Product detailed description

Vaillant climaVAIR pro VAIB1-065WNI - indoor wall-mounted air conditioning unit

VAIB1-065WNI is an indoor wall-mounted air conditioning unit from the climaVAIR pro / climaVAIR air family by the German manufacturer Vaillant, with a nominal cooling capacity of 7.0 kW and heating capacity of approx. 7.8 kW in air-to-air heat pump mode. The unit is mounted on an interior wall and connected via refrigerant piping to an outdoor (compressor) unit - either in a simple mono-split configuration (1:1, so-called "WN" sets), or as one of several indoor units in a multi-split system with the climaVAIR multi VAM1 outdoor unit.

This particular product is a standalone indoor unit without an outdoor unit and without a remote control in the basic package according to the current distribution specification - suitable for adding to an existing outdoor unit, replacing a damaged indoor unit, or as part of your own multi-split configuration assembled from individual components.

VAIB1-065WNI technical parameters

Note: exact dimensions and weight vary only minimally or not at all between capacity classes sharing the same physical chassis - please verify the binding value for a specific unit on the type plate or in the current Vaillant technical data sheet.

Design and features

The VAIB1-065WNI indoor unit contains a plate heat exchanger, a radial fan with multiple speed levels and an electronically controlled expansion (throttling) valve, which in a multi-split configuration allows independent capacity control relative to other indoor units on the same outdoor unit. Air drawn in from the front/top passes through a washable pre-filter that captures coarser dust and hair - the filter is recommended to be cleaned approximately once a month under normal operation, more frequently in dustier environments.

The self-cleaning program automatically dries the evaporator after the unit is switched off (preventing moisture condensation, which would otherwise be a breeding ground for mould and bacteria), thus reducing unpleasant odour upon the next start-up - a useful feature especially for seasonal use of the air conditioning after a longer period of inactivity.

Typical use

With its 7.0 kW capacity, the VAIB1-065WNI unit is suitable for cooling a large living space, showroom or larger office up to approx. 65-70 m². When choosing the capacity, we recommend considering not only the floor area but also the ceiling height, window orientation, glazing ratio, and heat gains from appliances and occupants - in rooms with large glazed areas facing south/southwest, it is advisable to choose a capacity class higher than what the room area alone would suggest.

Connection - standalone or in a multi-split system

The VAIB1-065WNI unit can be used in two ways: either in a simple mono-split configuration with one climaVAIR pro outdoor unit (typically sold as a complete "WN" set), or as one of several indoor units connected to the multi-split climaVAIR multi VAM1 outdoor unit (available in this category in variants for 2 to 5 indoor units). In a multi-split configuration, it can be combined in the same setup with, for example, a different VAIB1 size class depending on the needs of individual rooms.

Installation and mounting

The indoor unit is fixed to a mounting bracket anchored to the wall, observing the minimum clearances from the ceiling and side walls specified in the installation manual (for service access and correct air circulation). The connection to the outdoor unit consists of a pair of copper refrigerant pipes (liquid and gas lines), a communication/power cable and a condensate drain. We recommend routing the refrigerant piping with minimal bends and insulated along its entire length (see insulated refrigerant piping products 1/4" and 1/2" in this category) to prevent heat loss or condensation on piping routed through heated spaces.

After completing the pipe installation, a pressure test, evacuation of the circuit and opening of the service valves on the outdoor unit follow - these steps, as well as the actual connection of the refrigerant circuit, may only be performed by a company authorized to work with refrigerants (F-gases), as this is a legal requirement related to the handling of regulated substances.

Frequently asked questions

Can the VAIB1-065WNI be purchased without an outdoor unit?

Yes, this product is a standalone indoor unit - suitable for adding to an existing outdoor unit or as part of your own multi-split configuration.

Is a remote control included in the package?

According to the current distribution specification, a remote control may not be automatically included when the indoor unit is sold separately - we recommend verifying the current package contents when ordering, or purchasing a remote control separately.

How large a room is the VAIB1-065WNI suitable for?

Approximately for a large living space, showroom or larger office up to approx. 65-70 m², although the exact capacity also depends on glazing, orientation and heat losses of the specific room.

Can this indoor unit be connected to a multi-port outdoor unit?

Yes, it is compatible with climaVAIR multi VAM1 outdoor units (multi-port multi-split outdoor units) as well as with classic mono-split outdoor units from the climaVAIR pro range.

How often should the filter be cleaned?

We recommend cleaning the washable pre-filter approximately once a month under normal operation, more frequently in dustier environments.

Maintenance and service

In addition to regular pre-filter cleaning, it is recommended to have the condition of the heat exchanger, condensate drainage (especially the free flow of the drain hose, to prevent water leaking from the unit) and the overall condition of the refrigerant circuit professionally inspected once a year (ideally before the summer season). The self-cleaning program after each shutdown reduces the risk of odour and mould formation, but does not replace regular professional maintenance.

Why choose the VAIB1-065WNI

The VAIB1-065WNI indoor unit combines design and quiet operation (noise level from as low as 22 dB(A)) with flexibility of use - the same model works both in a simple mono-split set and as part of a larger multi-split configuration built around the climaVAIR multi outdoor unit. Thanks to the A++ energy class for cooling, it offers lower operating consumption compared to older or less efficient units of the same capacity, and the self-cleaning program simplifies indoor air hygiene maintenance.

