The Ariston Alys C in the version marked ALYS R32 C 35 MUD0 is a wall-mounted split air conditioner that the manufacturer offers in four outputs. This version has a nominal cooling output of 3.4 kW, with an operating range from 1.1 to 4.1 kW, and a heating output of 3.7 kW, ranging from 1.1 to 4.2 kW. Note how the output is written: the variant name speaks of 3.5 kW, but the manufacturer's table is the basis, so in this description we use 3.4 kW for cooling. The refrigerant is R32 and the maximum installation length is 25 m. For a Warsaw customer the key point is that the manufacturer describes everyday conveniences rather than record-breaking parameters, so judging the model comes down to whether such details matter to you.
Compared with simpler wall units, the Alys stands out through several concrete solutions from the manufacturer's description. The remote has a temperature sensor, so the air conditioner can follow the real temperature where the remote lies. In heating mode the unit is not supposed to blow cold air at the start, and the settings, meaning fan speed, temperature and mode, can be saved and restored. There is also a leak sensor that warns and blocks operation, plus an anti-odour and anti-pollen filter. The outdoor operating range covers cooling from -15 to 50°C and heating from -15 to 30°C. This set of features makes the most sense in a room with an unusual layout, where the spot by the wall with the air conditioner is not where you usually sit.
The indoor unit is white, low and light: it is 194 mm high, 805 mm wide, 285 mm deep and weighs 7.6 kg. The sound pressure level runs from 21 to 40.5 dB depending on the speed. The manufacturer describes control from a phone as possible after adding a dedicated accessory, so we do not assume it in the basic set. This description relies on manufacturer data. Whether the model suits your flat is something we check during a free assessment, and we quote the installed price after a free assessment.
Overview and positioning
The Alys C is a practical wall-mounted Ariston series: the manufacturer stresses the R32 refrigerant, the anti-odour and anti-pollen filter, the leak sensor and quiet running. The description has no slogans about a designer casing or an extensive set of occupancy sensors. That angle suits us, because it lets us say plainly that this is a unit for a person who wants a typical flat air conditioner and values calm airflow, simple operation and a few sensible safeguards. A good test question that we ask customers is whether you mainly want to cool a room in heatwaves and top up the heat outside the season, or you are looking for a full control centre for the home. In the first case the Alys C is a sensible starting point.
In the manufacturer's range the Alys comes in four outputs, and in our catalogue we describe the 35 column. For a living room or a large bedroom in a Warsaw block it is a typical size. The materials we analyse say nothing about specific applications, so we always match the output to floor area, sun exposure and the number of people during the assessment, not from the table alone.
A strength of this series is that the manufacturer clearly describes convenience functions: automatic selection of fan speed and mode depending on air temperature, memory of the settings, and no cold draught at the start of heating. These are small things, but everyday impressions of using the unit are made of them. For families where several people with different preferences share one unit, remembering the settings and a simple remote often mean more than an elaborate menu.
Cooling and heating technology
Cooling output is nominally 3.4 kW and can vary from 1.1 to 4.1 kW. In heating the nominal 3.7 kW varies from 1.1 to 4.2 kW. The lower modulation threshold, about 1.1 kW, lets the unit run calmly when the room has reached the set temperature instead of switching off and on. Seasonal efficiency is SEER 6.1 in cooling and SCOP 4.0 in heating. We do not quote energy classes, because the labels on the manufacturer's page do not match these values; the unit's energy label is what counts. A compressor with such a power range does not have to run flat out most of the time; once the target temperature is reached it drops to lower values. We give no figures for power or current consumption here, because they are not part of the data set on which we base the description.
The outdoor temperature range is from -15 to 30°C for heating and from -15 to 50°C for cooling. The heating range reaches 30°C, so the unit can top up the interior even on a warm spring day. The lower limit of -15°C means the air conditioner works through Warsaw frosts, but in hard frost its heating output falls, so we do not treat it as the only source of heat. In spring and autumn, when it is a few or a dozen degrees outside, such supplementary heating can be more convenient than switching on the heating of the whole building, provided that one unit serves just one room.
The manufacturer states that when heating is switched on the unit does not blow cold air at the start. For the user that is a concrete benefit on a chilly morning. The R32 refrigerant is standard in new splits, and the pipework between the units can be up to 25 m. We always measure the actual route on site.
Comfort and air quality
The most characteristic point is the remote. According to the manufacturer, the operation of the air conditioner depends on a sensor in the remote that detects the actual ambient temperature where the remote is. In practice, if you put the remote on a table by the sofa, the unit will aim for the set temperature exactly there, not under the ceiling by the wall where it is warm. That helps especially in tall rooms and living rooms with a mezzanine, because warm air gathers under the ceiling and a sensor fitted in the unit would read a higher temperature than the one in which you actually sit.
