The Ariston Prios Net 35 MUA1 is a wall-mounted monoblock split air conditioning system with a nominal cooling capacity of 3.4 kW and a nominal heating capacity of 3.7 kW, is the most commonly specified capacity in the Prios Net range, suited to living rooms and larger bedrooms. The unit features factory-integrated Wi-Fi (supplied with a Wi-Fi key) for control via the Ariston Clima app, together with ECO Mode for reduced energy consumption, Turbo Mode for rapid temperature pull-down, Advanced Air Purification to remove harmful gases and fine particles, a Silence Function for ultra-quiet operation, Self-Cleaning on both indoor and outdoor units, and Follow Me temperature sensing via the remote control. Charged with low-GWP R32 refrigerant, it achieves Class A++ cooling efficiency (SEER 6.1) and up to Class A+++ heating efficiency in the warmer season (SCOP 5.1). Product code: 4213071.

🔴 Installer Notice — F-Gas Regulations
R32 refrigerant is mildly flammable (A2L classification). Installation, commissioning, and servicing must be carried out by a qualified F-Gas certified engineer in accordance with UK F-Gas Regulations. See the certification requirement above.
🟠 Matched System — Indoor & Outdoor Units
The Prios Net 35 MUA1 complete set pairs the 35 UA1-I indoor unit (code 4213041) with the 35 MA1-O outdoor unit (code 4213047). Standard refrigerant charge covers pipe runs up to 5 m; additional R32 charge at 12 g/m is required beyond this, up to the 25 m maximum.
🟢 Manufacturer-Verified Performance Data
All performance figures on this page — cooling and heating capacities, EER, COP, SEER, SCOP, sound levels, and dimensions — are sourced directly from Ariston UK's official Prios Net datasheet (library.ariston.co.uk), not estimated or interpolated from adjacent models.
Factory-Integrated Wi-Fi & Ariston Clima App

The Prios Net range is supplied with a built-in Wi-Fi key, allowing full smartphone control through the Ariston Clima app without needing to purchase separate connectivity hardware. Schedule, monitor, and adjust the system remotely — useful for pre-conditioning a room before arrival or checking on a property while away.

ECO Mode

ECO Mode optimises system performance specifically to reduce energy consumption, capping output to favour economy during continuous background operation. This is particularly effective for maintaining a comfortable temperature in occupied rooms over extended periods without drawing peak power.

Turbo Mode

Turbo Mode drives the compressor and fan to maximum output so the room reaches the desired temperature as quickly as possible. Once the setpoint is achieved, the system automatically steps back to standard operation — useful for returning to a hot or cold room and wanting fast relief.

Advanced Air Purification

The unit's Advanced Air Purification function actively removes harmful gases and fine particles from the conditioned air, delivering cleaner air quality alongside temperature control. This is a genuine manufacturer-specified feature of the Prios Net range, not a generic filter claim.

Silence Function & 12-Speed Fan

The indoor fan operates across 12 speed levels, including a dedicated Silence Function for ultra-quiet night-time or study operation. At its lowest setting the indoor unit reaches sound pressure levels as low as 21 dB(A) — well below typical background noise in most rooms.

Self-Cleaning — Indoor & Outdoor

Both the indoor and outdoor units feature Self-Cleaning Functions that keep the system clean for better performance and durability, reducing the build-up of dust and debris on the heat exchangers between engineer service visits.

Follow Me Temperature Control

The Follow Me Function delivers precise temperature control by using the remote control's own sensor as the reference point, rather than the wall-mounted indoor unit — ensuring the system targets the temperature exactly where the occupant is located.

Vertical Swing & Even Distribution

Automated vertical swing louvre control distributes airflow evenly across the room rather than concentrating it in one direction, improving comfort consistency — particularly valuable at this unit's rated airflow of up to 540 m³/h on high speed.

Why is the 35 MUA1 a popular mid-range choice?
At 12 kBTU (3.5 kW nominal cooling, 3.7 kW nominal heating), the 35 MUA1 covers a broad range of typical room sizes while achieving a strong SEER of 6.1 and SCOP of 5.1 in the warmer heating season (Class A+++).
What does the EER and COP tell me?
EER (Energy Efficiency Ratio) and COP (Coefficient of Performance) describe efficiency at a single, standard test condition — EER 3.28 for cooling and COP 3.72 for heating on this model. The SEER and SCOP figures in the seasonal efficiency section better reflect real-world annual performance across varying conditions.
What is the maximum pipe run for this model?
The outdoor unit for the 35 MUA1 supports an ODU–IDU maximum length of 25 m and a vertical maximum distance of 10 m. The factory refrigerant charge covers the first 5 m; beyond that, an additional 12 g/m of R32 is required, to be added by a qualified F-Gas engineer.
How much heating running cost should I expect?
Ariston's datasheet lists an annual electricity consumption of 706 kWh for heating in the warmer season assessment (Class A+++), or 945 kWh under the average season assessment (Class A+). Actual running costs depend on your electricity tariff and usage pattern.
Is the outdoor unit noise level suitable for a typical UK garden or side return?
The outdoor unit's sound power is 63.0 dB(A) with a nominal sound pressure of 56.0 dB(A). As with any outdoor condensing unit, positioning away from neighbouring windows and boundaries is recommended good practice.
