RF-VM: The radio module that makes ventilation flexible

Our Radio Ventilation Module RF-VM is back – bringing a breath of fresh air to ventilation control. The device wirelessly connects motor-driven ventilation units to the WS1 and WS1000 Building Control Systems, making it especially easy to integrate extract air, recirculation or fresh air systems.

Particularly in retrofit projects, the radio technology stands out for its flexibility and minimal installation effort. Up to eight fan stages can be controlled, including shut-off flaps – for precise, efficient and comfortable room climate control.

The relaunched RF-VM is now available again.

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
