between concrete and tile covering, which means that tiles can
be installed as soon as the concrete reaches a sufficient level of stability.
Cementitious screeds: With Schlüter®-DITRA-HEAT, tiles can be installed on green cementitious screeds as soon as they are ready to bear weight (please note that additional drying time
may be required for screed depths over 40 mm). In accordance with the applicable regulations,
cementitious screeds must be at least 28 days old and have a residual moisture level below
2 CM% before tiles can be installed. However, floating screeds and heated screeds are particularly prone to curling and cracking, for example because of weight loads and temperature
fluctuations.
Calcium sulfate screeds: According to the applicable regulations, calcium sulfate screeds
(anhydrite screeds) must have a residual moisture level below 0.5 CM% before tiles can be
installed. When Schlüter®-DITRA-HEAT is used, the tile covering is ready to be installed as
soon as the residual moisture level drops below 2 CM%. If necessary, treat the screed surface
in accordance with the codes of practice and manufacturer instructions (sanding, priming).
Schlüter®-DITRA-HEAT can be installed with dry-set adhesives or other suitable thin-bed adhesives. Schlüter®-DITRA-HEAT protects the screed against the penetration of moisture at the
surface. Calcium sulfate screeds are sensitive to moisture, making it necessary to protect the
screed from further moisture.
Heated screeds: Schlüter®-DITRA-HEAT may also be installed over heatedscreeds, with
the above material notes to be observed (cement, calcium sulfate). When Schlüter®-DITRAHEAT is used, the covering assembly may be heated up as early as 7 days after completion.
Starting from 25 °C, increase the supply temperature by a maximum of 5 °C a day to reach
an operating temperature of max. 40 °C.
Note: The use of Schlüter®-DITRA-HEAT over heated screeds allows for individual, partial
heating that is separate from the central heating system. This makes it feasible to switch off
the central heating system during seasonal transition periods. Furthermore, Schlüter®-DITRAHEAT can help cover peak loads.
Synthetic coverings and coatings: All surfaces must be weight-bearing and, if necessary,
pre-treated, to allow for the bonding of a suitable adhesive for permanent attachment of the
bonding fleece of Schlüter®-DITRA-HEAT. The suitability of the adhesive for the substrate and
for Schlüter®-DITRA-HEAT must be verified in advance.
6
Installation
Plywood panels: These materials are heavily affected by moisture (or large fluctuations in
humidity). It is therefore recommended to use plywood materials with special impregnation to
prevent the absorption of moisture (e.g. external grade plywood). Where available refer to the
codes of practice relevant to each country regarding the selection of products and the construction methods. In principle, panels can be used as a substrate on walls and floors in interior
areas. The thickness of the panels should be selected to ensure sufficient impact resistance
in conjunction with a suitable support structure. The panels must be sufficiently secured with
closely spaced screw fixings. All board joints should be fully supported by joists or additional
supports (noggins). Additional supports may prove necessary to provide a rigid and stable
substrate. Edge joints of approx. 10 mm must be kept open at the connections with adjoining
construction parts. Schlüter®-DITRA-HEAT neutralises the stresses in the tile covering and also
prevents the penetration of moisture.
Hardwood floors: The direct installation of ceramic coverings over hardwood floors is generally feasible, provided the floorboards have tongueand-groove connections, are sufficiently
load-bearing, and are tightly screwed down. The wooden substrate should have reached a
balanced moisture level prior to the installation of Schlüter®-DITRA-HEAT. Experts recommend
the installation of an additional layer of plywood. Uneven floors must be levelled before the
installation of other materials.
Pre-installation Planning
Step 1: Draw floor area onto graph paper removing unheated areas, e.g. bath, shower, sink, toilet and kitchen units etc.
Step 2: Calculate heating area with unheated areas removed from calculation.
Step 3: Choose heating area from left hand chart below. The heating cable must be calculated and installed 2 studs (60 mm) from all walls
and building elements, e.g. bath, toilet bowl etc.
Step 4: Choose total floor area from the centre chart ensure enough uncoupling mat is purchased to cover the whole floor area.

