Terms and conditions

KNXExpert is the trading name of Connektik Sarl-S, 21, rue Charles Rausch, L-7247 Helmsange, Luxembourg, available at [email protected] and +352 26 43 02 74.

These terms cover KNX design, ETS programming, commissioning, audits, troubleshooting, documentation, training and related services, together with equipment expressly included in a quote. They apply to electrical contractors and other business clients as well as consumers.

Website information and simulator estimates are indicative. Only a written quote sets out the binding offer, validity period, scope, exclusions, price, payment terms and, where possible, schedule.

The contract is formed when the client accepts the quote in writing or by the acceptance mechanism stated in it. Reservations or different terms require Connektik Sarl-S's written agreement.

The quote allocates responsibilities between KNXExpert, the client, electrician, architect and other contractors. Unless stated otherwise, KNXExpert does not perform power wiring, cabling or building work entrusted to the relevant qualified trades.

The client appoints a contact, supplies accurate plans and information on time, obtains required permissions and provides safe access to the site, equipment and networks needed for the work.

Prices are stated in euros. Consumer prices include all applicable taxes unless a clear lawful statement says otherwise. For business clients, the quote states whether amounts exclude or include VAT.

Milestones, deposits and payment deadlines appear in the quote or invoice. Legally applicable interest and recovery charges may be claimed after late payment, subject to mandatory consumer protections.

A scope change, new function, correction of non-compliant wiring or work caused by incomplete information requires written agreement on the price and schedule impact before it is performed. In an urgent safety situation, the parties first agree the strictly necessary measures.

Dates are based on available information and project dependencies. Unless expressly described as firm, they are estimates. KNXExpert informs the client of a foreseeable delay.

Site unavailability, third-party work, missing equipment, client-requested changes or late information may lead to a reasonable adjustment of the schedule and, where necessary, the agreed price.

At completion, the agreed functions are tested with the client or its representative. Visible reservations should be recorded precisely or reported without unreasonable delay. KNXExpert remedies non-conformities within its agreed scope.

Using the installation without reservation does not remove a consumer's statutory rights.

Deliverables are those listed in the quote. After full payment, the client receives the rights needed to operate and maintain the installation. Delivery of the ETS file, plans, backups, passwords and manuals depends on the agreed scope and should be expressly documented.

KNXExpert's pre-existing methods, libraries, templates and tools remain its property. Third-party software, licences and components remain subject to their publishers' terms.

Where KNXExpert supplies equipment, references and applicable warranties are stated in the quote. Mandatory statutory rights, including a consumer's legal conformity guarantee for goods, remain fully effective.

A fault caused by an item outside the scope, a third-party modification, misuse or a defect in the existing infrastructure may require diagnosis and a separate offer.

Each party is liable for direct, foreseeable loss caused by its breach. KNXExpert is not liable for decisions or work of other contractors or for consequences of inaccurate or incomplete information supplied by the client.

Nothing limits liability for fraud, gross negligence, death or personal injury, or rights that a consumer cannot waive.

Where a contract is concluded at a distance or off premises, a consumer generally has fourteen calendar days to withdraw without giving a reason, subject to statutory exceptions. For a service, the period runs from conclusion; for goods, it generally runs from receipt.

If the consumer expressly asks for performance to start before that period ends and then withdraws, the consumer pays a proportionate amount for work already provided. The right is lost after full performance only where performance began with prior express consent and acknowledgement of that consequence.

Withdrawal may be sent unambiguously to [email protected] or Connektik Sarl-S, 21, rue Charles Rausch, L-7247 Helmsange. KNXExpert refunds amounts due within the statutory deadline.

To Connektik Sarl-S / KNXExpert, 21, rue Charles Rausch, L-7247 Helmsange, [email protected]: I hereby give notice that I withdraw from my contract for the following service.

• Service and quote number:
• Date the contract was concluded:
• Consumer's name and address:
• Date and signature, only when sent on paper:

Complaints should first be sent to [email protected] with the quote or invoice number and a precise description. KNXExpert will seek an amicable solution within a reasonable time.

For a serious breach, the other party may request correction within a reasonable period and then suspend or terminate if the breach continues. Services performed, equipment ordered and costs incurred remain payable to the extent permitted by law.

Neither party is liable for delay or failure caused by an external event that could not reasonably be foreseen or overcome. The affected party promptly informs the other and mitigates the effects. If the impediment continues, the parties seek a solution or end unperformed services.

The contract is governed by Luxembourg law. A consumer is not deprived of mandatory protection in the country of residence or applicable jurisdiction rules. Between businesses, the courts of Luxembourg have jurisdiction unless otherwise agreed in writing or required by mandatory law.

If one clause is invalid, the remaining terms continue to apply. Delay in exercising a right is not a waiver. The applicable version is the one supplied or available when the quote is accepted.
