VIESSMANN Vitovent 050-D
| Type | H20E A43 |
- Energy cost savings through heat recovery
- Reliable moisture protection without having to open the window regularly.
- Simple operation with rotary control or with large buttons
- Ventilation mode for summer night cooling
- Two-step installation with rough and finish kit
- Star wiring
- Twist-proof connections
Completion set for decentralized living space ventilation unit with heat and moisture recovery
Operating principle: operation with change of direction via ceramic heat accumulator. The device is installed directly in the outside wall without an air distribution system using a round wall sleeve (accessory) and is therefore particularly suitable for modernization. The 2-part structure of the wall sleeve and the device enables the wall sleeve to be installed in the outside wall and the device at different times.
Scope of delivery:
- 1 fan unit for wall mounting
- fan
- heat accumulator (ceramic)
- Attractive inner panel made of plastic (ASA), colour: white
- Filters G3
Installation requirement:
- wall sleeve (accessories)
- control panel (accessories)
- Power pack flush-mounted or top-hat rail (accessories)
- Paired arrangement
The minimum and recommended wall thickness varies with the wall sleeve used (accessory).
