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.

Suitable Elsner Product Solution

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.

Garantía legal

Aviso armonizado de la UE sobre la garantía legal

Garantía legal mínima de dos años para los bienes vendidos en la Unión Europea.

Los consumidores pueden hacer valer los derechos que les otorga la garantía legal de conformidad, por ejemplo, si los bienes:

  • no coinciden con la descripción;

  • la reparación o sustitución gratuitas;
  • en algunos casos, una reducción del precio o un reembolso total.

Algunos países tienen un período de garantía legal más largo. En el caso de los bienes de segunda mano, dicho período puede ser más corto, pero nunca inferior a un año.

Qué hacer si recibe bienes no conformes:

  1. Póngase en contacto con el vendedor lo antes posible para notificar el problema;
  2. Aporte pruebas de la compra, como un recibo, una factura o un extracto bancario.

Los vendedores y los productores también pueden ofrecer garantías comerciales, que se aplican independientemente de la garantía legal. Por ejemplo, la etiqueta GARAN representa una garantía comercial de durabilidad ofrecida por el productor sin coste adicional y que cubre la totalidad del bien.
