JESSP decentralized residential ventilation with heat recovery, F7 filter and Wi-Fi
The JESSP Eco Smart ventilation unit is a modern decentralized residential ventilation system with heat recovery and smart controls. It improves indoor air quality, helps reduce heating costs and can be controlled flexibly via Wi-Fi, app or optional CO₂ and humidity sensors. With Alexa voice control and compatible Wi-Fi control panels, the ventilation system integrates easily into your smart home.
Airflow explained clearly
- 25 m³/h of fresh air per unit in heat-recovery mode
- 50 m³/h with two synchronized units operating as a pair
- Up to 50 m³/h per unit in supply-only or extract-only mode
- 60 m³/h in boost mode
In heat-recovery mode, the unit alternates regularly between supply and extract air. The average fresh-air volume flow is therefore the relevant value for ventilation planning.
The JESSP Eco Smart ventilation unit is an energy-efficient, smart solution for effective residential ventilation. Its versatile control options provide excellent comfort and individually adjustable indoor air quality.

Noticeably better indoor air quality
Smart residential ventilation
Motorisierte Verschlussklappe
Die automatische Verschlussklappe öffnet und schließt zuverlässig je nach Betriebszustand – für kontrollierten Luftstrom und Schutz vor Zugluft.
Wärme-rückgewinnung
Der integrierte keramische Wärmetauscher nutzt die Wärme der Abluft, um die einströmende Frischluft effizient vorzuwärmen. So bleiben bis zu 97 % der Energie im Raum erhalten, während kontinuierlich frische Luft zugeführt wird.
Das System arbeitet im Wechselbetrieb und sorgt für eine optimale Balance zwischen Energieeffizienz und Luftqualität – ideal für moderne, energieeffiziente Gebäude.
F7 Filter
Das mehrstufige Filtersystem mit integriertem F7-Filter entfernt zuverlässig Feinstaub, Pollen und andere Schadstoffe aus der Außenluft. Gleichzeitig schützt der Vorfilter die inneren Komponenten und verlängert die Lebensdauer des Systems.
Das Ergebnis ist spürbar sauberere, gesündere Raumluft – besonders wichtig für Allergiker und in städtischen Umgebungen.
App Steuerung
Mit der integrierten WLAN-Funktion steuerst du deine Lüftung ganz einfach per App – jederzeit und von überall. Passe Einstellungen an, überwache Luftwerte in Echtzeit oder erstelle individuelle Zeitpläne.
Dank smarter Funktionen wie CO₂- oder Feuchtigkeitssteuerung arbeitet das System weitgehend autonom und sorgt konstant für ein optimales Raumklima.

FAQs
What is a decentralized ventilation system?
A decentralized ventilation system continuously exchanges air in individual rooms without a complex duct network. Stale, humid air is extracted and filtered fresh air is supplied. Heat recovery retains most of the room heat, so you ventilate efficiently without constantly opening windows.
How does heat recovery work?
A ceramic heat exchanger stores heat from the outgoing air. Every 75 seconds the airflow reverses, and the incoming fresh air absorbs the stored heat. This enables up to 97% heat recovery.
Do I need a professional installer?
The unit is ready to plug in and does not require complex ductwork. Installation requires a Ø170 mm core hole through an external wall with a thickness of 280–470 mm. Most customers have the drilling done by a specialist if they do not have suitable equipment.
~ Eco Smart DZ
Does it work in older buildings?
Yes. It is ideal for retrofitting individual rooms without opening walls or ceilings for ducts. A suitable external wall is required for the core hole.
Does decentralized ventilation help prevent mould and humidity?
Yes. Controlled, continuous air exchange removes excess moisture, lowers humidity and helps prevent mould on walls and windows, even in rooms that are difficult to ventilate naturally.
How loud is the system?
Depending on the operating level, the system runs at approximately 19–32.7 dB(A). At the lowest setting it is suitable for quiet nighttime use in bedrooms.
How much electricity does it use?
Only 6–7.8 watts depending on the level. The unit is rated energy efficiency class A and is designed for continuous operation.
Can I control it by app or voice?
Yes. The Tuya Smart or Smart Life app controls ventilation level, mode and filter status over Wi-Fi. Amazon Alexa and Google Assistant are also supported. A 2.4 GHz Wi-Fi network is required.
How often should the filter be replaced?
A filter alert reminds you every 720 operating hours to check the F7 filter. Do not wash it with water; gently tap or vacuum it and replace it when heavily soiled. Clean the ceramic heat exchanger about four times a year using water without high pressure.
