The Sinclair Keyon in its 3.2 kW version is the set SIH-12BIK2 with the outdoor unit SOH-12BIK2. The manufacturer characterises the series as simple, with a clean white look and functions useful every day: quiet operation, an I FEEL arrangement for more comfortable temperature control, and an 8 °C hold mode that protects a room from chilling. Wi-Fi is standard on this model, and the manufacturer's equipment list names a Wi-Fi module and the YAP1F7 remote controller with Wi-Fi support. The data we use comes from the published product card, and anything the manufacturer does not declare we leave out.
This is an air conditioner with somewhat lower capacity than popular models of higher capacity, and that is exactly its advantage for flats where cooling a small or medium room is enough. Cooling capacity is 3.2 kW (from 0.9 to 3.7 kW), heating capacity 3.4 kW (from 0.9 to 4.1 kW), and the energy classes are A++ in cooling and A+ in heating (SEER 6.5, SCOP 4.1). The low lower limit of 0.9 kW allows the temperature to be held in a small room without constant changes of compressor speed. For the customer it means that the choice between this set and a stronger model should rest on the size and sunlight of the room and not on the price of the unit alone.
On top of this the manufacturer adds a cold plasma generator, that is an ioniser meant to improve the freshness of the air in the room, and a dual-side condensate outlet that lets you route the drain to the right or the left. The indoor unit is 849 mm wide, 289 mm high and 215 mm deep and weighs 10.5 kg. Operation is possible from -15 to 43 °C in cooling and from -15 to 24 °C in heating. The maximum installation length is 20 m.
Overview and positioning
For us the Keyon is a model from the sensible-choice category. It does not try to be the quietest, the most efficient or the most advanced; instead it offers the set of functions that usually suffices in a flat: Wi-Fi, the I FEEL function, the 8 °C mode, a hidden display and a cold plasma generator. The manufacturer itself describes the series as a solution for those who value simplicity, a clean look and maximum functionality without unnecessary compromises. For someone buying a first air conditioner such a list is easy to read: it is clear what you pay for, and you do not have to analyse a dozen modes of which most would never be used.
It is worth noting the capacity: 3.2 kW is a nominal value, lower than many popular sets. For a room of small volume, a bedroom or a child's room this may be exactly the size that does not overdo the power. Before we settle on 3.2 kW we check, during the assessment, the height of the room, the size of the windows and their orientation to the compass points, because these affect the demand for cooling most. An air conditioner that is too big for a small room often runs at the lowest speeds and switches off cyclically, which serves neither comfort nor the durability of the appliance.
The set SIH-12BIK2 / SOH-12BIK2 comes from the Sinclair range, which covers both air conditioners and heat pumps. The data on which we base the description comes from the published product card. This approach makes it easier to compare models, because each one is described by the same criteria: capacity, efficiency, noise, dimensions and functions.
Cooling and heating technology
The system runs on R32 refrigerant and, according to the values given by the manufacturer, delivers cooling of 3.2 kW and heating of 3.4 kW. The capacity ranges are 0.9 to 3.7 kW and 0.9 to 4.1 kW respectively. The wide range means that the unit adapts to the load, and in a small room it can work at very low power, using little energy. Keep in mind that nominal capacity is a reference value, while real operation changes through the day with the temperature outside and in the room. At steady, low power the compressor uses less energy than with frequent starts and stops, and the room temperature is more stable.
Seasonal efficiency is SEER 6.5 in cooling and SCOP 4.1 in heating, which gives classes A++ and A+. These are not record values, but for an air conditioner used mainly in summer and in shoulder seasons they offer a balanced compromise between the price of the unit and its running costs. If you plan intensive all-year use, it is worth comparing this model with units with higher indicators. If the unit is to run a few hours a day all year round, the difference in bills between this and a more efficient model may be noticeable, so we present it in the conversation with the customer instead of leaving it out.
The outdoor unit works in cooling from -15 to 43 °C and in heating from -15 to 24 °C. The tempering mode, that is holding 8 °C, protects the room from excessive chilling while the household is away. In winter the air conditioner supplements heating, but in hard frost its output is limited and it should not be treated as the only source of heat. At the lower heating limit of -15 °C you should expect the unit to deliver less warmth on the coldest days than the nominal capacity suggests.
Comfort and air quality
The manufacturer describes the I FEEL function as a way to regulate temperature more comfortably. In air conditioners such a function usually consists in measuring the temperature where the remote controller lies, and not only next to the indoor unit. This is useful when the unit hangs under the ceiling and you sit at a desk or lie in bed a few metres away, where the temperature can be different.
