Product Overview & Area of Application
The Vaillant climaVAIR exclusive VAI5-050WN split air conditioning system 5.3 kW is a mono-split climate set for air conditioning individual rooms. It combines an indoor unit with an outdoor unit and is suitable for living spaces, offices, practices, and suitable smaller commercial areas when permanently installed room climate control with cooling and heating operation is desired.
With 5.3 kW cooling capacity and a confirmed heating function, the unit is designed for flexible use across multiple seasons. The energy efficiency class A++ in cooling mode and A+ in heating mode supports a factual technical classification during product selection.
Technology & Equipment
The VAI5-050WN is designed as a mono-split system and consists of the indoor unit VAI5-050WNI and the outdoor unit VAI5-050WNO. The indoor unit handles room air distribution and operating logic, while the outdoor unit provides the refrigeration circuit with the refrigerant R32.
The system offers cooling operation, heating operation, ventilation, and dehumidification. Additionally, operating functions such as timer, sleep, turbo, X-fan, as well as operation via remote control and app are described for the series. The air distribution can be adjusted vertically and horizontally, allowing the tempered air to be distributed more evenly in the room.
Everyday Benefits
The split air conditioning system enables permanent room climate control without a mobile exhaust air system, making it particularly suitable for rooms where regular cooling or tempering during the transitional period is desired. The combination of cooling, heating, ventilation, and dehumidification offers more flexibility than a pure cooling device.
For daily operation, the remote control, time scheduling, sleep mode, quieter operating mode, and automatic air distribution are particularly practical. The filter and air purification functions of the series additionally support orderly room air management and facilitate regular maintenance.
System Integration & Compatibility
The set is designed as a mono-split air conditioning system for combining one indoor unit with one outdoor unit. The associated components are VAI5-050WNI as the indoor unit and VAI5-050WNO as the outdoor unit.
For integration, refrigerant lines, condensate drainage, electrical supply, and proper placement of indoor and outdoor units must be considered. Line length, height difference, and operating ranges must match the specific installation situation.

Installation
The installation of a split air conditioning system requires professional planning and execution. The indoor and outdoor units must be positioned appropriately, securely fastened, and connected with suitable refrigerant and condensate lines.
Refrigerant work, evacuation, leak testing, and commissioning may only be carried out by qualified specialists or a refrigeration company. The electrical connection must be checked and carried out by qualified personnel.
Notes
The air paths of the indoor and outdoor units must remain clear so that air performance, noise behavior, and operational safety are not impaired. Filters and visible air ducts should be checked and maintained regularly.
The performance data serve as technical orientation and do not replace an object-specific cooling load calculation, electrical planning, or installation planning. In the event of unusual noises, error messages, visible damage, or suspicion of refrigerant leakage, a specialist company must be consulted.
