WALLER Wi-Fi recuperator

WALLER Wi-Fi wall-mounted heat recovery unit, ductless connected ventilation

The WALLER Wi-Fi heat recovery unit is a ductless wall-mounted ventilation solution, suitable for individual rooms such as bedrooms, offices, or cafes. It is designed for wall mounting and offers comprehensive ventilation thanks to its reversible fan. In regeneration mode, it recovers heat and humidity from the extracted air to limit energy loss and improve comfort.

This Wi-Fi version adds smart connectivity: the device can be controlled via smartphone, and multiple units can be synchronized to work together. It is suitable for both residential use and tertiary spaces.

Ductless ventilation, simple and efficient

The WALLER Wi-Fi unit is directly wall-mounted and provides ventilation without a duct network. It can operate in:

• regeneration mode: heat and humidity recovery
• ventilation mode: supply or extraction (without energy recovery)

Synchronization and control via smartphone

The integrated Wi-Fi module allows for:

• remote control from a smartphone
• pairing multiple devices for synchronized ventilation
• simplified management of ventilation across multiple rooms

Complete ventilation possible with two units

For complete mechanical ventilation (supply + extraction), it is possible to install two WALLER Wi-Fi units: one for supply and one for extraction. In this mode, ventilation is total but without energy recovery.

Simple control with remote

The device also comes with an intuitive remote control for selecting the operating mode and adjusting ventilation.
