The Rotenso Teta Mirror 3.5 kW is a wall-mounted split air conditioner with an inverter compressor, designed for cooling and heating flats, houses and offices. Nominal cooling capacity is 3.5 kW (range 1.0 to 4.6 kW) and nominal heating capacity is 3.9 kW (1.0 to 4.9 kW). The refrigerant is R32. The indoor unit combines a matte dark casing with a glass front panel and measures 820 × 195 × 306 mm at a weight of 9 kg.
In cooling the unit reaches a SEER of 8.5 and class A+++, and in heating a SCOP of 4.7 and class A++. The indoor unit works in the range of 18 to 44 dB, and the outdoor unit is rated at 53 dB. The manufacturer states cooling operation at outdoor temperatures from -15 to 53 °C and heating from -25 to 30 °C. A winter package with a drain pan heater and a crankcase heater supports operation in frost, and the manufacturer describes the model as a year-round unit. With such figures the air conditioner can be treated as support for heating outside the heating season.
What sets the Teta Mirror apart is its air quality equipment: the iAIR bipolar ioniser, a built-in UV-C lamp, the HD pre-filter and the iClean function. Added to that are Windless technology, a BMS Modbus port and control from an app once a Wi-Fi module is fitted. We quote the installed price after a free assessment, and we discuss the scope of work and any extra charges before installation starts.
Overview and positioning
Teta Mirror is a Rotenso model designed with interiors in mind where black plays the leading role. The manufacturer describes the combination of a matte casing and a glass front panel as a solution that suits arrangements mixing natural materials with glossy accessories. A nominal capacity of 3.5 kW corresponds to a typical room in a Warsaw flat: a bedroom, living room or study, although the final choice depends on sun exposure, ceiling height and the number of people.
Among the features the manufacturer lists as most important are the glass front panel, the iAIR bipolar super ioniser, the UV-C lamp, comfortable Windless airflow, heating at -25 °C and a BMS Modbus port. The numbers confirm solid foundations: SEER 8.5 and class A+++ in cooling, SCOP 4.7 and class A++ in heating, and operation from 18 dB. Such a set positions the model as a proposition for people who care about both looks and air hygiene. It is worth remembering that the claims about ionisation and the UV-C lamp come from the manufacturer, and in everyday use what matters most is clean filters and regular servicing.
The Teta Mirror will do well in a flat where the air conditioner is visible from every spot and is meant to be part of the decor. If you want the unit to work in the cooler part of the year too, the manufacturer declares heating down to -25 °C. We quote the installed price after a free assessment, and we agree the scope of work at the audit, when we can see the wall, the pipe route and the place for the outdoor unit. It is a sensible choice for a flat where the air conditioner is visible and should look good all year.
Cooling and heating technology
The Teta Mirror uses a DC inverter compressor that smoothly matches output to demand. Cooling capacity ranges from 1.0 to 4.6 kW with a nominal value of 3.5 kW, and heating capacity ranges from 1.0 to 4.9 kW with 3.9 kW nominal. The wide range means the unit can run at a small load when it is moderate in the room and raise output when the temperature rises or falls sharply. In practice this limits the number of compressor starts and holds a steadier room temperature, which also helps quieter operation.
The manufacturer also describes densely grooved copper tubes in the heat exchanger, a fan with blades designed on bionic principles and brushless BLDC motors running on many speeds. Turbo mode briefly raises compressor and fan output to reach the set temperature faster. An Eco mode that reduces energy use is available as an option, but the manufacturer describes it as a function available as an option, so we confirm its presence in a particular set when we quote.
Heating is a strong side of this model. The compressor technology, the EXV valve and the year-round operation package are meant to ensure efficient heating, and the range is from -25 to 30 °C. The winter package includes a drain pan heater, which helps remove snow and ice from the outdoor unit, and a compressor crankcase heater that helps starting at low temperature. In cooling the unit works from -15 to 53 °C. The manufacturer notes that the air conditioner can be the only source of heat, but this always depends on insulation and room size.
Comfort and air quality
The indoor unit works in the range of 18 to 44 dB and the outdoor unit is rated at 53 dB. On the lowest speed the unit is therefore very quiet, which matters in a bedroom. Super quiet mode further reduces fan noise, and the sleep function gradually adjusts the temperature during the night to provide good conditions for rest. For the outdoor unit we choose the installation spot so that noise does not reach neighbouring windows.
Windless technology releases air as a gentle, diffused stream through micro-openings in the panel, so you do not feel a direct blast. In heating, the airflow control system first starts the refrigeration circuit and only then the fan, so cold air does not blow at the start. The 4D automatic louvers can be controlled from the remote, and the last position is remembered. A wide airflow angle helps spread the air around the whole room.
