You will often hear terms like ‘guaranteed compatibility’ and a promise of futureproofing used by KNX community. What however does it mean to you as the building owner or occupier – the person agreeing the work proposed by the integrators who have designed your system? It’s relatively easy to write timescales and deliverables into a project; but less so to provide for “what if?” scenarios 10 or 20 years down the line. Is any guarantee worth the paper it is printed on?

The customer contract is with the integrator, and many of them are small firms without huge assets to pursue. So are they putting their neck on the line when making promises about the performance and longevity if an installation? One big claim and they could lose everything? But KNX stands on its record. KNX integrators know that the risk is infinitesimal – they know they can deliver now and in the future.

The key promises implicit in a KNX system are that:
*   all the devices they install will work together as intended
*   any one device can be replaced or upgraded, without compromising the whole system
*   expanding and reconfiguring the system to accommodate the need to change the way a building is laid out and used will always be possible
*   any new KNX software developments will be backwards compatible – a device that was addressed by the KNX configuration software (ETS) in, say 2000, can be managed just as easily with, say a 2025 software version and beyond. Support never ends.

“Technically, these are not big promises – but they are absolute business fundamentals,” says KNX UK President Iain Gordon. “Only the uniquely collaborative and open ethos of KNX could have created a market with this degree of certainty.

“As KNX approaches its fourth decade, manufacturers and integrators throughout the world are now so heavily invested in the products and skills they are developing, that the KNX guarantee is self-sustaining.  No single player has the power to derail it."
