Vitovent 050-D

Viessmann Vitovent 050‑D – Decentralised Residential Ventilation Unit
Compact decentralised ventilation system with heat recovery up to 90%, delivering up to 43 m³/h, designed for easy installation in outer walls for both modernisation and new construction projects.

Features

High‑Efficiency Heat Recovery

Recovers up to 90% of heat from exhaust air Reduces heating energy losses Improves energy efficiency compared to window ventilation

Decentralised Ventilation Concept

Installed directly in the building’s external wall No need for centralized ductwork Ideal for: Renovation projects Apartment buildings Individual room ventilation

Alternating Operation Principle

Operates in pairs for continuous ventilation One unit supplies fresh air while the other extracts stale air Switches direction approximately every 70 seconds Integrated ceramic heat storage element: Stores heat from exhaust air Transfers it to incoming fresh air Ensures constant air exchange and high efficiency

Energy Savings & Moisture Protection

Continuous air exchange reduces indoor humidity Prevents condensation and mould formation Eliminates need for frequent manual window ventilation Supports building fabric protection

Flexible Summer Ventilation

Ventilation mode (without heat recovery) Enables use of cool night air for passive cooling Improves comfort during warm periods

Easy Operation & Control

Control options: Control panel with large buttons Rotary control dial for basic operation Supports multiple operating modes: Eco mode (standard operation) Sleep mode Continuous ventilation mode Holiday mode (low energy moisture protection) Automatic mode with humidity control Adjustable airflow levels

Control / Integrations

Standalone System Operation

Designed for independent operation in individual rooms
Does not require central HVAC system integration