The cold plasma generator looks after the air. The manufacturer calls it an ioniser and links it with high quality and freshness of the air in the room. It is not a filter or an air purifier, and it does not replace cleaning the air conditioner's elements, but it is an extra feature for people who care about a cleaner atmosphere in the bedroom. Compared with mechanical filters the ioniser is only an addition, so regular cleaning of the filter mesh remains the basis, and dust in the flat has to be handled the traditional way, with a vacuum cleaner and a damp cloth.
The indoor unit runs at between 23 and 41 dB and the outdoor unit at 52 dB. These are sound pressure values, from the quietest to the loudest speed. On the lowest speed the unit is suitable for a bedroom, while on the highest it is clearly audible, which is typical for air conditioners in this class. In practice most of the running time falls on the lower speeds. If the bedroom borders a street or a courtyard, we decide on the position of the outdoor unit together with you already at the assessment, so that noise does not reach the window.
Controls and Wi-Fi
The manufacturer lists a Wi-Fi module and the YAP1F7 remote with Wi-Fi support as part of this set, so unlike some models you do not need to buy an adapter separately. The app lets you control the air conditioner from outside the home, which is convenient when you want to cool the flat before coming back, or check whether the unit was switched on too early. A remote with Wi-Fi support means that the app and local control complement each other and do not exclude each other. We set up the network at commissioning so that the app works from the first day and nobody has to look for the router password during the installation.
A hidden display means that the information on the indoor unit does not glow at night, so in a bedroom neither an indicator light nor the digits showing the temperature disturb you. It is a small but appreciated feature, especially for people sensitive to light during sleep. In a flat with a single bedroom it is one of those details that stop being noticeable after a few nights, but the lack of which can irritate with a first air conditioner that has an illuminated display.
The I FEEL function and the 8 °C mode complete everyday operation. The first is meant to make temperature control more comfortable, the second protects the room from chilling. The whole operation is simple and does not require going through extensive menus, which fits the concept of the series.
Design and build
The manufacturer describes the Keyon as a unit with a simple, clean and minimalist look in white, which blends easily into any interior and does not catch the eye. The indoor unit is 849 mm wide, 289 mm high and 215 mm deep, and its weight is 10.5 kg. It is therefore heavier than some models of similar capacity, which should be taken into account when assessing the wall. On plasterboard walls we check the method of fixing, and on brick or concrete walls we prepare suitable anchors so that the installation is stable.
The dual-side condensate outlet, that is the option of routing the drain to the right or the left, eases installation in flats where the layout of walls or the position of water risers dictates the direction of the drain. The hidden display and the uniform casing make the unit look calm in a bedroom as well.
The set runs on R32 refrigerant, which the manufacturer associates with less environmental impact. The maximum installation length is 20 m, so in an ordinary flat it usually does not form a limit; we check it on site all the same. The outdoor unit needs space on a balcony, facade or bracket, and we agree the details after viewing the place of installation.
Installation and service
We begin the work with a free assessment, during which we set the position of the units and the route of the installation. We quote the installed price after a free assessment. As standard we mount the indoor and outdoor units, run up to several metres of refrigerant, electrical and condensate lines and make the wall penetration, taking care of a tidy arrangement of the cables. We write down the scope of work, so that everyone knows the same assumptions on installation day.
Then we pull a vacuum, check the tightness of the system, charge it with refrigerant and start the air conditioner. We check the operating parameters, configure the controls together with the Wi-Fi module, explain the operation and hand over the warranty documents. After starting we show how to clean the filters and give an approximate date of the first service.
Before the job we discuss possible extra charges: a longer run, drilling through concrete or reinforced concrete, wall chasing, a condensate pump and work from a lift platform. After installation regular filter cleaning and periodic servicing are necessary. The cold plasma generator does not remove the need for those tasks. With several units in one building it also helps to mark which outdoor unit serves which room, which makes later service easier.
Who this model is for — summary
The Sinclair Keyon 3.2 kW is a proposal for a person who wants a simple air conditioner with standard Wi-Fi, without elaborate sensors and a long list of modes. It will do in a smaller bedroom, a child's room or a study, where calm operation, a hidden display and a comfortable temperature where you actually stay count the most. For people looking for quiet and simplicity rather than record parameters, it is a convenient starting point.
If, however, you are looking for the highest efficiency, the quietest operation or stronger heating, consider other models from our catalogue. The Keyon has classes A++ and A+, and its heating capacity is 3.4 kW, so as support for heating it is rather a supplement than a main source of warmth. If you want to compare it with a stronger model, we will prepare a comparison of the manufacturers' figures in one table.
We quote the installed price after a free assessment. During the visit we will look at the room, check the installation route and match the capacity to real conditions. Every model in the catalogue is quoted on the same rules, so a comparison of several of them gives an honest picture of the differences.
