The Panasonic CU-4Z80CBE is a 4-connection Free Multi Z outdoor condensing unit, built to run up to four independently controlled indoor units from a single external condenser. It uses the R32 refrigerant and an inverter-driven rotary compressor to deliver flexible, room-by-room heating and cooling across mid-sized homes without needing four separate outdoor units.
Rated at 8.0kW nominal cooling and 9.4kW nominal heating, the CU-4Z80CBE supports a combined indoor capacity range of 4.5kW to 14.7kW, and reaches A+++ SEER efficiency, making it a strong fit for larger family homes needing four separately controlled zones.
Important: F-Gas Qualified Installation Required
This unit is charged with R32, a fluorinated greenhouse gas covered by F-Gas Regulations. Installation, commissioning, and any refrigerant handling must be carried out by an F-Gas certified engineer. See the certification form above before ordering.
Please Note: Minimum Two Indoor Units Must Be Connected
The CU-4Z80CBE is designed to run 2 to 4 indoor units — at least two must be connected for the system to operate correctly. The combined nominal cooling capacity of all connected indoor units must fall within the 4.5kW–14.7kW connectable range, so check the total against the specific indoor unit combination before ordering, particularly on four-zone layouts.
Good to Know: A+++ SEER Efficiency
Achieves an SEER rating of 8.50 (A+++) and an SCOP of 4.70 (A++), placing it among the more efficient units in Panasonic's domestic Free Multi Z range.
Four Independent Zones From One Outdoor Unit
A single outdoor unit drives up to four rooms with individual temperature control on each, reducing outdoor footprint compared to installing separate condensers for a multi-room project.
Inverter-Driven Rotary Compressor
The inverter compressor modulates output to match real-time demand across all connected rooms rather than cycling on and off, which improves comfort, reduces electricity use, and lowers operating noise.
A+++ SEER Efficiency
Achieves an SEER rating of 8.50 (A+++), placing it at the top of the current European energy label scale for cooling efficiency.
Wide Indoor Unit Compatibility
Compatible with Panasonic's Etherea wall-mounted, TZ super-compact wall-mounted, 60x60 cassette, and low static pressure hideaway duct indoor units, so each connected room can use the indoor style that best suits the space.
R32 Refrigerant for Lower Environmental Impact
R32 has a lower global warming potential than the R410A refrigerant it replaces, while also improving system efficiency — helping the unit meet current and future F-Gas phase-down requirements.
Wide Heating Operating Range
Rated to operate in heating mode down to -15°C outdoor ambient, making it a genuine year-round heat pump solution for UK winters, not just a summer air conditioning unit.

How many indoor units can I connect to the CU-4Z80CBE?
Between 2 and 4 indoor units can be connected. At least two must be connected for the system to run — it cannot be operated with only one indoor unit fitted.
What indoor unit types are compatible with this outdoor unit?
The CU-4Z80CBE supports Panasonic's Etherea wall-mounted, TZ super-compact wall-mounted, 60x60 grid cassette, and low static pressure hideaway duct indoor units, allowing different room types to use different indoor styles on the same outdoor unit.
Does this outdoor unit need an F-Gas certified installer?
Yes. The unit is charged with R32 refrigerant, which falls under F-Gas Regulations. Installation and any refrigerant work must be carried out by an installer holding valid F-Gas certification, which we verify before shipment.
What is the maximum total indoor capacity I can connect?
The combined nominal cooling capacity of all connected indoor units must fall between 4.5kW and 14.7kW. Exceeding this range is not supported by the manufacturer.
How efficient is the CU-4Z80CBE?
It achieves an SEER of 8.50 (A+++) and an SCOP of 4.70 (A++), among the more efficient units in Panasonic's current domestic Free Multi Z range.
Can this unit provide heating in cold UK winters?
Yes. The CU-4Z80CBE is rated to operate in heating mode down to -15°C outdoor ambient temperature, making it suitable as a genuine year-round heat pump rather than a cooling-only summer unit.
