Complete F-Gas Certification Form →The Ariston Prios Net 25 MUA1 is a wall-mounted monoblock split air conditioning system with a nominal cooling capacity of 2.9 kW and a nominal heating capacity of 2.9 kW, is the entry-level model in the range, suited to smaller rooms and 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 6.3) and up to Class A+++ heating efficiency in the warmer season (SCOP 5.1). Product code: 4213070.
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.
The Prios Net 25 MUA1 complete set pairs the 25 UA1-I indoor unit (code 4213040) with the 25 MA1-O outdoor unit (code 4213046). 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.
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.
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 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 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.
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.
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.
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.
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.
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 466 m³/h on high speed.
