*1. MA remote controller refers to MA remote controller (PAR-20MAU, PAR-21MAAU, PAR-30MAAU), Simple MA Remote
Controller (PAC-YT53CRAU), and wireless remote controller.
*2. Either the MA remote controller or the ME remote controller can be connected when a group operation of units in a sys-
tem with multiple outdoor units is conducted or when a system controller is connected.

Local Remote Controller Selection Tips

MA remote controller and ME remote controller have different functions and characteristics. Choose the one that better suits
the requirements of a given system. Use the following criteria as a reference.
MA remote controller
There is little likelihood of system expansion and
grouping changes.
Grouping (floor plan) has been set at the time of in-
stallation.
*1. ME remote controller and MA remote controller cannot both be connected to the same group of indoor units.
*2. A system controller must be connected to a system to which both MA remote controller and ME remote controller are con-
nected.

Non-polarized 2-core cable
To perform a group operation, daisy-
chain the indoor units using non-polar-
ized 2-core cables.
Connectable to any indoor unit in the
group
Each indoor unit can individually be in-
terlocked with a ventilation unit. (Set up
via remote controller in the group.)
MA remote controller wiring between in-
door units requires rewiring.

Each indoor unit can individually be inter-
locked with a ventilation unit. (Set up via
remote controller.)
Either the indoor unit address and remote
controller address must both be changed,
or the registration information must be
changed via MELANS.
ME remote controller
There is a likelihood of centralized installation of remote control-
lers, system expansion, and grouping changes.
Grouping (floor plan) has not been set at the time of installation.
To connect the remote controller directly to the OA processing
unit.