UK regulations for 230v supply e.g. outside of zone 0, 1 and 2.
a
Version A
b
Positioning the floor sensor
Version A: The floor sensor of the thermostat is positioned directly in the heated floor below
the uncoupling membrane Schlüter®-DITRA-HEAT in the conduit with the sensor sleeve. Run
the sensor through the conduit and then slide on the sleeve. The conduit and sensor sleeve
are included with the thermostat.
Version B: The sensor is installed directly in the newly installed uncoupling membrane
Schlüter®-DITRA-HEAT.
A spare sensor should be installed when adopting Version B installation, as the sensor
is embedded directly in the thin bed adhesive and cannot be changed.
Version B
Matting Installation:
Cut sections of Schlüter®-DITRA-HEAT-MA to size and fully embed the anchoring fleece
in to the adhesive using a 6 x 6 mm notched trowel. Immediately press the material into the
adhesive with a float or roller. Working in a single direction, and observe the curing times of all
materials. When installing rolled materials, it is best to align the studs of the Schlüter®-DITRAHEAT-MA with light tension at the time of embedding the material. The individual membranes
should be aligned next to each other with the stud structure lined up.
To prevent damage or detachment from the substrate, it is recommended to use walking
boards (especially in the centre of the assembly) to protect the installed Schlüter®-DITRAHEAT-MA membrane from mechanical impact.
Important: Testing of the heating cable, must be carried out prior to installation,
and again after installation of the heating cable and before tile/stone floor finish
is installed. To test the resistance of the heating cable use an electrical resistance
tester and place on both insulated cables. See page 11-12.
The heating cables can be installed immediately after adhering the uncoupling membrane
Schlüter®-DITRA-HEAT-MA, the heating cable should be installed and pressed into position
using a float. We recommend that a grove is prepared in a stud of the Schlüter®-DITRAHEAT-MA membrane to position the heating cable end and floor sensor.

The stud spacing of the uncoupling membrane is 3 cm. Heating cables should be installed
with a distance of 9 cm (every third stud); closer spacing is not permissible. We also advise
that the heating cable should be no closer than 60 mm (2 studs) from any building element,
e.g. wall, column, bath, toilet, etc. The heating cable should not cross.
Closer spacing may result in overheating and could damage the building structure.
Heating cable test:
The transition from the heating side to the cold connection cable (sleeve) is labelled as
shown. This cold side of the heating cable is 4 metres in length and can be connected directly to the thermostat or junction box. The minimum cut length is 1 metre.

Important: Testing of the heating cable, must be carried out prior to installation,
and again after installation of the heating cable and before tile/stone floor finish
is installed. To test the resistance of the heating cable use an electrical resistance
tester and place on both insulated cables. See page 11-12.
We recommend an insulation test is carried out prior to the embedding of the heating cables
to measure the resistance of the heating cables and enter your results into the enclosed log
on page 18.
Once the heating cables have been installed and tested, tiles can be installed in the thin bed
method, using a thin bed adhesive that meets the requirements of the floor covering. Using
a grout float to fill the groves of the uncoupling membrane in a single step (heating cables
and sleeves must be fully enclosed with tile adhesive) and then use a notched trowel to apply
the adhesive. A minimum 5 mm of covering (adhesive and tiles) is required above the heating
cable. Please observe the instructions regarding perimeter joints and connection joints in
product data sheet 6.4 Schlüter®-DITRA-HEAT.
Important: The assembly should be left for 7 days before turning on the electrical
heating system.

3. The sensor can be between the studs
of the matting, it is recommended that a spare sensor is
installed if using this method. Another method is to use
the plastic conduit supplied, along with the crimped piece
of copper tube, and then install the sensor immediatly
below the matting in the sub floor assembly. Ensure that
the sensor is pushed fully into the copper end tube, but also
that it can be withdrawn easily, for replacement purposes.

