• Make sure the polarity is correct when inserting the batteries! Only use batteries of the same type. Drained batteries must be removed from the device immediately. Remove batteries from the device if it is not used for a longer period of time.
  Increased r risk of leakage!

• The device is not a toy! Do not allow children to play with it. Never leave the packaging material lying around unattended. Plastic film and small parts may pose a danger to children.

• Store small cells and batteries which could be swallowed out of the reach of children. Swallowing can result in burns, perforation of the soft tissue and death. Severe burns can occur within 2 hours after swallowing. In the event that a cell or battery is swallowed, seek medical assistance immediately.

• When remotely or automatically controlling a device, it is not always possible to guarantee that commands are actually executed or that the correct device status is displayed in the app and on other Smart Home display devices because of external circumstances. This may lead to material damage and/or personal injury. Therefore, you must ensure to the greatest extent possible that no person is endangered at the time of remote operation or automated control. Please take special care when setting up or adjusting the remote control or when using the automated control and check the desired functionality at regular intervals.

• Do not open up the device. It does not contain any parts to be maintained by the user. If a fault occurs, have the device checked by a specialist.

• We accept no liability for material damage or personal injury which is caused by improper use or failure to observe the safety instructions. In these cases, any guarantee claim becomes void! We accept no liability for consequential damage.

• This device may be used by children from 8 years of age and by persons with reduced physical, sensory or mental capacities, or a lack of experience and knowledge provided these persons are supervised or have been instructed in the safe use of the device, and understand the corresponding risks.

• For safety and approval reasons (CE/UKCA), the device may not be modified, and/or no changes may be made to the device without authorization.

• Any use other than that which is described in the user manual is considered improper and leads to the exclusion of guarantee and liability.

• Do not use the device if it has damage visible from the outside, for example, to the housing, to control or connection elements, or if it has a malfunction. If in doubt, please contact our service team.

• Only operate the device indoors and do not expose it to moisture, vibrations, extreme cold temperatures and mechanical stress.

• Only operate the device in dry and dust-free environments without direct sunlight.

• Only use the device together with original components and recommended products from Bosch partners.

Notes

• The range within buildings can differ significantly from the range in open spaces. In addition to the transmitting power and the receiving properties of the receiver, environmental factors such as humidity, as well as the local structural situation, play an important role.
• The device is only suitable for use in residential environments.
• The device is only intended for private use.
• Please note that room temperature control via the radiator thermostat is designed for a double-pipe pressurized heating system with a flow and return pipe per radiator.
• Use in single-pipe heating systems may result in significant differences from the temperature which is set owing to fluctuations in the flow temperature.
