Product Overview & Area of Application
The Vaillant climaVAIR exclusive VAI5-035WN air conditioner is a mono-split air conditioning system for conditioning individual rooms. With 3.5 kW nominal cooling capacity and 3.81 kW nominal heating capacity, the system is suitable for living rooms, bedrooms, offices, holiday homes, weekend houses, and comparable single-room applications.
The unit combines an indoor unit and an outdoor unit into a split system and offers, in addition to cooling mode, heating mode, dehumidification, fan mode, and automatic mode. This makes it a flexible solution for room air conditioning not only on hot summer days but also during the transitional seasons.
Technology & Equipment
The indoor unit of the climaVAIR exclusive series is designed as a wall-mounted unit and operates with modern inverter technology. The unit adapts its output to the actual demand, thereby supporting steady operation without unnecessarily harsh temperature fluctuations.
The equipment includes comfort functions such as Sleep, Timer, Turbo, automatic swing function, dehumidification, and air circulation. High-quality filter technology with active ionization supports pleasant room air, while the outdoor unit operates with the refrigerant R32.
Everyday Benefits
In everyday use, the unit offers a clear combination of cooling, supplementary heating function, and air dehumidification. This is particularly practical in rooms that heat up strongly in summer or that are to be selectively tempered during the transitional seasons.
Operation is convenient via infrared remote control and via the app control provided for the series. Timer, Sleep, Turbo, and swing functions make it easier to adapt to the time of day, usage situation, and desired room climate.
System Integration & Compatibility
The Vaillant VAI5-035WN is designed as a mono-split air conditioning system. The system consists of an indoor unit VAI5-035WNI and an outdoor unit VAI5-035WNO and is intended for air conditioning a single room.
The refrigerant connection between the indoor and outdoor units is made via suitable refrigerant lines. The maximum pipe length is 20 m, the maximum height difference is 15 m. The final design, routing, and commissioning must be checked by a qualified professional.

Installation
As a split air conditioning system, the Vaillant VAI5-035WN requires professional installation of the indoor and outdoor units. This includes secure mounting, refrigerant lines, condensate drainage, electrical connection, and final commissioning.
Refrigerant work, leak testing, evacuation, and commissioning may only be carried out by qualified specialists or a refrigeration contractor. The electrical connection and circuit protection must also be checked and executed by qualified personnel.
Notes
For reliable operation, air inlets and outlets should remain unobstructed, filters should be checked and cleaned regularly, and the condensate drain should be kept functional. The installation location of the outdoor unit must be suitable for air flow, service access, and noise emission.
The performance data serve as technical orientation and do not replace room-specific design. Room size, insulation standard, solar radiation, window areas, usage, and internal heat loads should be considered when selecting.
