(2) Cautions
1) ME remote controller and MA remote controller cannot both be
connected to the same group of indoor units.
2) No more than 2 ME remote controllers can be connected to a
group of indoor units.
3) Do not connect the terminal blocks (TB5) on the indoor units that
are connected to different outdoor units with each other.
4) Replace the power jumper connector of the control board from
CN41 to CN40 on only one of the outdoor units.
(not required if power to the transmission line for centralized
control is supplied from a controller with a power-supply func-
tion, such as GB-50ADA)
5) Provide an electrical path to ground for the S terminal on the ter-
minal block for centralized control on only one of the outdoor
units.
6) When the number of the connected indoor units is as shown in
the table below, one or more transmission boosters (sold sepa-
rately) are required.
To connect two transmission boosters, connect them in parallel.
(Observe the maximum number of connectable indoor units that
are listed in the specifications for each outdoor unit.)

included in the connected indoor units

but only a single outdoor unit can be connected in an HVRF system.
7) When a power supply unit is connected to the transmission
line for centralized control, leave the power jumper connec-
tor on CN41 as it is (factory setting).
(3) Maximum allowable length
1) Indoor/outdoor transmission line
Same as [5] 3.
2) Transmission line for centralized control
Same as [5] 4.
3) ME remote controller wiring
Maximum overall line length
(0.3 to 1.25mm
m1 10m [32ft]
m2+m3 10m [32ft]
If the standard-supplied cable must be extended, use a
cable with a diameter of 1.25mm
of the cable that exceeds 10m [32ft] must be included in
the maximum indoor-outdoor transmission line distance
described in (1).
When connected to the terminal block on the Simple re-
mote controller, use cables that meet the following cable
size specifications: 0.75 - 1.25 mm
4) Maximum line distance via outdoor unit