Energy class and operating costs

The VAIB1-065WNI indoor unit, combined with the corresponding outdoor unit, achieves energy class A++ for cooling and A+ for heating (according to EU energy labelling for air conditioning equipment). In practice, this means lower electricity consumption for achieving the same cooling/heating effect compared to units of a lower energy class or older on/off systems. At a nominal cooling capacity of 7.0 kW and typical operation during the summer months in Slovakia (roughly hundreds of operating hours per season with moderate usage intensity), actual consumption is typically in the low hundreds of kWh - the exact figure depends on the set temperature, heat losses of the room and duration of operation, so this is only an approximate guideline, not a binding figure.

In heating mode (air-to-air heat pump, 7.8 kW capacity), the VAIB1-065WNI unit is primarily suitable as a supplementary heat source outside the main heating season (spring, autumn, mild winter days) - at very low outdoor temperatures, the efficiency and capacity of any air-to-air heat pump decreases, so in colder regions of Slovakia it is not recommended to rely on it as the sole heating source throughout the entire winter.

Design and interior placement

The VAIB1-065WNI indoor unit is mounted in the upper part of the wall (usually 15-20 cm below the ceiling), taking into account free air flow into the room without obstacles (furniture, curtains) directly below the outlet. When choosing the mounting location, avoid direct airflow onto a spot where people sit or sleep for extended periods, and also choose a position with sufficient distance from heat sources (TV, fireplace) that could distort the reading of the unit's room temperature sensor.

Complete installation sequence

• Selecting and fixing the mounting bracket to the wall, drilling a passage for piping and cabling through the perimeter wall.
• Hanging the indoor unit on the bracket, connecting the refrigerant piping (liquid and gas lines), the communication/power cable and the condensate drain hose.
• Connecting to the outdoor unit, checking the slope of the drain hose (so that condensate flows away freely, not back into the unit).
• Nitrogen pressure test, evacuation of the circuit, opening the service valves on the outdoor unit - to be performed exclusively by a company authorized to work with F-gases.
• First start-up, checking operation in all modes (cooling, heating, ventilation), pairing the remote control, and connecting to Wi-Fi if applicable (for compatible models).

Delivery and packaging

The VAIB1-065WNI indoor unit is delivered in protective cardboard packaging sized to its dimensions (1078 × 333 × 246 mm) and weight (13.5 kg) - due to its dimensions exceeding common parcel locker limits, it is delivered via standard courier service to the delivery address, not to a parcel locker.

Warranty

The VAIB1-065WNI indoor unit is covered by a standard 2-year Vaillant manufacturer's warranty from the date of sale to the end customer, subject to professional installation and commissioning by a company authorized to work with refrigerants. We recommend keeping the proof of purchase together with the installation/commissioning report.

Related products for this indoor unit

For the VAIB1-065WNI indoor unit, you will need a matching outdoor unit - either as part of an existing climaVAIR pro mono-split set, or a new climaVAIR multi VAM1 outdoor unit (available in this category in variants for 2 to 5 ports), as well as insulated refrigerant piping of the appropriate diameters (1/4" and 1/2", also available in this category) and a mounting bracket.

Extended FAQ

What is the difference between this unit and a climaVAIR pro "set"?

A complete set (e.g. "VAIB1-065WN") includes both the outdoor and indoor unit together with a remote control as one package for easy purchase of a mono-split system. This product is only a standalone indoor unit - suitable for adding to an outdoor unit you already own, for replacement, or for assembling your own multi-split combination.

Does the unit also work as a dehumidifier?

The unit has a dedicated dehumidification mode (dry mode), in which it reduces room air humidity with minimal cooling effect - however, it is not a dedicated dehumidifier with its own condensate tank; condensate is drained the same way as in cooling mode, via the drain hose.

Is the VAIB1-065WNI suitable for a bedroom in terms of noise?

The noise level at the lowest fan speed (from 22 dB(A)) is among the quieter operating modes of typical wall-mounted air conditioners and is suitable for bedrooms as well; at full capacity, operation is louder, similar to most comparable units.

Can it be controlled via a mobile app?

Selected models of the VAIB1 range support connection to a home Wi-Fi network and control via a mobile app (remote temperature, mode and schedule setting) - we recommend verifying the availability of this feature for a specific unit in the current technical data sheet, as it may vary depending on the production revision and distribution market.

What does energy class A++ mean in practice when choosing a unit?

The energy class expresses the ratio of delivered cooling/heating capacity to consumed electrical energy (so-called SEER for cooling, SCOP for heating) - class A++ means above-average efficiency within the current air conditioning energy labelling scale, i.e. lower electricity consumption for the same capacity compared to class A or lower.

How do I know whether I need the 7.0 kW capacity or another one from the VAIB1 range?

An approximate guide is the floor area and ceiling height of the room, the number and orientation of windows, heat gains from appliances and the number of occupants - a more precise calculation of the room's heat load (especially for larger glazed areas or atypical layouts) should be prepared by an installation company or air conditioning designer before ordering a specific capacity class.

What is the difference between climaVAIR pro and climaVAIR multi from the perspective of this indoor unit?

The indoor unit VAIB1-065WNI itself is physically the same regardless of whether you connect it to a simple mono-split outdoor unit (climaVAIR pro range, usually sold as a complete set) or to a multi-port multi-split climaVAIR multi VAM1 outdoor unit - the difference lies only in how many other indoor units share the same outdoor unit and how capacity is distributed among them.

Will the unit withstand year-round operation, or only seasonal cooling?

The unit is designed for year-round use - cooling in summer, supplementary heating in air-to-air heat pump mode during transitional periods (spring, autumn) and milder winter days, depending on the weather limits of the specific outdoor unit to which it is connected.
