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.

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.

Garanzia legale

Avviso armonizzato UE sulla garanzia legale

Garanzia legale minima di due anni per i beni venduti nell'Unione europea.

I consumatori possono far valere i loro diritti nell'ambito della garanzia legale di conformità, ad esempio se i beni:

  • non corrispondono alla descrizione;
  • non funzionano come previsto.

I venditori sono responsabili di qualsiasi difetto di conformità esistente al momento della consegna dei beni e che si manifesta entro il periodo della garanzia legale. In tal caso i venditori sono tenuti a offrire:

  • la riparazione o sostituzione gratuita;
  • in alcuni casi, una riduzione del prezzo o il rimborso integrale.

Alcuni paesi prevedono un periodo di garanzia legale più lungo. Per i beni di seconda mano può valere un periodo più breve, ma non inferiore a un anno.

Cosa fare se si ricevono beni non conformi:

  1. contattare quanto prima il venditore per segnalare il problema;
  2. fornire la prova dell'acquisto, ad esempio una ricevuta, una fattura o un estratto conto bancario.

I venditori e i produttori possono anche offrire garanzie commerciali, che si applicano indipendentemente dalla garanzia legale. Ad esempio, questa etichetta GARAN rappresenta una garanzia commerciale di durabilità offerta dal produttore senza costi aggiuntivi, che copre il bene nel suo complesso.
