Heat recovery unit WALLER Wi-Fi
WALLER Wi-Fi is a ductless wall-mounted energy recovery unit designed for the ventilation of rooms such as apartments, offices, hotel rooms, or commercial premises. Thanks to wireless control and a mobile app, it offers the convenience that modern users expect. The unit operates in regenerative mode with energy recovery, or as supply or exhaust only — adapting to individual needs.
About the product
WALLER Wi-Fi is a decentralised wall-mounted energy recovery unit with wireless control, designed for direct installation in the wall — without the need to run ventilation ducts. This makes it suitable for many types of rooms, from single-family homes and apartments to hotel rooms, cafés, and offices, and installation is possible even in existing buildings.
What sets this version apart is full management of the unit’s operation from a dedicated mobile app — the user can set the schedule, operating mode, and the intensity of supply and exhaust, as well as monitor the unit’s status from a smartphone or tablet. Control is also possible using a remote control.
Energy recovery is achieved by a ceramic exchanger, which — in regenerative mode, with alternating supply and exhaust in 75-second cycles — recovers heat and, partially, moisture, increasing room comfort. Quiet, energy-efficient operation is ensured by a reversible EC fan with a built-in gravity shutter, and energy class „A” allows the unit to qualify for the „Clean Air” programme.

Why choose the WALLER Wi-Fi heat recovery unit?
Comfortable ventilation within reach of your smartphone
WALLER Wi-Fi enables full management of the operating parameters through a dedicated mobile app. The user can set the schedule, operating mode, and the intensity of supply and exhaust, as well as monitor the unit’s status — all from a phone or tablet.
Versatility of the wall-mounted energy recovery unit
The decentralised energy recovery unit works well in many types of rooms: from single-family homes to hotel rooms, cafés, or offices. Its installation does not require running ducts, which allows it to be installed even in existing buildings.
Energy recovery unit with heat and moisture recovery
The unit operates in regenerative mode, alternately supplying and exhausting air in 75-second cycles. The decentralised energy recovery unit features a ceramic exchanger enabling heat recovery, as well as partial moisture recovery — increasing room comfort.
Flexible operating modes and easy control
The unit can be controlled using a remote control and operate in two main modes:
- Regeneracyjnym — offering heat recovery through alternating supply/exhaust operation
- Wentylacyjnym — enabling independent operation as supply or exhaust (requires two units working synchronously to provide supply-exhaust ventilation)
Optional F7 filter
Ensure the effective and hygienic operation of your WALLER Wi-Fi wall-mounted energy recovery unit with the optional F7 filter. The F7 filter offers an ISO ePM1 ≥50% protection level for more demanding spaces.

WALLER wall-mounted energy recovery units are used in rooms where standard heat recovery cannot be applied..
The choice mainly depends on the requirements of the room.
- For example, you can choose the standard WALLER Wi-Fi model when you need basic ventilation with the possibility of heat and moisture recovery.
- You can choose a decentralised energy recovery unit with a CO2 sensor, which is used in rooms where the carbon dioxide concentration may rise, e.g. in boiler rooms. The wall-mounted energy recovery unit automatically adjusts the humidity level relative to the set value.
- You can also choose a wall-mounted energy recovery unit with an RH (humidity) sensor, e.g. in places where moisture removal is essential, such as basements or bathrooms.
Yes, such a combination will ensure even better air quality. For example, in a home of approximately 100 m², WALLER RH can be installed in the toilet instead of a standard fan, and WALLER CO2 in the living room. Such a setup will ensure the most effective air circulation, maintaining air quality relative to the set parameters.
WALLER energy recovery units feature a ceramic exchanger enabling heat and moisture recovery.
No, a Wi-Fi module is not available in the WALLER 64 energy recovery unit. To control the wall-mounted unit using the app, you need to purchase a wall-mounted energy recovery unit from the WALLER Wi-Fi or WALLER Wi-Fi CO₂/RH series.
