TWIN Daikin Sky Air Alpha R32 System with Outdoor Unit RZAG71NV1 7.1 kW Single-Phase + 2 Indoor Units 3.5 kW

Daikin's multiple systems (Twin, Triple and Double Twin) represent a highly comfortable air conditioning solution suitable for large spaces: it is possible, in fact, to operate up to a maximum of 4 indoor units to air condition multi-storey buildings and large pavilions that require the scattered installation of multiple units.

These systems are composed of:
- 1 outdoor unit in heat pump;
- 2 (twin), 3 (triple) or 4 (double twin) indoor units;
- 1 (twin and triple) or 3 (double twin) distribution joints;
- 1 wired control.

The outdoor units that make up these systems can belong to the Sky Air series:

Alpha Series RZAG-N (7.1 / 10.0 / 12.5 / 14.0 kW with single-phase and three-phase power supply)
The Alpha series is the perfect synthesis in terms of comfort and efficiency thanks to the variable temperature of the refrigerant gas which leads to high seasonal efficiency and excellent reaction speed on the hottest days. Characterized by compact dimensions (a single fan and reduced height), the Alpha range guarantees operation in both heating and cooling mode up to -20°C. Ease of maintenance, thanks to the large accessible surface and the 7-segment display, and maximum efficiency, with energy classes up to A++ in cooling and heating, are the other main features of this series.

Advance Series RZASG-M (7.1 / 10.0 / 12.5 / 14.0 kW with single-phase and three-phase power supply)
The Advance series, characterized by compact dimensions (a single fan), guarantees operation in both heating and cooling modes up to -15°C. Highly efficient operation is demonstrated by energy classes up to A++ in cooling and up to A+ in heating.

Advance Package Series (20.0 / 25.0 kW with three-phase power supply)
The Advance Package series, characterized by small dimensions (only 870 mm high), guarantees ease of maintenance thanks to the large accessible surface and the 7-segment display. Finally, the Advance Package range ensures operation in both heating and cooling modes up to an external temperature of -20°C.

Bearing in mind that mixed configurations are not possible, the following can be connected to the external unit (unless incompatible):

4-way built-in cassette 90x90 Round Flow "SuperCassette" FCAHG-H (7.1 kW)
The Round Flow "Supercassette" FCAHG-H series guarantees high performance and significant energy savings thanks to the high COP values. Its panels guarantee control of the individual deflectors, more uniform air distribution and greater adaptability. Among the main features of this cassette are the presence sensor that directs the air flow away from people and the "Home Leave" mode that manages the internal temperature with energy savings when the rooms are empty.

4-way built-in cassettes 90x90 Round Flow FCAG-B (3.5 / 5.0 / 6.0 / 7.1 / 10.0 / 12.5 kW)
The FCAG-B built-in cassettes with 360-degree air flow are equipped with an enlarged flap for better air distribution so as to reach every point of the room where they are installed despite their very compact dimensions. Their design prevents the accumulation of soot on the ceiling thanks to the Coanda effect. Finally, the Active Circulation AirFlow function guarantees greater comfort and energy savings of up to 10% in heating.

4-way built-in cassettes 60x60 Fully Flat FFA-A (3.5 / 5.0 / 6.0 kW)
The FFA-A built-in cassettes, which integrate perfectly with standard ceiling panels leaving only 8 mm of thickness, allow the control of individual deflectors. Energy consumption, reduced thanks to the small diameter tube exchanger, is also guaranteed by the two optional intelligent sensors that improve both energy efficiency and comfort. Finally, the standard condensate drain pump, with a 630 mm head, increases flexibility and speed of installation.

4-way ceiling-mounted cassettes 90x90 FUA-A (7.1 / 10.0 / 12.5 kW)
The FUA-A ceiling-mounted cassettes, equipped with Inverter, guarantee a more comfortable environment and considerably reduce energy consumption. In addition to the possibility of choosing between 4 air delivery modes, these units can expel air at 5 different angles (from 0° to 60°) and offer the possibility of closing 1 or 2 deflectors to create corner installations or along corridors.

Wall Unit FAA-B (7.1 / 10.0 kW)
The FAA-B wall units, which are the ideal solution for shops, restaurants or offices without false ceilings, are equipped with a flat (removable) front panel in a modern style.

Ceiling suspended units FHA-A(9) (6.0 / 7.1 / 10.0 / 12.5 kW)
The FHA-A(9) series, with an efficiency optimized for all seasons, is the ideal solution for installation in shops, restaurants or offices without false ceilings. These units can cool or heat the rooms very quickly and, once the set temperature is reached, they keep it constant thanks to the energy saving mode that reduces consumption.

Ultra-flat low static pressure duct units FDXM-F(9) (3.5 / 5.0 / 6.0 kW)
The FDXM-F series, which can be easily installed in false ceilings thanks to its compact size, is characterized by an average static pressure of up to 40Pa, which allows the use of the unit with flexible ducts of various lengths, and low energy consumption. These units can be combined with a self-cleaning filter (optional) that guarantees maximum levels of efficiency, comfort and reliability and a Wi-Fi interface (optional) to control the indoor units from anywhere via app.

Medium prevalence ducted units FBA-A(9) (6.0 / 7.1 / 10.0 / 12.5 kW)
The high energy efficiency FBA-A series, which guarantees greater comfort thanks to the stepped air flow control, reduces energy consumption thanks to the inverter-controlled fans. The prevalence of up to 150 Pa allows the use of these units with flexible ducts of various lengths, making them ideal for medium-sized shops and offices. The possibility of changing the prevalence and the extremely quiet operation, with a sound pressure reduced to 29 dBA, make these units extremely high-performance, also thanks to the standard air filter that eliminates dust particles.

High-prevalence ducted units FDA-A (12.5 kW)
The FDA-A series, characterised by seasonal efficiency optimised for all seasons, guarantees a useful prevalence of up to 200 Pa which allows the installation of long ducts with high flexibility of use. These units, whose air flow can be adjusted during installation via the wired control or via regulation on the ducts, are equipped with a standard air filter which retains impurities dispersed in the air. Air-conditioned rooms can be cooled or heated very quickly upon start-up: once the set temperature is reached, the energy saving mode is activated which reduces consumption.
