*1. The automatic indoor/outdoor address
setup function is not available when any
HS is connected to a given system.
(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 MA remote controllers can be connected to
a group of indoor units.
3) When the number of the connected indoor units is as shown
in the table below, one or more transmission boosters (sold
separately) are required.
To connect two transmission boosters, connect them in par-
allel. (Observe the maximum number of connectable indoor
units that are listed in the specifications for each outdoor
unit.)
When the W/WP/WL200 and
W/WP/WL250 models are not in-
cluded in the connected indoor units
When the W/WP/WL200 and
W/WP/WL250 models are included
in the connected indoor units
The table above shows the number of transmission boost-
ers that is required by the system with four HBCs. For each
HBC added or subtracted, subtract or add two indoor units.
4) Automatic address setup is not available if start-stop input
(CN32, CN51, CN41) is used for a group operation of indoor
units or when multiple indoor units with different functions
