(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) A transmission booster is required in a system to which
more than 32 indoor units (26 units if one or more indoor
units of the 200 model or above is connected) are con-
nected.
4) Automatic address setup is not available if start-stop in-
put (CN32, CN51, CN41) is used for a group operation of
indoor units or when multiple indoor units with different
functions are grouped in the same group. Refer to the fol-
lowing page(s). [2-7-2 Single Refrigerant System with
Two or More LOSSNAY Units](page 34)
5) For information about connecting two or more LOSSNAY
units to a system, refer to the following page(s). [2-7-2
