KNX Individual Room Control: 3 Tips for the Heating Season

News of 15 October 2026

Individual Temperature Control for Every Room

As the heating season begins, individual room control is once again coming into focus. Whether for new buildings or modernisation projects, planning a KNX heating control system requires careful coordination of different heating systems, room requirements and components.

We have put together three technical tips on how room controllers, heating systems and actuators work together. We also introduce a suitable Elsner solution for implementing KNX individual room control.

3 Tips for KNX Individual Room Control

Icon Heating
Choose the Right Control Method for the Heating System

Heating systems respond differently to temperature changes. PWM control with a long cycle time may suit slow-response underfloor and wall heating, while two-point control can be suitable for fan-assisted heating systems. The control method should always match the system's characteristics.

Define Operating Modes and Setpoint Temperatures

Different operating modes allow switching between comfort temperatures and reduced heating operation. Important factors include how the room is used, the desired setpoint temperatures and appropriate switching between operating modes.

Coordinate Room Controllers and Heating Actuators

Temperature measurement, control and actuators must work together. When configuring the system in ETS, check in particular that the output control variables are compatible with the heating actuator used and the selected control method.

Cala 101 T KNX sec

The Cala 101 T KNX sec room temperature controller combines temperature measurement, heating and cooling control, and direct operation on the device. The touch buttons allow users to adjust the setpoint temperature, while the glass push-button's LED display shows the current temperature.

The integrated PI controller supports single-stage or two-stage heating and cooling control. The device can also be used as a main controller or an extension unit and incorporate external temperature measurements. KNX Secure ensures encrypted communication within the KNX system.

Garantie légale

Avis harmonisé de l'UE sur la garantie légale

Protection offerte par la garantie légale minimale de deux ans sur des biens vendus dans l'Union européenne.

Les consommateurs peuvent faire valoir leurs droits au titre de la garantie légale de conformité, par exemple si les biens:

  • ne correspondent pas à la description;
  • ne fonctionnent pas comme prévu.

Les vendeurs sont responsables de tout défaut de conformité qui existait au moment de la livraison des biens et qui apparaît pendant la période de garantie légale. Les vendeurs se trouvant dans une telle situation sont tenus de proposer:

  • une réparation gratuite ou un remplacement gratuit;
  • dans certains cas, une réduction de prix ou un remboursement intégral.

Dans certains pays, la période de garantie légale est plus longue. Pour les biens d'occasion, une période plus courte peut s'appliquer, mais elle ne peut être inférieure à un an.

Que faire si vous recevez des biens non conformes:

  1. contactez le vendeur dès que possible pour signaler le problème;
  2. fournissez une preuve d'achat, telle qu'un reçu, une facture ou un relevé bancaire.

Les vendeurs et les producteurs peuvent également offrir des garanties commerciales, qui s'appliquent indépendamment de la garantie légale. Par exemple, il se peut que votre bien affiche ce label GARAN, représentant une garantie commerciale de durabilité offerte par le producteur sans frais supplémentaires et s'appliquant à l'ensemble du bien.

Pour en savoir plus sur vos droits dans un pays donné, consultez la page ci-dessous ou demandez au vendeur. https://europa.eu/youreurope/garanties
