Why BX8 KNX?

In office complexes with glass façades, sun protection is crucial for lighting comfort and energy consumption. BX8 KNX enables adaptive control that automatically ensures glare-free working depending on the position of the sun and brightness, while reducing heating and air conditioning costs.

Smart Shading with KNX

Energy efficiency is a must – not an option: Since the German GEG amendment 2023, significantly stricter limits for primary energy consumption have applied to new buildings. Without smart building automation, it is almost impossible to combine comfort, efficiency and legal compliance. Smart systems such as KNX control heating, cooling and sun protection as required – fully automatically and reliably.

Legal guarantee

Harmonised EU legal guarantee notice

Minimum two-year legal guarantee protection for goods sold in the European Union.

Consumers can claim their rights under the legal guarantee of conformity, for example if goods:

  • do not match the description;
  • do not function as intended.

Sellers are liable for any lack of conformity which existed when the goods were delivered, and which becomes apparent within the legal guarantee period. Sellers in such a situation are required to offer:

  • free repair or free replacement;
  • in some cases, a price reduction or full reimbursement.

Some countries have a longer legal guarantee period. For second-hand goods, a shorter period may apply, but not less than one year.

What to do if you receive non-conforming goods:

  1. Contact the seller as soon as possible to report the issue;
  2. Provide proof of purchase, such as a receipt, invoice, or bank statement.

Sellers and producers may also offer commercial guarantees, which apply independently from the legal guarantee. For example, you may see this GARAN label representing a commercial guarantee of durability offered by the producer at no additional cost and covering the entire good.

For more information on your rights in a specific country, visit the page below or ask the seller. https://europa.eu/youreurope/guarantees
