INTRODUCTION
The FTE 400 All-in-one is an electronic on/
off thermostat for 1 or 2 NTC sensors located
externally.
An All-in-one thermostat for many application
types:
• Electrical floor heating
• Frost protection
• Ice and snow melting
• Cooling
The thermostat should be DIN rail mounted.
This thermostat can be used as a controller for
electric room heating pursuant to EN50559.
IMPORTANT SAFETY INSTRUCTIONS
Warnings
To avoid electric shock, disconnect
the heating system power supply at
the main panel before carrying out any
work on this thermostat and associated
components.
Installation must be carried out by qualified per-
sonnel in accordance with appropriate statutory
2
regulations (where required by law).
Installation must comply with national and/or
local electrical codes.
Cautions
This instruction must be observed,
otherwise the liability of the manufac-
turer shall be voided.
Any changes or modifications made
to this thermostat shall void the liability of the
manufacturer.
Maximum product lifetime is achieved if the
product is not turned off but set at the lowest
possible set point / frost protection when heat is
not required.
Notice
The language used in the original
documentation is English.
Other language versions are a trans-
lation of the original documentation.
The manufacturer cannot be held liable for any
errors in the documentation. The manufacturer
reserves the right to make alterations without
prior notice.
Content may vary due to alternative software
and/or configurations.
DISPOSAL AND RECYCLING
Environment and recycling
Protect the environment by disposing of the
package in compliance with local regulations for
waste processing.
Recycling of obsolete appliances
Equipment containing electrical
components must not be disposed
of along with domestic waste.
It must be separately collected to-
gether with electrical and electronic
waste in accordance with current
local regulations.

PRODUCT PROGRAMME
FTE 400
Thermostat incl. floor sensor
FIG. 1 - INSTALLATION OF THERMOSTAT
The thermostat should be DIN rail mounted.
Connections
Ensure that the main and load cables are con-
nected as shown in the figure.
Term. 1:
Line (L1) 230 V ±10%, 50/60 Hz
Term. 2:
Neutral (L2/N)
Term. 3:
Output for control, max. 100mA
Term. 4–5:
Load, max. 16 A / 3600 W
Term. 6:
Input, night setback (S)*
Term. 7:
Input, frost protection (
Term. 8-9:
External floor sensor (SELV)
Term. 10-11: External room sensor (SELV)
Term. X:
Do not connect
Note: Use a Phillips PH2 or slotted 4x0.8
mm screwdriver. Screws must be tightened
to a torque of 0.5 Nm.
FIG. 1A+1B - NIGHT SETBACK / FROST
PROTECTION
The thermostat has 2 inputs for night setback
and frost protection.
Note: Do not use night setback and frost
protection at the same time.
FIG. 2 - MOUNTING OF SENSORS
You can use the thermostat with external sen-
sors for room and/or floor.
The terminals for the sensor contain a safety
extra-low voltage (SELV) circuit, allowing the
sensor to be placed as close to the floor surface
as necessary without the risk of electric shock,
should the sensor cable become damaged.
Sensor cable recommendations
The following recommendations apply to all
temperature sensor cables:
The sensor cable may be extended with ad-
ditional two-core cable (max. sensor extension,
see technical specification).
The two wires from the sensor to the thermostat
must be kept separate from high voltage wires/
cables.
Place the sensor cable in a separate conduit or
segregate it from power cables in some other
way.
Never use two vacant wires in a multi-core
cable.
Shielded cable does not connect the shield to
earth (PE).
Mounting of external floor sensor
The floor sensor is used for comfort tempera-
ture regulation in rooms on the basis of floor
temperature.
Insert the cable and sensor into a non-conduc-
tive conduit embedded in the floor.
The end of the conduit must be sealed and
the conduit placed as high as possible in the
concrete layer.
The floor sensor must be centred between
loops of heating cable.
FIG. 3 - MOUNTING OF EXTERNAL ROOM
SENSOR
The room sensor is used for comfort tempera-
ture regulation in rooms based of the room
temperature.
The thermostat must be mounted on the wall
approx. 1.4 - 1.6 m above the floor in such
a way as to allow free air circulation around
it. Draughts and direct sunlight or other heat
sources must be avoided.
OPERATING THE THERMOSTAT
To turn on the thermostat, push the power slide
button up to On "I". The backlit display will
briefly show the application and then the set
temperature.
