WALLER Wi-Fi CO₂ Recoverer

WALLER Wi-Fi CO₂ Connected Wall-Mounted Heat Recovery Unit

The WALLER Wi-Fi CO₂ recovery unit is a ductless wall-mounted ventilation system, designed to ventilate individual rooms such as bedrooms, offices, or cafes. It integrates a Wi-Fi module for remote control via smartphone and synchronization of multiple devices.

Thanks to its CO₂ sensor, it automatically adjusts ventilation according to air quality. In regeneration mode, it recovers heat and humidity from extracted air to limit energy losses and improve comfort.

Ductless and Connected Ventilation

The WALLER Wi-Fi CO₂ unit mounts directly to the wall and provides simple ventilation without a duct network. It can operate in:

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

Smart Control and Synchronization

The Wi-Fi module allows:

• control from a smartphone
• synchronization of multiple devices
• automatic ventilation based on CO₂
