Smart control of our AHUs with KNX
In a world where indoor comfort et energy efficiency are central concerns, the control of Air Handling Units (AHUs) plays a key role.
This equipment manages temperature, humidity, le CO₂, le airflow and pressure, based on multiple probes and sensors. Their role is to ensure air quality, occupant comfort et energy performance.
Why choose KNX for control?
At Depair, our controllers already support various protocols such as Modbus, BACnet ou KNX.
But KNX stands out for several major strengths:
- ✅ An open, interoperable international standard : KNX is recognised by more than 500 manufacturers and guarantees long-term compatibility.
- ✅ Unified data reporting : temperature, humidity, CO₂ and pressure sensors communicate directly on the KNX bus.
- ✅ Interoperability : via gateways, KNX integrates easily into existing BACnet or Modbus environments.
- ✅ Smart scenarios : automatic adjustment of the ventilation airflow according to occupancy, air quality or outdoor conditions.
- ✅ Security & future-proofing : KNX Secure protects communications and prepares buildings for future needs.
Integration example
Imagine a Depair system connected via KNX:
- The sensors measure in real time CO₂, temperature and humidity.
- The KNX controllers transmit this data to the central supervision system.
- The control system automatically adjusts the fans, dampers and valves to maintain optimal comfort.
- Facility managers get clear visualisation andlive alerts to anticipate needs.
The result:
👉 An optimised indoor air quality,
👉 An reduced energy consumption,
👉 An simplified operation for technical operators.
Towards smarter control
With the integration of KNX, Depair takes a new step in the digitalisation of control for AHUs.
We now offer our clients:
- more comfort,
- better efficacité énergétique,
- and full interoperability with their existing systems.
