Shading made easyt: KNX Actuator for Blinds with 2 Lower Limit Switches

News of 4 May 2023

Our KNX actuator for your blinds control

Spring is slowly setting in with the first warmer rays of sunshine. A good time to deal with the topic of shading in the Smart Building.

Are you still looking for a suitable blind control device for your next KNX project?

Then take a look at our revised actuator KNX S4-B12 DES!

The actuator controls motors with double lower limit switches for the lower end position, such as those used for special external venetian blinds. These blinds are positioned via two separate low travel commands: AB1 moves the blind downwards. In doing so, the slats typically remain open and daylight enters even while the blind is moving. AB2 closes the slats when the lower end position is reached. This darkens the room.

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.