1 Principle of operation
The programmable Temperature Controller allows
programming switching events (up to 9) and temperatures
according to personal needs. After installation the device
automatically shows the time of day and the floor temperature. In AUTO mode, the heater will be automatically activated according to programmed time and temperature. Program
1 is activated see 8. The floor temperature will be controlled
according to the temperature measured by the remote sensor. The heater will be switched on when the temperature
drops below the current set-point.
2 Installation
Caution!
This device must be installed by a qualified electrician,
according to the wiring diagram on the device and in compliance with all applicable safety regulations. To maintain
compliance with Protection Class II, user access to the rear
of the device must be prevented... This device, is used to
control the temperature only in dry rooms, under normal
environmental conditions. This electronic device conforms
to EN 60730, It is an “independently mounted control” and
works according to operating principle 1C.
Connecting the remote sensor
Remote Sensor
The Floor Temperature Controller needs a remote temperature sensor. This sensor should be mounted in such a way that
the temperature which has to be controlled, can be measured
correctly. Lay sensor inside a protective tube (simplifies
replacement). The sensor lead can be extended up to 50 m by
using a cable and connections suitable for 230 V. Avoid laying
sensor cable alongside power cables, for example inside a
conduit.
There are 3 pre-set time/temperature programs in the controller. Pre-set program 1 (as shown below) is the default.
Therefore, if pre-set program 1 is the best program to suit the
application, there will be no need to change the time/temperature settings on the device.
To select another program see 9. G1.