The second area is air hygiene. The Alys has an anti-odour and anti-pollen filter which, according to the manufacturer, eliminates bacteria and thereby limits the causes of allergies. We treat this as an item of equipment, not a guaranteed effect: the filter has to be cleaned according to the manual, because a clogged one stops doing its job. In addition the unit automatically chooses fan speed and mode according to air temperature, so there is no need to keep switching speeds by hand.
The sound pressure level of the indoor unit lies between 21 and 40.5 dB. The lowest value is quiet mode and it is the one that matters in a bedroom. The manufacturer calls the model super quiet; we leave the judgement of that opinion to the user, because 40.5 dB on the highest speed is already clearly audible. For the outdoor unit we have no sound pressure level in the data, so we do not state one. When choosing the night mode, test the lowest speed at commissioning and check whether the 21 dB level is audible at all in your bedroom.
Controls and Wi-Fi
Basic operation is from the remote, which also serves as a temperature sensor. The manufacturer describes that the air conditioner can save the current settings, that is fan speed, temperature and operating mode, and then restore them. Thanks to this you do not have to select your preferred parameters again after coming home, which is appreciated especially by household members sharing one unit. The memory function is also useful in flats let for short periods, where successive tenants return to proven settings with a single button.
Wi-Fi here is an option. The manufacturer writes about Wi-Fi control through a dedicated accessory, which means the module has to be bought separately. We do not claim that it is in the set, and we do not describe an app, because the materials do not name one. If remote control matters to you, say so before ordering and we will check the availability of the accessory for this set. The price of the accessory and its availability depend on the distributor's offer, which is why we give no amounts here.
During commissioning we set up the remote, show the point of placing it where you spend time and go through saving the settings. If the Wi-Fi accessory was ordered, we help with the first configuration. Without it the air conditioner works fully, and remote control can be added later.
Design and build
The indoor unit is white and low: it is 194 mm high, 805 mm wide and 285 mm deep, and weighs 7.6 kg. A low body fits well above a door, above a window or in a place where little space is left under the ceiling. The low mass eases fitting the bracket, also on plasterboard walls, as long as the wall is properly reinforced, which we assess on site. A further advantage of the low shape is easier fitting into recesses and next to wardrobes, where a depth of 285 mm does not collide with the door frame.
The manufacturer's description does not mention finishes, interchangeable panels or any special styling, so we promise nothing beyond a white, simple shape. That is usually a plus in rented or neutrally decorated flats: the unit does not draw the eye. A white, plain shape is easy to hide in the interior, and if the decor changes you do not have to change the air conditioner. If you want a dark or wooden casing, it is better to look at other series in the catalogue.
An interesting safety element is the leak sensor. According to the manufacturer it warns of a liquid leak and at the same time blocks the air conditioner to avoid damage to the device. This is a solution that protects the equipment, but it does not replace periodic tightness checks by a service technician.
Installation and service
Installing the Alys includes mounting the indoor and outdoor units and running the refrigerant, electrical and condensate lines over a stretch of up to a few metres. We make the wall penetration, route the pipes neatly, evacuate the system and check its tightness, then charge it with refrigerant and start the air conditioner. For the user this means one start-up and one visit after which the unit is ready to work and its operation is clear.
After start-up we verify the operating parameters, configure the controls, show how to use the unit and hand over the warranty documents. We discuss surcharges before work: they may concern a longer route, drilling through concrete or reinforced concrete, chasing channels in the wall, a condensate pump or work from a lift platform. The maximum installation length for this model is 25 m. We set the scope of work during a free assessment and quote the installed price after a free assessment.
In use, what counts is cleaning the anti-odour and anti-pollen filter and a yearly service. For a person with an allergy this matters especially in the pollen season, when the filter collects more dirt. We recommend that allergy sufferers clean the filter more often rather than less, following the manufacturer's manual. We plan the service before the cooling season and, if the unit is meant to supplement heating, also before winter.
Who this model is for — summary
The Ariston Alys C is for a customer who wants a functional, low air conditioner for a room and values concrete details: a temperature sensor in the remote, saved settings, a leak sensor and an anti-odour filter with an anti-pollen function. Its assets are the wide heating range, reaching 30°C outdoors, and the low body, 194 mm high, which fits easily above a door or window. It will work well in a bedroom, a living room and a study, where the quiet night speed of 21 dB and the ability to keep the remote beside you count.
It suits less those who need built-in Wi-Fi: here control from a phone requires a dedicated accessory. Nor is it a model with an occupancy sensor described by the manufacturer or with a separately controlled moving airflow. A SEER of 6.1 is lower than in top-shelf models, so with intensive use it is worth calculating the electricity bill in advance.
