<Initial settings>
Turn ON when the centralized controller is connected to the outdoor unit.
• SW2-1 must be turned ON if a central controller is connected to the system.
An
example of this would be a
TC-24, EB50A,
AG150,
AE50 or
AE200. If SW2-1 is not turned
on, while using a central controller
, in rare
circumstances problems may be encountered such as indoor units not responding to group commands.
Therefore, turning SW2-1 ON is
recommended if a central controller is used. • Group setting of 2 or more
A-IC units
which is connected to branch box via centralized controller is not allowed.
