An Example Of A System To Which Both Ma Remote Controller And M-Net Remote Controller Are Connected - Mitsubishi Electric PUHY-(E)P200 Service Handbook

[ II Restrictions ]

[7] An Example of a System to which both MA Remote Controller and M-NET Remote Controller are connected

(1) Sample control wiring
(2) Cautions
1) Be sure to connect a system controller.
2) M-NET remote controller and MA remote controller can-
not both be connected to the same group of indoor units.
3) Assign to the indoor units connected to the MA remote
controller addresses that are smaller than those of the in-
door units that are connected to the M-NET remote con-
troller.
4) No more than 2 M-NET remote controllers can be con-
nected to a group of indoor units.
5) No more than 2 MA remote controllers can be connected
to a group of indoor units.
6) Do not connect the terminal blocks (TB5) on the indoor
units that are connected to different outdoor units with
each other.
7) Replace the power jumper connector of the control board
from CN41 to CN40 on only one of the outdoor units.
8) Provide an electrical path to ground for the S terminal on
the terminal block for centralized control on only one of
the outdoor units.
9) A transmission booster must be connected to a system
in which the total number of connected indoor units ex-
ceeds 20.
10) A transmission booster is required in a system to which
more than 16 indoor including one or more indoor units
of the 200 model or above are connected.
11) When a power supply unit is connected to the transmis-
sion line for centralized control, leave the power jumper
connector on CN41 as it is (factory setting).
