Hard-to-reach ventilation units – such as those near the ceiling – can be operated conveniently from the wall using the SIEGENIA ventilation control unit as an external control unit. Suitable for the AEROPLUS WRG wall-mounted ventilator and the AEROMAT VT facade ventilation system, it combines easy operation with useful additional features which facilitate everyday ventilation. Equipped with sensors, in automatic mode it provides an exchange of air as and when required or activates night cooling.

• Ventilation control unit: an external control unit for up to 9 ventilation devices
• Ventilation control sensor: with additional temperature, humidity and CO₂ sensors

The SIEGENIA ventilation control unit enables synchronous control of up to nine ventilation units – perfect for large rooms and open-plan living areas. The control unit specifies the mode of operation and air throughput for the master unit. The master unit in turn provides feedback on status, air quality, etc. Up to eight additional ventilators can be connected to the master unit as secondary units.

The AEROPLUS WRG completely redefines wall-mounted ventilation: supply and exhaust air, combined with the principle of a rotary heat exchanger, in a very compact space. This is innovative ventilation technology with a modern design. It combines powerful air throughput with excellent heat recovery of up to 93 %, whilst delivering outstanding sound absorption and low inherent noise. Whether it's for a new build or for an energy renovation project, the AEROPLUS WRG is the unbeatable alternative to conventional push-pull units.

The ultra-compact design of the miniaturised rotary heat exchanger enables regenerative heat recovery in a compact casing for the first time. Two pressure-stable ventilators ensure a balance of supply and exhaust air without any drop in performance, even when there is high wind pressure on the facade. It is also possible to operate the system using supply or exhaust air only, by switching off the relevant ventilator – for intelligent bathroom control, for example. And temporarily deactivating the heat recovery function means that passive cooling is even possible in summer.

The AEROPAC wall-mounted ventilator has been employed well over 100,000 times as a solution to rising noise and environmental pollution. With its sound absorbing fresh air supply, it supports a calm and healthy indoor environment. AEROPAC possesses a powerful fan that is as quiet as a whisper, making its use in larger rooms possible. The multi-stage air throughput can be conveniently regulated and programmed via the LCD display, or also leisurely via an app in the "smart" version. Three optional filters provide effective protection against pollen, fine dust and further environmental pollutants. In contrast, the AEROPAC DD, as a passive ventilator, uses only the natural pressure differential for a demand-based ventilation.

Completely new possibilities are provided by the integration of SIEGENIA window vents in modern roller shutter housings. Because in order to have quiet and well-protected ventilation day and night, the fresh air supply even functions when the roller shutters are down. A benefit that is also combined with improved sound absorption values and a clean appearance in the external facade with no visible weather grille.

Quickly and easily combined: the AEROMAT midi, AEROMAT midi HY, AEROMAT 80 and AEROMAT 100 window ventilators can be flexibly combined with a wide range of roller shutter boxes from leading manufacturers. This applies, for example, for the systems from HELLA, ROMA, Beck+Heun, heroal, profine, LEHR and BERO

Humidity management is achieved using natural air-handling ceilings made up of HUMID modules from ArgillaTherm, a specialist in environmentally friendly air-conditioning systems and products. Thanks to the hygroscopic material used, these virtually carbon-neutral modules are capable of absorbing a high level of moisture in a short space of time, which they then release as soon as there is no longer a need for cooling. The system is sustainable, ensures healthy heating and cooling of indoor spaces that is also suitable for allergy sufferers and asthmatics, and protects the fabric of the building. Decentralised ventilation units from SIEGENIA – such as the AEROMAT VT WRG facade ventilator or the AEROPLUS WRG wall-mounted ventilator – ensure that CO2 is removed and ventilation is tailored to requirements. In addition to ventilation, they offer a number of additional functions such as heat recovery and sound absorption as well as filter functions and sensors for healthy living.

The combination of ArgillaTherm natural air-handling ceilings with decentralised ventilation units from SIEGENIA reduces investment costs by up to 30 percent and operating and maintenance costs by more than 60 percent when compared to conventional solutions. It also has the added benefit of significantly reduced planning costs, installation of the ventilation technology without the need for specialist companies and exemption from mandatory inspections for fire dampers, for example. Funding opportunities can also be maximised in this way.
