Vaillant climaVAIR pro VAIB1-050WNO - outdoor unit

Product detailed description

Vaillant climaVAIR pro VAIB1-050WNO – powerful monosplit air conditioning outdoor unit, 5.0 kW

Vaillant climaVAIR pro VAIB1-050WNO is the outdoor unit of the more powerful model of the monosplit wall-mounted air conditioning line climaVAIR pro. It is a product designed for larger rooms and open spaces, sold separately as a complement to the indoor unit VAIB1-050WNI (available in our offer) – typically used when replacing a faulty outdoor unit, completing a system in stages, or when assembling your own combination of components instead of buying a ready-made set. The unit is designed exclusively for monosplit operation (one outdoor unit per one indoor unit); for solutions with multiple air-conditioned rooms from a single compressor, there is a separate climaVAIR multi line with outdoor units of the VAM1 series.

Performance and energy parameters

The VAIB1-050WNO model provides a rated cooling capacity of 5.0 kW and a heating capacity of 5.5 kW. According to the official EU energy label (Regulation 626/2011), the combination VAIB1-050WNO + VAIB1-050WNI has a stated design cooling load (Pdesignc) of 5.3 kW and design heating load (Pdesignh) of 4.2 kW, with a seasonal energy efficiency ratio SEER of 7.3 and a seasonal coefficient of performance SCOP of 4.2 (average climate zone; SCOP 5.7 for warmer and 3.4 for colder climate zones). The cooling energy class is A++, and the heating energy class in the average zone is A. The annual energy consumption for cooling (QCE) is 254 kWh, and for heating (QHE) 1,400 kWh according to the standardized test – actual consumption varies depending on usage patterns and location. The sound power level of the outdoor unit is 65 dB(A).

The refrigerant used in the system is R32 with a charge of approximately 0.85 kg. The operating outdoor temperature range is -15°C to +50°C for cooling and -15°C to +30°C for heating. The outdoor unit dimensions (width × height × depth) are 802 × 555 × 350 mm, i.e. somewhat greater depth and width than the smaller 025/035 models, and the net weight is 34 kg. The maximum length of the refrigerant piping between the outdoor and indoor unit is 15 m, and the maximum height difference between the units is 10 m.

Construction and technology

The outdoor unit is fitted with a more powerful rotary compressor with DC inverter speed control, which continuously adapts output to the current thermal load of a larger room or open space. As a result, the unit doesn't run unnecessarily at maximum output all the time, but only as much as is needed to maintain the set temperature, which saves electricity and reduces compressor wear. A multi-speed axial fan ensures sufficient heat dissipation even at higher summer temperatures and higher thermal loads. The electrical power supply remains single-phase, 220–240 V / 50 Hz, so even with this more powerful model, a three-phase supply is not required for a typical residential installation.

The unit includes an integrated WiFi module for connection to the myVAILLANT Services app, through which the system can be controlled remotely, a weekly operating schedule can be planned, energy consumption can be monitored, and diagnostic alerts can be received. For the larger spaces where this model is typically used (living rooms combined with dining areas, open-space offices, retail spaces), remote control is especially practical for operation without a permanent physical presence of staff during the day.

Installation of the larger unit

Due to the higher weight (34 kg) and larger dimensions, extra attention needs to be paid to the load-bearing capacity of the mounting bracket and wall anchoring when installing this model – we recommend consulting with an installation company regarding the type of anchoring material suitable for the given facade construction (masonry wall, insulated ETICS system, timber structure, etc.). At atria.sk you will find brackets for both insulated and uninsulated facades, as well as rubber feet for free-standing installation on a roof or reinforced floor, which are a suitable alternative especially in cases of uncertain wall load capacity. Sufficient free space must be maintained around the unit for air intake and exhaust (at least 30 cm from side obstacles, approximately 100-150 cm in the direction of the main airflow for this more powerful model) to prevent recirculation of warm air and a drop in efficiency.

Connection to the indoor unit VAIB1-050WNI is made using insulated copper refrigerant piping (available in our offer in diameters from 1/4" to 5/8", in lengths of 10 or 25 m – for this power model, a larger pipe diameter is more commonly used in practice than for the smaller 025/035 models) and an interconnecting cable for power supply and communication. Connection and evacuation of the refrigerant circuit, as well as checking the tightness of the joints, must be carried out exclusively by a person holding a valid F-gas certification.

