[1] Functions and Specifications of MA and ME Remote Controllers

There are two types of remote controllers: M-NET (ME) remote controller, which is connected
on the indoor/outdoor transmission line, and MA remote controller, which is connected to
each indoor unit.

Making group changes
(Note 1) MA remote controller includes MA remote controllers, MA compact remote controllers, and wireless remote controllers.
(Note 2) M-NET remote controller includes ME remote controllers and compact remote controllers.
(Note 3) Depending on the system configuration, even a single refrigerant system may require an address setting.
(Note 4) Either an MA remote controller or an M-NET remote controller can be connected to a group of multiple-refrigerant systems
or when a system controller is connected.
2. Selecting the Best Type of Remote Controller
Select either the MA remote controller or the M-NET remote controller to take full advantage of a given system.
The following information is provided as a reference for selection.
MA remote controller (Notes 1, 2)
• Low chances of system expansion and grouping
changes are expected.
• Grouping (floor plan) has been decided at the
time of installation.
(Note 1) M-NET remote controllers and MA remote controllers cannot both be connected to the same group of indoor units.
(Note 2) A system controller must be connected to a system that has both MA remote controllers and M-NET remote controllers.

Non-polar 2 wires
✻
Daisy-chain the indoor units with non-polar
2 wires when running a group operation.
Connectable to any indoor unit in the
group
Each indoor unit can individually be
interlocked with a ventilation unit.
(Registered on the remote controller in
the same group)
MA remote controller wires between
indoor units require rewiring.

indoor/outdoor transmission line
Each indoor unit can individually be
interlocked with a ventilation unit.
(Registered on the remote controller)
Indoor unit and remote controller
addresses must be changed, or the
registration information must be changed
using MELANS.
M-NET (ME) remote controller (Notes 1, 2)
• High chances of centralized installation of remote
controllers, system expansion, and grouping changes.
• Grouping (floor plan) has not been decided at the
time of installation.
• Direct connection of the remote controller to the
Lossnay inside the heater-humidifier.
