Compatible with a large range of indoor units
and controls
An expansion of Panasonic VRF line up, the Mini ECOi R32 is compatible with a large range
of indoor units and can utilize all Panasonic’s scalable control and monitoring solutions.
Wide range of indoor units, either supporting Panasonic’s
optional R32 refrigerant leak detector alarm or having
built-in detectors provide a great flexibility for all types of
installation.
Scaling your control options from a single zone to
geographically distributed facilities.
LZ2 series are fully compatible with all control and
connectivity solutions from Panasonic. With a wide range
of individual controllers, hotel room controllers, optional
wireless adapters, VRF Smart Connectivity+, easy BMS
connection with S-Link and Panasonic AC Smart Cloud
compatibility. LZ2 series, the most flexible control and
monitoring R32 solution in the market.
Panasonic R32 refrigerant leak detector/alarm (optional)
For compatible indoor unit models, Panasonic offers its
optional external Panasonic R32 refrigerant leak detector
(CZ-CGLSC1). This enables the customer to decide if a
Panasonic R32 refrigerant leak detector is required to
comply with the restrictions, or if the indoor unit may be
safely installed in this room without it. This optional
leakage detection sensor has an integrated alarm buzzer
and can output a signal to a central alarm system in the
building. The device is connected to the remote control
terminals of the indoor unit and can be used in
combination with any of the Panasonic VRF remote
controllers, either wired or wireless.
R32 Pump Down solution
R32 Pump Down solution offers the assurance of
additional safety protection, whilst expanding the potential
installation cases, allowing for installation within smaller
rooms.
Suitable for the Mini ECOi LZ2 range up to 10 HP,
compatible indoor units connected to CZ-CGLSC1 or
integrated Panasonic R32 refrigerant leak detector.

Operation steps: 1 | A leak is detected by the leak detection sensor. 2A | Leak alarm signal is
sent to the outdoor unit. 2B | Indoor unit fan activated and runs at maximum speed. 3 | Pump
Down procedure is activated. 4 | Solenoid valves are closed preventing refrigerant returning
to indoor units. 5 | Outdoor unit is operating in Pump Down mode and check valve only
allows flow to the outdoor unit. 6 | Low pressure switch threshold is reached. Error signal
isolates the outdoor unit, preventing restart.