Recommended use of the 050 model

The manufacturer recommends this model for rooms with an area of approximately 23–34 m², which corresponds to a larger living room combined with a kitchen, an open-plan office for several workstations, a small retail space, or a larger meeting room. The 050 model represents the mid-power category within the climaVAIR pro line and is a suitable choice where the 035 model (16-24 m²) is no longer sufficient, but the most powerful 065 model (27-42 m²) would be unnecessarily oversized. This outdoor unit is typically ordered by:

• installation companies performing a service replacement of a damaged outdoor unit for an existing VAIB1-050WNI,
• investors and developers completing larger construction or renovation projects in stages,
• operators of commercial spaces (offices, shops, medical practices) addressing air conditioning for a larger open space,
• customers dealing with an insurance claim or a warranty/post-warranty replacement of the outdoor unit.

Service and maintenance

For more powerful units such as the 050 model, somewhat more thorough regular maintenance is recommended than for small models, since a larger heat exchanger and higher airflow also mean faster fouling of the fins with dirt during intensive operation. We recommend checking and, if necessary, cleaning the exchanger fins at least once a year before the cooling season, checking the condensate drain function, and verifying the tightness of the mounting on the bracket or feet (especially after a winter period with frost and wind). A professional service inspection checking refrigerant pressure, circuit tightness, and the condition of electrical connections once every 1-2 years is even more important for this power model, since any fault or refrigerant leak will result in a more pronounced drop in performance given the larger charge volume (0.85 kg).

We recommend cleaning the filter of the indoor unit VAIB1-050WNI approximately once every 2-4 weeks under normal operation, and more often in dustier environments (e.g. busy retail spaces). We also offer a replacement antibacterial filter with silver ions, particularly suitable for spaces with higher air quality requirements (medical practices, food shops, spaces with children).

Why choose Vaillant climaVAIR pro for larger spaces

In larger and open spaces, the energy efficiency of air conditioning is even more important than in small rooms, since absolute electricity consumption grows with unit output. The VAIB1-050WNO model achieves above-average SEER 7.3 and SCOP 4.2 values within its class, which brings noticeable savings over the course of year-round operation in both commercial and residential settings compared to older or cheaper equipment. Customers with other Vaillant devices (boilers, heat pumps) will also appreciate the unified myVAILLANT interface for managing all home or facility equipment, including a shared overview of energy consumption and service alerts in one place.

At atria.sk you will find the entire range of the climaVAIR pro and climaVAIR multi lines, including the accessories needed for installing this more powerful model – larger-diameter refrigerant piping, more robust mounting brackets, and replacement filters.

Airflow and comfort features

The climaVAIR pro system in this model offers 3D airflow with 7 fan speeds, which stands out even more with the higher output and larger room area – it ensures even distribution of cooled or heated air into all corners of a larger space without significant temperature differences between individual parts of the room. Automatic self-cleaning of the indoor unit after the cooling cycle prevents moisture buildup in the evaporator and mould formation, which is particularly important in commercial spaces with higher air hygiene requirements. The dehumidification capacity of this model is 1.8 l/h, which is especially beneficial when the room is highly occupied by people (e.g. meeting rooms, retail spaces), when moisture production is higher.

Comparison with other models in the line

In addition to the 050 model, the climaVAIR pro line also offers smaller variants VAIB1-025WNO (2.5/3.2 kW) and VAIB1-035WNO (3.5/3.8 kW) for smaller rooms, and a more powerful VAIB1-065WNO model (7.0/7.8 kW) for large spaces over 27 m². All models are also available separately at atria.sk and share the same R32 refrigerant, DC inverter compressor technology, and WiFi connectivity – they differ mainly in output, physical dimensions and weight of the outdoor unit, noise level, and recommended room area. When choosing the right model, it is advisable to consider not only the floor area but also the ceiling height, window orientation, number of occupants, and the degree of shading of the room.

What to order together with the replacement outdoor unit

Since the product is sold separately, before ordering we recommend verifying whether you already own a compatible indoor unit VAIB1-050WNI, and whether you will also need to purchase refrigerant piping (available in diameters from 1/4" to 5/8", lengths of 10 or 25 m), a mounting bracket with sufficient load capacity, or rubber feet for free-standing installation. The complete range of accessories can be found in the Vaillant air conditioning accessories category directly at atria.sk, allowing you to order everything needed at once and save on shipping.

Use in commercial environments

Thanks to its output, the VAIB1-050WNO model is often installed in commercial environments – small shops, medical practices, open-space offices, or meeting rooms. In these applications, compared to residential installation, the longer daily operating time of the unit must also be taken into account (often 8-12 hours a day on working days), which places higher demands on regular maintenance and servicing, but at the same time means a faster return on investment in a more energy-efficient model with high SEER/SCOP compared to a cheaper, less efficient alternative. In commercial spaces with high footfall (shops, medical practices, waiting rooms), we also recommend more frequent replacement or cleaning of the indoor unit's air filter and consideration of the antibacterial filter with silver ions, available separately in our offer.
