WALLER Wi-Fi RH Recovery Unit

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

The WALLER Wi-Fi RH recovery unit is a ductless wall-mounted ventilation system, suitable for rooms such as bedrooms, offices, or coffee shops. It includes a Wi-Fi module for smartphone control and synchronizing multiple devices.

Thanks to its relative humidity (RH) sensor, it automatically adjusts ventilation according to the humidity level. In regeneration mode, it recovers heat and humidity from the extracted air to limit energy losses and improve comfort.

Ductless and Connected Ventilation

The WALLER Wi-Fi RH 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 for:

• control from a smartphone
• synchronization of multiple devices
• automatic ventilation according to humidity
