Single room energy recovery ventilator Wi-Fi

The WALLER Wi-Fi is a ductless, wall-mounted, single-room energy recovery ventilator designed for spaces such as apartments, offices, hotel rooms or commercial premises.

Thanks to wireless control and a dedicated mobile app, it delivers the convenience that modern users expect. The unit operates in regenerative mode with energy recovery or as a classic supply/exhaust fan, adapting to individual needs.

Key features:

  • Wi-Fi control – a mobile app for full control
  • Heat and humidity recovery via ceramic heat exchanger
  • Quiet and energy-efficient operation thanks to a reversible EC motor
  • Built-in gravity shutter
  • Ductless wall installation
  • Two operating modes: regenerative or ventilation
  • Eligible for subsidies (e.g. the “Clean Air” program)

Versatile applications

WALLER Wi-Fi is suitable for a wide range of interiors from residential homes to hotel rooms, cafés, and office spaces. Its ductless installation makes it ideal for both new and existing buildings, where installing ductwork may not be possible or practical.

Heat and moisture recovery

Operating in regenerative mode, the unit alternates between supplying and extracting air in 75-second cycles. The built-in ceramic heat exchanger enables heat and partial humidity recovery, significantly increasing indoor comfort.

Flexible modes and easy control

The unit can be operated using a mobile app and a remote control. It offers two main operating modes:

  • Regenerative mode - alternating supply and exhaust for efficient heat recovery
  • Ventilation mode - allows the unit to operate independently as either supply or exhaust (requires two devices working synchronously for balanced ventilation)

Optional F7 filter

Maintain effective and hygienic operation of your WALLER 64 single room energy recovery unit with the optional F7 filter.

The F7 filter offers ISO ePM1 ≥ 50% protection for more demanding environments.

FAQ

Below you will find the most frequently asked questions about single room energy recovery ventilators.
1Which decentralised WALLER heat recovery ventilator should I choose for my room?
WALLER single room energy recovery units are used in spaces where a standard central ventilation system with heat recovery cannot be installed.
The choice mainly depends on the room’s specific ventilation needs.

  • For example, you can choose the standard WALLER Wi-Fi model if you require basic ventilation with heat and moisture recovery.

  • A decentralised unit with a CO₂ sensor is suitable for spaces where carbon dioxide levels may increase, such as kitchens or boiler rooms. The single room unit automatically adjusts humidity levels according to the set value.

  • You can also choose a wall-mounted unit with an RH (humidity) sensor for locations where moisture removal is essential, such as basements or bathrooms.
    • 2Can I install WALLER CO₂ and WALLER RH single room ventilators in the same room?
    Yes. Such a combination ensures even better air quality. For example, in a house of around 100 m², the WALLER RH can be installed in the toilet instead of a standard exhaust fan, and the WALLER CO₂ in the living room. This setup provides the most efficient air circulation, maintaining air quality according to the set parameters.
    3What type of heat exchanger is used in WALLER single room units?
    WALLER units feature a ceramic heat exchanger that enables both heat and moisture recovery.
    4Is the Wi-Fi module available in every WALLER unit?
    No. The Wi-Fi module is not available in the WALLER 64. To control a wall-mounted heat recovery unit via a mobile app, you need to choose a unit from the WALLER Wi-Fi series or WALLER Wi-Fi CO₂/RH.
