Does it need a bypass duct?

No. Panasonic states that direct independent fan control eliminates the need for a bypass duct.

Can it be installed horizontally and vertically?

Yes. The official documentation specifies two installation options: horizontal and vertical.

What is the difference between PQ4 and PQ5?

The S-7110PQ41E has four fans, is 1,164 mm wide, weighs 47 kg and reaches 120 Pa. The S-1014PQ51E has five fans, is 1,455 mm wide, weighs 57 kg and reaches 130 Pa. Both are 266 mm high and 701 mm deep.

What capacities does the range cover?

The range includes 7.1, 10.0, 12.5 and 14.0 kW class kits, with single-phase and three-phase combinations depending on the reference.

PACi NX Multi Zone DuctPQ4 / PQ5

One ducted unit. Up to five independent zones.

Q: What control options does it offer?

Panasonic lists two options: individual zone control with the PCZ-EEB749 wall-mounted controller and smart Wi-Fi control via the Aquarea Home app.

The Panasonic PACi NX Multi Zone Duct unit integrates dedicated fans and motors for each outlet, can control up to five independent zones depending on the indoor unit and configuration, allows several fans to be grouped under the same controller, supports horizontal or vertical installation and operates without a bypass duct.

Compare PQ4 and PQ5 View specifications

Up to 5independent zones depending on the indoor unit and the fan and controller configuration.

Zoned airflow

Zoning integrated into the indoor unit itself

Panasonic integrates a dedicated fan and motor for each outlet. Each outlet will typically correspond to one zone, but the PCZ-EEB749 wall-mounted controller can also operate several fans when a single zone needs greater coverage or capacity.

Direct zone control eliminates the need for a bypass duct. The official documentation contrasts this architecture with traditional systems based on a single fan and dampers, where the bypass can dissipate energy.

The range offers single-phase and three-phase kits from 7.1 to 14.0 kW class, with R32 refrigerant, control of up to five zones depending on the indoor unit and configuration, integrated Wi-Fi control and compatibility with the Aquarea Home app.

Independent fans and direct control of each zone

Zoning is built into the indoor unit. Each outlet has a dedicated fan; each outlet will typically correspond to one zone, but several fans can also be grouped under the same controller to serve a single zone. The range can manage up to five independent zones.

Multi-zone control

Airflow is generated where there is demand

Panasonic describes four differences compared with a traditional system using a single fan and dampers.

Dedicated fansEach outlet integrates its own fan and motor.

Flexible zone configurationEach outlet can serve an independent zone or be grouped with other fans under the same controller.

No bypass ductDirect control avoids having to discharge excess air through a bypass.

Operation on demandThe documentation states that the fans only operate when required.

GroupingSeveral fans can serve the same zone.

PQ4 and PQ5: two indoor units in a range of up to five zones

Both versions are 266 mm high and 701 mm deep. They differ in the number of fans, width, weight and maximum static pressure. The actual number of zones can be lower than the number of fans when several outlets are grouped under the same controller.

Two control options

The official page summarises two options: individual control with the PCZ-EEB749 wall-mounted controller and smart Wi-Fi control via Aquarea Home.

Control options

Local zone control or smart remote management

The wall-mounted controller sets the zone setpoint and can operate one or more fans. The shared Wi-Fi connection allows the complete system to be managed through Aquarea Home.

Option A

PCZ-EEB749

Individual zone control via a wall-mounted controller. A single controller can also operate several fans to increase the coverage or capacity of one zone.

LocationZone wall

FunctionControl of one zone with one or more fans

Option B

Wi-Fi + Aquarea Home

Smart Wi-Fi control via Aquarea Home, with centralised remote control, a weekly timer and a shared connection for all zones. The module includes an Ethernet port and can be positioned outside the unit to improve router coverage.

ConnectionIntegrated Wi-Fi module with Ethernet port

ManagementSmartphone or tablet

Panasonic condition for Modbus

The Wi-Fi module must be disconnected when the unit is connected to Modbus.

Frequently asked questions

How many zones can the unit control?

The Panasonic PACi NX multi-zone range can control up to five independent zones depending on the indoor unit, the number of available outlets and how the fans are grouped. Each outlet has a dedicated fan and motor, and several fans can be grouped under the same controller to serve a single zone.

Can one controller operate several fans?

Yes. Panasonic states that the PCZ-EEB749 can operate several fans when a zone needs greater coverage or capacity. As a result, the actual number of zones can be lower than the number of available fans.

Does it need a bypass?

No. Direct independent fan control eliminates the need for a bypass duct.

What control options are available?

Individual zone control with the PCZ-EEB749 or smart Wi-Fi control through the Aquarea Home app.

Are Wi-Fi and Aquarea Home two different options?

Not in the official classification. Panasonic presents Wi-Fi as the connectivity that enables smart control through Aquarea Home. For this reason, the article shows two overall options: wall-mounted controller and Wi-Fi with Aquarea Home.

Can it be installed vertically?

Yes. The official documentation specifies horizontal or vertical installation. The drawing on this page is for guidance only; the installation must be defined using the official drawings.

What static pressure does it offer?

PQ4 offers 10 to 120 Pa and PQ5 10 to 130 Pa, with 30 Pa as the nominal factory setting.

What capacities are available?

7.1, 10.0, 12.5 and 14.0 kW class kits, in single-phase or three-phase combinations depending on the reference.
