Single Room Energy Recovery Unit WALLER Wi-Fi
WALLER Wi-Fi is a ductless wall-mounted energy recovery unit designed for rooms such as apartments, offices, hotel rooms and service premises. Wireless control and the mobile app provide the convenience expected by modern users. The unit can operate in regenerative energy recovery mode or as a supply or extract fan, adapting to individual needs.
About the product
WALLER Wi-Fi is a decentralised wall-mounted heat recovery ventilator with wireless control, designed for direct wall installation — without the need for ventilation ducts. This makes it suitable for many types of spaces, from single-family homes and apartments to hotel rooms, cafes and offices, and installation is even possible in existing buildings.
This version is distinguished by full management of the unit’s operation via a dedicated mobile application — the user can set a schedule, operating mode and supply/exhaust intensity, and monitor the device status from a smartphone or tablet. Control is also possible using the included remote control.
Heat recovery is achieved through a ceramic heat exchanger which, in regenerative mode — with alternating supply and exhaust in 75-second cycles — recovers heat and partially moisture, improving room comfort. Quiet and energy-efficient operation is provided by the reversible EC motor with an integrated gravity shutter, and the energy class A rating qualifies for the “Clean Air” programme.

Why choose the WALLER Wi-Fi heat recovery ventilator?
Comfortable ventilation at your fingertips
WALLER Wi-Fi enables full management of operating parameters through a dedicated mobile application. The user can set a schedule, operating mode, supply and exhaust intensity, and also monitor the device status — all from a phone or tablet.
Versatility of the wall-mounted heat recovery unit
The decentralised heat recovery ventilator is suitable for many types of spaces: from single-family homes to hotel rooms, cafes and offices. Its installation requires no ductwork, enabling retrofitting even in existing buildings.
Heat and moisture recovery
The unit operates in regenerative mode, alternately supplying and exhausting air in 75-second cycles. The decentralised heat recovery unit features a ceramic heat exchanger enabling recovery of both heat and partial moisture, improving room comfort.
Flexible operating modes and easy control
The unit can be controlled via remote control and operates in two main modes:
- Regeneracyjnym — offering heat recovery through alternating supply/exhaust operation
- Wentylacyjnym — enabling independent operation as supply or exhaust (requires two synchronised units for balanced ventilation)
Opcjonalny filtr F7
Ensure effective and hygienic operation of your WALLER Wi-Fi wall-mounted heat recovery unit with the optional F7 filter. F7 filter with ISO ePM1 ≥50% protection for more demanding spaces.

FAQ
WALLER wall-mounted heat recovery units are used in rooms where conventional centralised heat recovery cannot be installed.
The choice mainly depends on the room's requirements.
- For example, the standard WALLER Wi-Fi model is suitable when basic ventilation with heat and moisture recovery is required.
- A decentralised unit with a CO2 sensor is suitable for rooms where carbon dioxide levels may rise, e.g. boiler rooms. The wall-mounted unit automatically adjusts relative to the set humidity value.
- A wall-mounted unit with an RH (humidity) sensor can also be chosen, e.g. in places where moisture removal is critical, such as basements or bathrooms.
Yes, this combination will deliver even better air quality. For example, in a home of approx. 100 m², WALLER RH can be installed in the bathroom instead of a standard fan, and WALLER CO2 in the living room. This arrangement ensures the most effective air circulation, maintaining air quality relative to the set parameters.
WALLER heat recovery units feature a ceramic heat exchanger enabling both heat and moisture recovery.
No, the Wi-Fi module is not available in the WALLER 64. To control the wall-mounted unit via a mobile application, a unit from the WALLER Wi-Fi or WALLER Wi-Fi CO₂/RH series must be purchased.
