If it is not installed properly, you risk severe damage to property, e.g. by fire. You face
the risk of personal liability for personal injury and material damage.
Always consult an electrician!
*) Technical knowledge required to perform the installation:
The following specialist knowledge is required for installation in particular:
• The ‘Five safety rules’: Disconnect from the mains; secure against reactivation;
ensure dead; 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 classes
• Installation of electrical installation materials
• Type of power supply (TN system, IT system, TT system) and the corresponding
connection criteria (classic earthing, protective earthing, requisite additional
measures etc.)
If you are not a professional, do not do it yourself, always have it carried out by
a specialist.
Further warnings:
• The design of the product corresponds to protection class II (double or reinforced
isolation). Ensure that the insulation of the housing is neither damaged nor
destroyed.
• During installation, all poles must be disconnected from the mains voltage, e.g. via
a RCD. There must be an appropriately dimensioned fuse or circuit breaker
between the RCD and the product.
• The device must be dead during installation and connection. Furthermore, turn
off the automatic circuit breaker and the RCD to disconnect all poles from the
mains voltage. Secure it against unauthorised reconnection, e.g. with a warning
sign. Check to make sure there is no voltage with a suitable measuring instrument
(e.g. a digital multimeter).
• Never connect the product to the power supply immediately after it has been
transferred from a cold environment into a warm environment (e.g. during
transport). The condensation that forms might destroy the device. Moreover, there
is risk of electric shock!
• Allow the product to reach room temperature. Wait until the condensation
has evaporated. In some cases, this may take several hours. Only once the
condensation has evaporated should it be installed, connected to the power
supply and put into use.
c) Protection class
• The product or its housing has protection class IP20 and is suitable for operation
in dry rooms and indoor use only.
• There is no protection against water, combustible gases or vapours.

also operated via the mains power supply can then be connected to the product and switched
on or off by regulating the temperature.
It is equipped with an internal and external sensor (probe). The external sensor can be used to
measure the temperature at a different location to the thermostat, such as on the floor with an
electric floor heating system.
Button lock can be activated to protect against incorrect operation and the product is equipped
with memory storage to preserve data in case of power failure.
The product has protection class IP20 and is suitable for dry rooms and indoor use only.
Do not use it outdoors. Contact with moisture, e.g. in bathrooms, must be avoided under all
circumstances.
For safety and approval purposes, do not rebuild and/or modify this product. If you use