· Only step on the heating cables to the extent that is
absolutely necessary for installation. Make sure suitable
footwear with rubber soles is worn.
· Cabinets with full floor contact as well as built-in cabinets may only be set up on unheated areas.
· No penetrating attachment parts (anchored screws for
doorstops etc.) may be set up in areas where heating
cables are installed.
· Additional layers over the covering, e.g. carpets or
bridges with thicknesses over 10 mm are not permissible as they can cause heat accumulation, which may
result in damage to the heating cables.
· Heating cables must be fully enclosed in tile adhesive to
prevent air gaps.
Application
Schlüter®-DITRA-HEAT is an impact resistant polypropylene foil with a special stud structure on one side for attachment of the matching system heating cables. A fleece
fabric is laminated on the underside for bonding with the
tile adhesive. Schlüter®-DITRA-HEAT is installed directly underneath ceramic tile or natural stone coverings for
floor heating. It is suitable as a back-up or primary heating
system (observe heating needs!) Due to its low assembly
height of approx. 5 mm, this heating system is particularly
suitable for the renovation of bathrooms, showers, kitchens etc. For reasons of thermal efficiency, covering thicknesses over 30 mm are not recommended.
Installation
The electrical heating system may only be installed by
a certified electrician (EN 60335-1). The heating system
must feature the option to disconnect all poles from the
mains with a contact clearance of at least 3 mm per pole.
An earth leakage circuit breaker (≤ 30 mA) must protect
against inadvertent contact.
See product data sheet 6.4 for suitable substrates for
Schlüter®-DITRA-HEAT.
Protective zones must follow VDE 0100-701.
It is impermissible to position the floor thermostat in
zones 0, 1 and 2.
Positioning the floor sensor
a) Schlüter®-DITRA-HEAT-E
b) Floor sensor, installed in a conduit
c) Floor thermostat.
The sensor position is equidistant from two heating cables (provide marking).
Version A: The floor sensor of the thermostat is positioned directly in the heated floor below the uncoupling
membrane Schlüter®-DITRA-HEAT in the conduit with
the sensor sleeve.
Run the sensor through the conduit and then slide on
the sleeve. The conduit and sensor sleeve are included
with the thermostat.
Version B: The sensor is installed directly in the newly
installed uncoupling membrane Schlüter®-DITRAHEAT.
A spare sensor should also be installed in this
case, as the sensor is embedded directly in the
thin set adhesive and cannot be changed, if it
malfunctions.
After positioning the floor sensor as described above,
apply suitable thin set adhesive over the substrate with
a notched trowel (6 x 6 mm).
Cut pieces of Schlüter®-DITRA-HEAT to size and fully
embed the anchoring fleece in the applied adhesive.
Immediately press the material into the adhesive with
a float or a roller, working in a single direction, and observe the curing times of all materials. When installing
rolled materials, it is best to align Schlüter®-DITRAHEAT with light tension at the time of embedding the
material. This is best done with an additional person.
The individual membranes or cuts are set tightly next
to one another.
· To prevent damage or detachment from the substrate,
it is recommended to use walking boards (especially
in the centre of the assembly for material transport)
to protect the installed Schlüter®- DITRA-HEAT membrane from mechanical impact.
The heating cables can be installed directly after adhering the uncoupling membrane Schlüter®-DITRAHEAT. Prepare a groove in the area of the soldered
cable end.
The stud spacing of the uncoupling membrane
a)
is 3 cm. Heating cables should be installed with
a distance of 9 cm (every third stud); closer
spacing is not permissible.
b) Closer spacing may result in overheating and can
damage building structures.
Alliteratively Schlüter-DITRA-HEAT can be installed directly over Schlüter®-KERDI-BOARD, which has been
correctly installed and waterproofed.
Heating cables may not touch or cross one another.
Make sure not to step on heating cables during the
installation work.
The transition from the heating cable to the connection cable (sleeve) is labelled with an imprint as shown.
An additional marking “Connection” is attached at the
transition. The imprint “COLD” is shown in the further
course of the connection cable. This thermistor (4 m) is
connected directly with the junction box or thermostat
without an extension. The thermistor may be cut to a
length of min. 1 m before the thermal transition (“Connection”).
Shortening heating cables is not permissible.
Thermistors must be installed in conduits in the floor
wall transition area to reach the wall socket. The thermistor ends have to be connected to the mains voltage
230 V~ that is switched through the thermostat setup.
The protective line conductors of the heating cables
are connected to the PE conductor. Schlüter® heating cables may only be operated with the Schlüter®DITRA-HEAT-E floor thermostat (Art.-No. HER 230 D/
BW). Perform an insulation test prior to embedding the
heating cables in the thin set adhesive to measure the
resistance of the heating cables and enter the value in
the enclosed test log.
Connecting the thermistors (temperature sensors)
Connect the ends of the thermistors in the wall junction box of the thermostat as shown.
Several heating cables are connected in parallel! The maximum permissible current at the
switch contact of the thermostat must be observed!
L = Terminal for switched phase (230V~) over
thermostat setup.

Note: Schlüter®-DITRA-HEAT has no waterproofing properties according to abP (German Certificate of National
Technical Approval).
Following the installation of the heating cables, Schlüter®DITRA-HEAT must be fully covered with Schlüter®-KERDI
for waterproofing; see the corresponding product data
sheet 8.1 for Schlüter®-KERDI.
Once the heating cables have been installed and tested, tiles can be installed in the thin set method, using
a thin set adhesive that meets the requirements of the
covering. It is helpful to fill the grooves of the uncoupling
membrane in a single step, using the smooth side of
the notched trowel (heating cables and sleeves must
be fully enclosed by tile adhesive) and to then use the
notched trowel to apply the thin set adhesive. The tiles
are fully embedded in this layer. Choose a notched
trowel to match the tile format. The curing times of the
thin set adhesive must be observed.
· Please observe the instructions regarding perimeter
joints and connection joints in product data sheet 6.4
Schlüter®-DITRA-HEAT.
Note: The thin set adhesive and the covering materials
used in conjunction with Schlüter®-DITRA-HEAT must
be suitable for the corresponding application and meet
the applicable requirements.
Covering the heating cables
VDE/EN regulations (60335-2-96-2002) mandate a
covering thickness of 5 mm over the heating cables.
A permanent temperature resistance of 50° C must be
met.
Documentation
The following documentation must be issued to the
system operator:
· Installation instructions with completed test log,