In the Teta Mirror air quality is one of the main themes. The iAIR bipolar super ioniser produces negative oxygen ions which, according to the manufacturer, limit the presence of viruses, bacteria, mites and allergens, and also remove odours. The built-in UV-C lamp helps limit bacteria, fungi and other microorganisms in the air. The HD pre-filter catches impurities, and the iClean function dries and cleans the inside of the unit. None of these functions replaces cleaning the filters and an annual service.
Controls and Wi-Fi
A wireless remote is included in the set, as the manufacturer states, and is used to set modes, temperature, fan speed and louver position. It also allows manual addressing of indoor units, which is useful in multi layouts. A timer, sleep function, turbo mode and switching off the display on the unit's panel are available, so that nothing lights up at night. The auto-restart memory restores settings after a power cut. It is also worth knowing that the remote covers all the basic functions, so the app is an extra and not a condition of using the unit.
The manufacturer describes the SMART Wi-Fi function: with a Wi-Fi modem the unit can be controlled with a tablet or smartphone, at home and away. Control through an app is therefore possible. We do not claim, however, that the module is always in the set, because the manufacturer describes it together with the modem, and we confirm its presence when we quote a specific set. The app is useful, for example, for switching the air conditioner on before you come back from work or for checking that it was switched off.
SMART Follow mode uses a temperature sensor in the controller to measure the temperature where you actually are. The SMART 8 °C heating function switches heating on by itself so that an empty flat does not cool below that value. The model has a built-in BMS Modbus port, which allows integration with smart home or building systems, although in an ordinary flat the remote and the app are usually enough.
Design and build
The Teta Mirror has a matte casing in a dark colour and a glass front panel. The manufacturer addresses it to interiors where black plays the main role and stresses its universal, modern look. The combination of matte and glass gives a clear contrast that looks good next to wood, stone or metal accessories. The indoor unit is 820 mm wide, 195 mm deep and 306 mm high, and weighs 9 kg, so it is relatively slim and light. Such a slim body does not dominate a room and suits a place above a bed or a sofa, provided the wall has adequate load capacity.
A glass front is easy to wipe, but a dark surface shows fingerprints and dust, so it is worth wiping it with a soft cloth from time to time. The heat exchanger in the indoor and outdoor units has gold-coated fins with an anti-corrosion coating. This protects the heat exchanger from corrosion and is not a self-cleaning function of the unit, so the filters still have to be cleaned. Condensate can be drained from the left or right side of the indoor unit.
The outdoor unit is rated at 53 dB. In its construction the manufacturer uses an optimised air duct and solutions that limit vibration, but real noise also depends on how the unit is fixed. During installation we pay attention to stable brackets and vibration damping so the unit does not pass sound to the wall. That way the figures on the data sheet have a chance of translating into everyday comfort.
Installation and service
Installation covers the full set of work needed to start the air conditioner: mounting the indoor and outdoor units, up to a few metres of refrigerant, electrical and condensate lines, passing through the wall and neat routing of the installation. Then we evacuate the system and check it for leaks, charge it with refrigerant and start the unit. Finally we check the operating parameters, configure the controls, instruct you on how to use the unit and hand over the warranty documents. Before we begin we agree with you the mounting height of the indoor unit and the place for the outdoor unit, so that the installation is neat and convenient for later servicing.
We agree the scope of work at the free audit and discuss possible extra charges before work: a longer route, drilling through concrete or reinforced concrete, chasing, a condensate pump or work from a lift platform. The maximum installation length for this model according to the manufacturer is 25 m. We quote the installed price after a free assessment, so you know the costs before we start work in your flat.
After start-up the air conditioner needs ordinary upkeep: cleaning the filters every few weeks in the season, checking the condensate drain and a service once a year. During the service we clean the heat exchanger and check the tightness and condition of the outdoor unit. The self-diagnosis function shows an error code on the unit, which makes servicing easier. Keeping things clean is especially important in a model with an ioniser and a UV-C lamp, because dirty filters restrict airflow and worsen the operation of the whole system.
Who this model is for — summary
The Rotenso Teta Mirror 3.5 kW is for people who want to combine a striking dark look with a glass front and extensive air hygiene features. The ioniser, the UV-C lamp and the HD pre-filter may matter to allergy sufferers and families with children, although they do not replace cleaning the filters or airing the room. A SEER of 8.5 in cooling and a SCOP of 4.7 in heating mean sensible energy use, and operation from 18 dB suits a bedroom. It is a sensible choice for a flat where the air conditioner is visible and should look good all year.
Choose this model if the air conditioner is to work in autumn and winter too: the manufacturer declares heating down to -25 °C, and the winter package with two heaters supports operation in frost. If integration with a building system interests you, the BMS Modbus port is built in. Otherwise the remote and the app are enough, and we tell you about the availability of the module in the set when we quote.
It is best to start with a free quote. We check the room, agree the location of the units and the pipe route, and then present the installed price. We quote the installed price after a free assessment, with no obligation. Write or call LeoKlima and we will arrange an audit in Warsaw and the surrounding area and match the capacity to the real conditions in your flat.
