Safety instructions
Read the operating instructions
carefully and especially observe
the safety information. If you do
not follow the safety instructions
and information on proper han-
dling in this manual, we assume
no liability for any resulting per-
sonal injury or damage to prop-
erty. Such cases will invalidate the
warranty/guarantee.
a) General information
• The device is not a toy. Keep it
out of the reach of children and
pets.
• Do not leave packaging mate-
rial lying around carelessly. This

material for children.
• Protect the appliance from ex-
treme temperatures, direct sun-
light, strong jolts, high humid-
ity, moisture, flammable gases,
steam and solvents.
• Do not place the product under
any mechanical stress.
• If it is no longer possible to oper-
ate the product safely, take it out
of operation and protect it from
any accidental use. Safe opera-
tion can no longer be guaran-
teed if the product:
- is visibly damaged,
- is no longer working properly,
- has been stored for extended
periods in poor ambient con-
ditions or
- has been subjected to any
serious transport-related
stresses.
• Please handle the product care-
fully. Jolts, impacts or a fall even
from a low height can damage
the product.
• Consult an expert when in doubt
about the operation, safety or
connection of the appliance.
• If you have questions which
remain unanswered by these
operating instructions, contact
our technical support service or
other technical personnel.
b) Installation / connection
Caution, safety hazard!
The product should only be in-
stalled by people with relevant
electrical knowledge and experi-
ence! *)
If it is not installed properly, you
risk:
• your own life
• the life of user of the electrical
device
If it is not installed properly, you risk
severe damage to property, e.g. by
fire.
You face the risk of personal liabil-
ity for personal injury and material
damage.
Always consult an electrician!
*) Technical knowledge required to perform
the installation:
For the installation, the following specialist
knowledge is required in particular:
• The “Five safety rules”: Disconnect from
the mains; protect against accidental
switch-on; ensure there is no voltage; earth
and short-circuit; cover or protect adjacent
live parts
• Use of suitable tools, measuring devices
and personal protective equipment, where
necessary
• Analysis of measurement results
• Use of electrical installation materials to
meet the requirements for disconnection
• IP protection ratings
• Installation of electrical installation materi-
als
• Type of power supply (TN system, IT
system, TT system) and the correspond-
ing connection criteria (classic earthing,
protective earthing, necessary additional
measures etc.)
If you are not a professional, do not do it your-
self, have it performed by a specialist.
Further warnings:
• The construction of the product corre-
sponds to the protection-class II (double
or reinforced isolation). Ensure that the in-
sulation of the housing is neither damaged
nor destroyed.
• During installation, all poles must be dis-
connected from the mains voltage, e.g., via
RCD. There must be an appropriately rated
fuse or circuit breaker between the RCD
and the product.
• The device must be voltage-free during
installation and connection. Furthermore,
turn off the automatic circuit breaker and
the earth leakage circuit breaker to discon-
nect all the poles from the mains voltage.
Secure it against unauthorised reconnec-
tion, e.g., with a warning sign. Check to
make sure there is no voltage with a suit-
able measuring instrument (e.g., a digital
multimeter).
• Never connect the product to the power
supply immediately after it has been trans-
ferred from a cold room into a warm one
(e.g., during transport). The condensation
that forms might destroy the device. Moreo-
ver, there is danger of electric shock!
• Allow the product to reach room tempera-
ture. Wait until the condensation has evap-
orated. This might take several hours. Only
after this, should it be installed, connected
to the mains supply and put into use.
• Do not use the product in rooms with ad-
verse environmental conditions, where
combustible gases, vapours or dust are
or may be present! There is a danger of
explosion!
c) Ingress protection
• This device has an IP20 ingress protection
rating and is suitable for dry rooms.
• There is protection against touching live
components and ingress from foreign par-
ticles >12.5 mm.
• There is no protection against water, com-
bustible gases, and vapours.
Operating Instructions
Heating Thermostat with WiFi and Sensor
Item No. 2250410
Intended use
The heating thermostat is intended for temperature control in conjunction with an electric heat-
er. The product operates under the mains voltage; a mains operated load can be connected
and switched on or off by temperature control.
It is equipped with an internal and external sensor (probe). The external sensor can be used to
measure the temperature in a different location to the thermostat, such as on the floor with an
electric floor heating system.
A keypad lock can be activated to protect against incorrect operation, and a backup (non-
removable) capacitor supplied with the unit serves to preserve data in case of power failure.
This device has an IP20 ingress protection rating and is suitable for dry rooms and indoor use.
Do not use it outdoors. Contact with moisture, e.g. in bathrooms, must be avoided under all
circumstances.
For safety and approval purposes, you must not rebuild and/or modify this product. If you use
the product for purposes other than those described above, the product may be damaged. In
addition, improper use can result in short circuits, fires, electric shocks or other hazards. Read
the instructions carefully and store them in a safe place. Make this product available to third
parties only together with its operating instructions.
